What Does 10 4 Mean
In popular culture – Ten-codes, especially “10-4” (meaning “understood”) first reached public recognition in the mid- to late-1950s through the popular television series Highway Patrol, with Broderick Crawford, Crawford would reach into his patrol car to use the microphone to answer a call and precede his response with “10-4”.

Ten-codes were adapted for use by CB radio enthusiasts.C.W. McCall ‘s hit song ” Convoy ” (1975), depicting conversation among CB-communicating truckers, put phrases like “10-4” and “what’s your twenty?” (10-20 for “where are you?”) into common use in American English. The movie Convoy (1978), loosely based on McCall’s song, further entrenched ten-codes in casual conversation.

The ten-codes used by the New York Police Department have returned to public attention thanks to the popularity of the television series Blue Bloods, However, the ten-codes used by the NYPD are not the same as those used in the APCO system. For example, in the NYPD system, Code 10-13 means “Officer needs help,” whereas in the APCO system “Officer needs help” is Code 10-33.

What does 10-4 actually mean?

10-4 is one of the so-called ten-codes, or radio signals, invented by the Association of Public-Safety Communications Officials-International (APCO).10-4 is an affirmative signal: it means “OK.” The ten-codes are credited to Illinois State Police Communications Director Charles Hopper who created them between 1937–40 for use in radio communications among cops.

Ten-Four Day ~ for decades, Oct 4 has been a day to salute radio operators. pic.twitter.com/zpsDNPtorQ — Chase’s Calendar (@ChasesCalendar) October 4, 2017 In the 1930s, radio technology was still relatively new and limited. For starters, there were limited police radio channels, so officers couldn’t stay on the line too long or else others wouldn’t be able to get through.

The ten-codes were invented to communicate information quickly and clearly. The use of the number 10 before all of the codes was another workaround. It took a split second for the motor-generator in the radios to warm up, and so the first syllables of a radio transmission were often lost. The 10 was used as a placeholder to give the motor-generator time to speed up enough to hear the second part of the code.4 was simply chosen to mean “acknowledgement” of a message ( 10-3 meant “stop transmitting” in case you wanted to know).

These handy codes were quickly adopted by others communicating via radio, such as CB (Citizen Band) radio enthusiasts and truckers. Helping to popularize 10-4 in the mainstream was the 1950s TV crime drama Highway Patrol, starring Broderick Crawford, known for starting his conversations on his radio with 10-4.

Why You Can Only Have 150 Friends (According to Science)

Oh, the ’50s. The expression 10-4 further spread into popular culture when it was featured in C.W. McCall’s 1975 song “Convoy,” where he uses trucker CB radio slang like breaker one-nine (a radio channel used by truckers) and 10-4, The song went number one on the charts in the US and abroad and was even made into a movie in 1978.10-4 has shown up in hip-hop lyrics, too, like Ghostface Killah’s 2004 “Beat the Clock,” where he raps: “ten four, may day-may day / Callin’ all cars, callin’ all cars.” This use is inspired by 10-4 in cop-speak.

Why does 10-4 mean okay?

Some truck driver slang makes sense with little to no explanation. Bambi, for example, signals that there’s a deer nearby; and diesel fuel is sometimes called go-go juice, But unless you’re familiar with the history of radio, the origins of 10-4 —meaning “Message received” or “OK”—may not seem so obvious.

  • As Dictionary.com reports, 10-4 is part of a collection of “ten-codes” developed by Illinois State Police communications director Charles Hopper in the late 1930s.
  • Two-way car radios had just been invented, and the codes were an especially efficient way for police officers to transmit messages to each other and back to headquarters.

In 1940, the Associated Police Communications Officers, or APCO (now the Association of Public-Safety Communications Officials International), published a list of nearly 100 ten-codes to help standardize usage across state lines.10-1 meant “Receiving poorly,” 10-2 meant “Receiving well,” 10-3 was for “Stop transmitting,” 10-4 signaled “Acknowledgement,” and so on.

  • Tacking a 10 before each number was a troubleshooting tactic.
  • Since radio motor-generators weren’t yet high-tech enough to jump into action as soon as someone started transmitting, the person on the receiving end frequently didn’t hear the beginning of the message.
  • But if the beginning of every message was the same meaningless 10, it didn’t matter.

Thanks in part to how often Broderick Crawford uttered “10-4” on the 1950s police drama Highway Patrol, the phrase gained a broader audience. And when truck drivers started communicating via two-way radios, they co-opted that and other ten-codes, too.

  • More Articles About Truck Driving: Their radios were typically citizens band radios, or CB radios, a type of short-distance device that the Federal Communications Commission started regulating in the 1940s.
  • CB radio usage boomed in the wake of the 1973 oil crisis, when 55-mph speed limits were instituted across the nation and truckers needed a way to warn each other about speed traps,

But the technology wasn’t just used for one purpose or by one demographic. As The New York Times put it in 1983, CB radios were “a sociological phenomenon that turned the highways of the 1970s into a giant chattering social circle.” Truck drivers’ CB radio shorthand took on a life of its own during the era, bolstered by the popularity of C.W.

What does 10 2 and 10-4 mean?

10-2: Receiving well.10-3: Stop transmitting.10-4: Ok, message received.10-5: Relay message.10-6: Busy, stand by.

What is a response to 10-4?

5 Easy Ways to Respond to 10 4

10-4 literally means “OK” and it’s used as an acknowledgement. If you’re talking to someone over a citizens band radio, known commonly as a CB radio, you’ll hear “10-4” all the time. It means “OK,” or, “Acknowledged.” You would say 10-4 whenever someone says something to you specifically. Advertisement

  1. If you respond at all, respond to their other comments.10-4 is just a signal to indicate that someone understands you. You don’t need to respond to the 10-4, but if there’s anything else accompanying the message, you can 100% respond to that.
    • For example, if you ask someone, “, can you keep an eye out for dangers on the road ahead?” and someone replies, “10-4, anything in particular you’re worried about?” you might say, “Thanks. I’ve got a tire with low pressure, so anything that might pop a tire, over.”
    • If all the other person says is, “10-4,” you don’t need to say anything. You can say, “10-4, over” if you’d like to let them know you’re done speaking if you’d like.
  1. 1 Reply with “10-4” when someone messages you directly. Citizens band frequencies are open to the public, which means that anyone with a CB radio who happens to be in range can communicate with you. If anyone calls you for any reason, you would say “10-4” just to acknowledge that you hear them.
    • In a professional setting (i.e. you work as a truck driver), you’d know if someone is messaging you when they reference your callsign.
    • You do not need to reply to general messages that don’t concern you or aren’t addressed to you specifically.
  2. 2 Use “10-4” to acknowledge and confirm a request. If someone asks you to do something, like look out on the road ahead for stopped vehicles, or give you the coordinates of a location, you can say “10-4” as a way of saying “I hear you, and I will do that.”
    • A 10-4 on its own would signal that you’re accepting the request, just to be totally clear.
  3. 3 Say “10-4, over” to let people know when you’re done talking. If you were in the middle of a back-and-forth conversation, you use the word “over” to signal that you’re done speaking. It doesn’t necessarily mean that the conversation is over, just that you don’t have anything else to say and you’re awaiting a response.
    • If you did want to end the conversation, you would say, “10-4, out.” This means you understand what they said and you’re getting off of the radio or leaving.
    • You never actually say “over and out” if you’re using a proper CB channel. You can totally use it casually, though!
    • In more laid back environments, “10-4, Rodger” can be used in place of “10-4, over.”

  1. You only need to use 10-4 if your job/hobby uses ten codes. The ten codes are a set of 200 formal codes (all of which start with 10 followed by another number). The ten codes were invented in the 1930s to make it easier for people using CB radios to communicate with one another. If your job or hobby club uses the ten codes, use 10-4 instead of “affirmative” or “okay.”
    • “Plain English” is the alternative to ten codes. If people are using regular conversational English over the radio, they’re using plain English. You don’t need to use “10-4” if people are using plain English.
  1. Truckers, ambulance drivers, and police officers. Ten cods are common in these professions where you need to communicate quickly in a potential emergency situation. If a trucker has mere seconds before running into an obstacle, or a police officer needs help as quickly as possible, the ten codes make it easy to communicate complex information quickly and efficiently. Other commonly used ten codes include:
    • 10-1, which means “I’m having trouble hearing you,” and 10-2, which means, “you’re loud and clear.”
    • 10-6, which is a kind way of saying, “I’m busy, please leave me alone.”
    • 10-13, which is used to signify a weather report or road conditions update is coming up.
    • 10-20, which is means, “My location is currently”

Do people still say 10-4?

Agencies have recognized that some codes will still be used during normal radio trans- missions, such as 10-4, which is recognized as ‘okay,’ ‘copy’ or ‘acknowledged.’ Those agencies that have adopted plain language have not reprimanded officers who slip and occa- sionally use codes during this transition.

What does 10 20 mean?

What’s Your 10-20? One of the questions we’ve been asked most often over the past month is “what does 10-20 mean”? It’s a question that can be answered easily, actually. We took inspiration from CB Radio slang. In fact, the following is from If you hear a truck driver say “10-20” on their CB radio, it’s just another way to say “Your current location.” And offers a little more history: The phrase essentially means, “What is your location?” or “Identify your position,” but is a corrupted phrase from the original “10-20” used by law enforcement to verbally encode their radio transmissions so that non-police listeners would not easily discover police operations, as well as to communicate quicker and more efficiently by standardizing frequently used phrases.

These verbally-coded messages were called “10 codes”, of which “10-20” stood for “Identify your position,” or “Where are you?” originally. Other such codes include “10-7” meaning the officer was busy such as with a traffic pull-over, “10-8” meaning that the officer was back on patrol such as from having just written a citation, the popular “10-4” as an affirmative, “10-10” as a negative and “10-22” to disregard a previous transmission have only seen light integration into common use.

It was not uncommon for a city to have its own set of particular 10-codes for other phrases frequently used particular to that locale. So that’s where we took our inspiration from. More importantly, though, is ensuring that your 10-20 is protected online.

And by that we mean that your location, your brick and mortar address, should be claimed and consistently presented across a number of search engines, review sites and mapping technologies. Why? Because when someone searches for your business or keywords associated to it, you’ll have a greater chance of turning up on Google, Bing, Yahoo, Yelp, Facebook or Tom Tom, to name a few online listing technologies.

And in today’s local search-driven economy, being able to pinpoint your location on the maps and search engines that drive the small business economy is not just good practice, it is critical to the survival of your livelihood. Because if your small business doesn’t show up as a search engine result, your competitor’s will.

Why do truckers say breaker breaker?

What are some of the Trucker Sayings? – ” Breaker breaker 1-9, anyone got a copy?” This is a trucker saying that is widely used commonly as a courtesy call for the truckers to get access to the CB radio Channel. The “1-9” refers to channel 19 on the CB radio, which is the most popular channel.

This phrase of the trucker lingo is something truckers will say before they can address something on the channel 19 radio without interrupting other drivers that are talking. It is important to note that some of the trucker sayings are also used by law enforcement agencies, military, hammer operators, and other occupations.

Most of the sayings are however unique to the CB radio.

Why do soldiers say Roger?

Where does the expression “Roger that” come from ? It is also used in maritime communications to acknowledge communications. | Notes and Queries | guardian.co.uk Where does the expression “Roger that” come from ? It is also used in maritime communications to acknowledge communications. Alan Doory, Rio de Janeiro, Brazil

  • “Roger” was “phonetic” for “R” (received and understood”. In radio communication, a “spelling alphabet” (often mistakenly called a “phonetic alphabet) is used to avoid confusion between similarly sounding letters. In the previously used US spelling alphabet, R was Roger, which in radio voice procedure means “Received”. While in the current spelling alphabet (NATO), R is now Romeo, Roger has remained the response meaning “received” in radio voice procedure. In the US military, it is common to reply to another’s assertion with “Roger that”, meaning: “I agree”.
    • Major David Null, Auxiliary USAF, Claremont, CA USA
  • In the RAF, the expression “Roger Willco” (“received, will cooperate”) was used to acknowledge a request or order; It might still be, for all I know. I once had an idea for a television comedy series that followed the exploits of a roguish NCO called Sergeant Willco but was upstaged by Phil Silvers.

  • I was told during my Navy training that ROGER stands for Received Order Given, Expect Results.

My name Rafael Gonzales.I sevred in Vietnam January 1970 to January 1971.I became a radioman on are about March of 1970. Being hispanic my vocabulary was very limited.I had trouble pronouncing many words. One day while on an operation, we were crossing a booby trap infested area.each taking their turn to cross an open area., I was with Alpha Company 1st platooon (don’t quite remember).as I was making my crossing.a previous call came in.asking me if I receive the last message. I stead of saying “Affirmative” meaning “Yes”.to save my life I could not pronounce “Affirmative”.and so I came up with “Roger That”.like I said I could not pronounce the affirmative. There is more to this.if interested in more details.please feel free to contact me.this happen on or about April 1970.thank you. Sincerely, Rafael Gonzales Charlie Two Charlie Squad Leader.Nam 70-71 Rafael Gonzales, Houston, Texas U.S.A.

  • Roger or Roger That does NOT mean “agreement”. It just means the entire message was received. Wilco, as in WILL COMPLY was the old term for will comply. Wikipedia “roger that” or try websites that deals with radio or military terminology.

  • My name is Roger Thatney and I am 91 years old. I was serving as a testing pilot at the beginning of WW2 for the US Navy and since our plane equipped radio systems were not very advanced the signal was often getting lost and only parts of the conversations were heard, so whenever my name was called other pilots only heard “Roger.”, or “.That.”, so we were often joking about the signal quality and eventually instead of saying “I understand” they started jokingly saying “Roger That” and everyone knew exactly what they meant. Later the phrase caught up with the radio signal engineers who were working at making our planes getting better reception as well as creating plane radar systems and the phrase was later used to name aircraft radio equipment developing projects – on May 3rd, 1941 project “Roger” was created at the Naval Aircraft Factory to install and test their, then “new”, “airborne radar equipment”. The equipment proved to be very useful in the next few months so the phrase “Roger That” spread across all of the Navy and later other US Army units. The rest was history.

  • Hmmm, very interesting stories here. Now I understand why all pilot and captain names were “ROGER” in old USA movies in the Turkish translation. I think many years ago interpretation was not successful in Turkey.
    • Umit Golgeci, Finike, Antalya, Turkey
  • All the stories are very interesting. We use “Roger That” when corresponding on our business radios. All of them apply to us. The response from Roger surely has a lot more credibility. Also, Thank You Roger and all you veterans for making it possible for me to live a cherished life in the USA.

Well fellow Vets.I am sorry to know that you find me to be a fake.and I can understand as to why.but all I wanted to do was to let someone know how this Roger That expression got started.and for not knowing what unit I was in, I was in Country for a very short time when I became a Radioman and I really do not remember if it was the First Platoon or the Second Platoon for Alpha Company.and you Sir(s), would have been very proud of the many things I did for my Country.around May of 1970 or there a-bouts I was transferred to Charlie Company Second Platoon.days later I became a Squad Leader (Third Squad).I was wounded twice and among other things that I do not feel comfortable to write about. I hope and wish you Men the best.I do not want to cause you to anger.if you do not believe me, then let’s wait for the moment when we stand before our Maker and have him reveal the truth to all things.May God Speed. Sincerely, Rafael Gonzales Rafael Gonzales, Houston U.S.A.

  • Don’t mind them, they apparently still have a lot to prove. I have been with over a dozen units detached and deployed all over, and just had to pull up records to fill out my last clearance investigation.

  • Back in the day, “Roger That” either meant “Yep”,. or more typically “Hell Yeah”!

  • BAHAHAH I find it hilarious that there are two different stories of people claiming to have been a part of the origin of the phrase JUST on this blog. That’s cute.

What does 10-4 Roger mean?

Roger Roger, 10-4, Over & Out We all know CBs are an invaluable form of communication in the bush. But do we know how to use them correctly? CB radios are a trusty companion when we head bush. Whether we’re going remote or just taking off for a weekend, their utility is hard to fault.

For vehicle convoys, they’re a great way to keep in touch with fellow travellers while on the road. If one of your companions leaves for a spot of bushwalking, the CB in their pocket and the CB in your rig create insurance against becoming lost or snake bite. And a polite discussion over a short-wave radio sure beats volleys of barked directions between driver and travel partner when it comes time to reverse a rig into a tight space — it’s no wonder CBs are sometimes called marriage savers.

More broadly, CB radios help you keep in touch with the world around you. Listen to Channel 40 and you can find out about road conditions from truckies using the same roads as you. On remote tracks, you’ll find roadside signs with recommended channels to monitor in the event someone’s bogged or in some other difficulty. The distance our CB conversations can travel is dependent on a many variables. These include the quality of the product, quality of installation, antenna choice, mount location, power output, terrain and even atmospheric conditions. But you should expect around 5–25km range.

  1. As radio waves work on a line of sight, you’ll generally get as much range as you can actually see.
  2. And if you’re struggling to get the distance you need, head for higher elevation.
  3. CHANNEL SELECTION Under Commonwealth radiocommunications legislation, we’re generally not authorised to use certain channels.

These are channels 1–8, 22, 23, 31–38, 41–48, 61–63 and 71–78. The reason is they’re reserved for specific uses. For example: Channels 5 and 35 are legislated for emergency use only and fines can be issued for their improper use. The maximum penalty for the misuse can be up to two years prison or $165,000 fine.

Channel 22 and 23 are reserved for telemetry and telecommand and can’t be used for voice. So, if your CB is fitted with a GPS, this is the channel from which it will send geo-location information to another CB that’s coded with the same tech. If not, stay off channel. Channels 61–63 are reserved for future allocation.

Other channels are reserved for repeater stations. Think of areas that are so large — or with undulating country — where talk on one channel simply can’t be heard by the intended recipient. The repeater station on a nearby mountain retransmits your conversation onto another channel that can be received at a location beyond your visual range.

Although there may be restrictions on channel use, there’s still plenty of bandwidth open for general use. The Channel Allocation table to the right shows which channels are available for recreational purposes. KEEP IT BRIEF While CBs are convenient, it’s worth remembering they use open channels, so, anyone can be trying to use the same channel you are.

Therefore, it’s important to observe some common courtesies. After all, this isn’t ‘open mike’ night at a comedy club where you get to ramble to an unwitting audience. A Golden Rule of CB etiquette is to keep it short and to the point. This can be a real issue because some people use their CB like a form of security blanket, constantly talking with their convoy about every insignificant observation.

The issue is the CB radio is often the only reliable means of communication on Australian farms, rural roads and highways. So, at any point, someone may have a greater need than you to use the bandwidth you’re monopolising. And the jackaroos and jillaroos on nearby properties aren’t interested in listening to you babble.

If someone breaks into your conversation, ask them to repeat what they said to determine if you need to give the channel over to them. If there’s too much competition for bandwidth on the channel you’re using, have a pre-arranged set of channels that you’ll move to, say 9, 39 and 79.

POTTY MOUTH Public profanity is an offence in every jurisdiction in Australia, be that at your local supermarket or on the airwaves. The problem of foul language exists among CB users and it gets worse the closer you get to the city. When it comes to talking on your CB, lead by example. If you hear inappropriate language, remind the offender that there are ‘ducks on the pond’ and to keep it clean.

In the main they will. While some will ignore you, others may simply have become careless with their language and your reminder may help reset their moral compass. For the one percenters who become aggressive or harassing, remember they are acting illegally.

If you have enough information (name, vehicle, rego or direction of travel), dial 131 444 to get the local Boys in Blue on the job. And for the truckie who just sounds like he needs a gentle kick up the butt from his boss, dial the phone number on the back of the rig to ‘Report my driving’. Avoid getting involved in caustic or threatening language yourself.

The kids in the car absorb your language, and lowering your own standards does no-one any good. Simply advise your convoy that you’re moving to your pre-agreed alternate channel. No need to tell the world what that channel actually is. Then stay quiet for 15 minutes so the offender can’t find you on an all-frequency scan.

  • TERMINOLOGY There are rules for radio communication and how we’re expected to talk and respond to each other.
  • Because only one person can speak at a time, each CB operator needs to know the rules.
  • For example, when you respond to a radio check, you need to do so in a way that provides relevant information and is easily understood by the transmitter.

So, consider providing information about your location, so the operator knows how far they’re transmitting. And tell them whether their voice is clear or distorted. For example, “Loud and clear from the Dog on the Tuckerbox” or “Weak and distorted, McDonalds Gundagai.” A response of “Yeah mate, gotcha” is not helpful.

When it comes to knowing what words and phrases to use, here are some common examples that you’ll hear. How many do you use correctly? Over: ‘Over’ means “I have finished speaking and expect a reply” (kind of like “it’s your turn now”). The use of this word is required by radiocommunications legislation and helps ensure you don’t ‘step-on’ another caller — in other words, that you don’t try to transmit at the same time as the person you’re trying to talk with.

Otherwise, both messages will end up garbled and no-one will know what’s going on. ‘Out’: This means “I’ve finished speaking and do not expect a reply”. This word should only be used by the person who initiated the conversation, not by other participants.

  1. It informs other users of the channel that you’ve finished, and they can have a conversation of their own.
  2. Over and Out’: This is a contradiction of terms and shouldn’t be used unless you want to sound like a dingbat.10-4: The phrase “10-4” comes from the ‘ten codes’ which originated in the Illinois police department in the late 1930s.

The codes were used as a form of shorthand where 10-4 simply meant ‘OK’ or ‘I acknowledge your last message’. Through the years, different government agencies started to generate their own unique codes. Ultimately, in 2005 when the US attempted a national response to Hurricane Katrina, there was monumental confusion among responders all using different codes.

As a result, the codes were killed off and plain speech now reigns supreme. Roger: This word comes from Morse Code. On receipt of a message, the operator would send back a single letter ‘R’ to indicate ‘Received’. When the invention of short-wave radios came along, ‘R’ was expanded to ‘Richard’. But, during the First World War, it changed to ‘Roger’ as it could be heard more clearly when spoken by Allied forces with different accents.

Roger Roger: Get caught using this and you’ll look like a dill to anyone in the know. It originally comes from a 1980’s comedy movie Airplane! and was a joke on radio communication etiquette with some sexual innuendo thrown in. The joke was re-cast in Star Wars: The Phantom Menace to signify someone’s acknowledgment of information when in reality they had no clue what was going on.

‘Roger Roger’ has no place on the short-waves. SOPS When you’re travelling with a team — be that in a convoy or with the entire family onboard — you won’t necessarily be together all the time. People go fishing, others duck into town and some just need some time alone. So you need to have systems because things can and do go wrong.

These are routinely called Standard Operating Procedures (SOPs). Different people will have an array of CBs on board too, like the 5W in-car/caravan radio or the 1, 2, 3 or even 5W handheld you’ll take on a bushwalk or give to the kids when they want to walk to the end of the beach 3km away.

  • Things like conducting radio checks don’t just let the other person know that you can hear them.
  • It also lets you know they’re safe, as do regular call ins.
  • Say someone is out walking.
  • Your SOP might be to have that person call every hour, on the hour.
  • The people with the handheld CB will not have the range of your in-car/caravan radio, but they might be able to receive your message.

If they’re not responding to your calls, you might ask them to press the pressel switch (PTT button) three times if they can hear you. This can be heard when you have the ‘squelch’ on, and you can hear the static. Their presses will break the silence. If they respond, you know they can hear you.

Or you could ask a series of questions of that group of fishers who left this morning, like, “Are you OK.” One long press of the switch for ‘no’ and three short presses for ‘yes’. Your CB is more than a way to chit chat with the car in front of you, it’s a safety device.

  1. Clarity: Your voice should be clear and a little slower than normal. Speak in a normal tone and do not shout as the microphone will amplify your voice.
  2. Simplicity: Keep your message simple for intended listeners to understand. They might not know all the CB lingo you do.
  3. Brevity: Keep your message short and to the point.
  4. Security: Do not transmit confidential information (names, addresses, or where you leave your keys, etc). Remember, frequencies are shared, so you do not have exclusive use of the channel.

What is code Eleven?

From Wikipedia, the free encyclopedia ” 0123452 ” encoded in Code 11 Code 11 is a barcode symbology developed by Intermec in 1977, and it is used primarily in telecommunications. The symbol can encode any length string consisting of the digits 0–9 and the dash character (-). A twelfth code represents the start/stop character, commonly printed as “*”.

  • One or two modulo-11 check digit(s) can be included.
  • It is a discrete, binary symbology where each digit consists of three bars and two spaces; a single narrow space separates consecutive symbols.
  • The width of a digit is not fixed; three digits (0, 9 and -) have one wide element, while the others have two wide elements.

The valid codes have one wide bar, and may have one additional wide element (bar or space).

The decode table has 15 entries because the symbols with two wide bars (1, 4 and 5) are listed twice. Assuming narrow elements are one unit wide and wide elements are two units, the average digit is 7.8 units. This is better than codes with a larger repertoire like Codabar (10 units) or Code 39 (11 units), but not quite as good as interleaved 2 of 5 (7 units).

What does 10-1 mean in slang?

WHAT DOES 10-1 MEAN ON A FILM SET? – On a film set, 10-1 is the walkie talkie code for the bathroom.

What does 10 20 mean?

What’s Your 10-20? One of the questions we’ve been asked most often over the past month is “what does 10-20 mean”? It’s a question that can be answered easily, actually. We took inspiration from CB Radio slang. In fact, the following is from If you hear a truck driver say “10-20” on their CB radio, it’s just another way to say “Your current location.” And offers a little more history: The phrase essentially means, “What is your location?” or “Identify your position,” but is a corrupted phrase from the original “10-20” used by law enforcement to verbally encode their radio transmissions so that non-police listeners would not easily discover police operations, as well as to communicate quicker and more efficiently by standardizing frequently used phrases.

These verbally-coded messages were called “10 codes”, of which “10-20” stood for “Identify your position,” or “Where are you?” originally. Other such codes include “10-7” meaning the officer was busy such as with a traffic pull-over, “10-8” meaning that the officer was back on patrol such as from having just written a citation, the popular “10-4” as an affirmative, “10-10” as a negative and “10-22” to disregard a previous transmission have only seen light integration into common use.

It was not uncommon for a city to have its own set of particular 10-codes for other phrases frequently used particular to that locale. So that’s where we took our inspiration from. More importantly, though, is ensuring that your 10-20 is protected online.

And by that we mean that your location, your brick and mortar address, should be claimed and consistently presented across a number of search engines, review sites and mapping technologies. Why? Because when someone searches for your business or keywords associated to it, you’ll have a greater chance of turning up on Google, Bing, Yahoo, Yelp, Facebook or Tom Tom, to name a few online listing technologies.

And in today’s local search-driven economy, being able to pinpoint your location on the maps and search engines that drive the small business economy is not just good practice, it is critical to the survival of your livelihood. Because if your small business doesn’t show up as a search engine result, your competitor’s will.
