Radio Communication Codes For Walkie-Talkies

Police Officer Using Radio

I think most people are familiar with the usage of radio codes in movies, who hasn’t heard some cop character utter the phrases “10-4” or “roger wilco”. In this article I will provide some background so you can use these radio communication codes with your own walkie-talkie.

Radio communication codes are used to clarify, simplify and standardize communication over two-way radios such as walkie-talkies. These communication codes are short phrases that can easily be understood by receivers and thus reduce misunderstanding. Everyone can use these codes, but they are mostly associated with law enforcement agencies such as the police.

The most well-known radio communication codes are the ten-codes. There are other communication codes in use, such as Q codes in amateur or ham radio and aviation, but I will not focus on these in this article as they are not so widely known.

Ten-codes

As said before, ten-codes (also 10-codes) are the most well-know radio communication codes. The ten-codes are code phrases that can be used instead of common phrases in radio communications. The word ten is used to indicate that the next number is a code, which makes it easy to recognize these codes.

The ten-codes were standardized by the Association of Chief Police Officers in the past and used by law enforcement agencies and civilian CB radio users. However, over time different agencies used different meanings for the codes which actually undid the usefulness of the standardized radio codes.

This became particularly clear in the aftermath of hurricane Katrina in 2005 where there were several instances of inter-agency communication problems. After that Federal Emergency Management Agency (FEMA) actually discouraged the use of ten-codes and advocates the use of plain everyday language for radio communications.

But if you are using your walkie-talkies with friends or family it can still be fun to use these codes. So in the remainder of this article I will list the codes used by the police, so you can start using them yourself right away!

Police codes

I divided the codes used by the police in three categories: 10-codes, 11-codes and Hundred codes.

The 11-codes, or “eleven-codes”, are not used as often by the police as the 10-codes and are only used in certain areas. They are designed to facilitate the communication between police officers and police dispatchers.

The Hundred codes are three digit code used by the police to indicate certain types of crime. These codes are usually pronounced digit-by-digit, for example 187 as “one eight seven”.
