Police Communication Codes

Police, fire and ambulance personnel use a large body of acronyms, abbreviations, codes and slang to provide quick concise descriptions of situations in both spoken and written communication. This jargon has grown into a vast language that is colloquially referred to as “cop talk” by radio scanner enthusiasts and other professionals that work in conjunction with these agencies. The following information and additional resources are provided in hopes of easing the pain of translating the cop talk commonly used in the Public Safety records we publish on Narconon Reviews.

Understanding Public Safety Jargon

Despite multiple attempts by the APCO to define a national standard for the most commonly used police codes over the past seventy-five years, substantial variations exist between local, county and state agencies. For anything beyond the first 2-3 dozen basic 10 and 11 codes, proper translation of police reports and dispatch records obtained via Open Record Requests requires a “cheat sheet” or glossary for the average layperson. There is also a long-standing tradition of some police agencies being resistant to releasing the specific list of radio codes they define internally for security reasons.

Whenever possible, this website will provide documentation obtained from a given agency for translating the numeric codes that frequently appear in the disclosure files posted here. Currently, we have the following cheat sheets readily available for cross reference look-ups to the public safety records we have archived.

  • (Editor’s note: additional resource pages will be listed here eventually)

When in-house documentation from a given agency is not available, the Generic Cop Talk Glossary listings below can be used for approximate translations. Before relying on the listings provided on this page, we recommend you check the websites we have indexed under Additional Reference Lists as well as your favorite search engine for a list of “police codes” for the specific agency, municipality and county/state you are trying to translate.

If you are unable to find a list for the exact agency or area, adjacent areas are the next best thing since neighboring station houses tend to standardize with each other when they share personnel and responsibilities within a broader community. When all else fails, use our generic glossary with this disclaimer: for every code or abbreviation correctly translated here, there will be a dozen or more brevity codes that are completely unique to the agency or area that we are missing or have listed incorrectly.

Generic Cop Talk Glossary

The following outline is a partial list of codes and abbreviation that may or may not be used by a given agency. We have limited this listing to commonly used codes specifically related to the open record requests we publish. While some normalization exists for 10/11 codes and other acronyms, the 2 and 3 digit brevity codes can be derivatives of local ordinances, state penal codes and/or seemingly random numbers chosen simply because they didn’t sound similar to anything else commonly used.
