Codes and Lingo


Due to the nature of emergency services and 2-way radio communications, most agencies have adopted specific codes to identify calling parties, statuses, incidents, and various situations. It's not always easy to pick up on the style of communications and radio lingo - it takes time and experience to piece things together quickly.

We've included some basic radio procedure for the local agencies on this page. Once you’ve familiarized yourself with the radio communication protocols, if you hear a term that you are unfamiliar with, you may wish to check the glossary to see if it is defined there.

If you notice that any of this information is out of date or incorrect, please let us know by sending us a note on our contact page. Thanks!



Due to static and less-than-perfect transmission conditions, most spellings done over radio are done phonetically - in other words, a standardized word is said in place of each letter. For example, if a unit were calling in a person with the last name of "Smith", it would usually be transmitted as "Sam Mary Ida Tom Henry". Law enforcement phonetics are generally different from military and amateur radio phonetics.

Standard Law Enforcement Phonetic Alphabet:

A Adam    N Nora
B Boy or Baker    O Ocean
C Charlie    P Paul
D David    Q Queen
E Edward    R Robert
F Frank    S Sam
G George    T Tom
H Henry    U Union
I Ida    V Victor
J John    W William
K King    X X-ray
L Lincoln    Y Young or Yellow
M Mary    Z Zebra


Unit Designators

Unit designators are generally used to determine the type of police unit calling into dispatch (and can determine officer rank, vehicle type, special assignment, or other special notations. The designator precedes the unit's ID number. If the designator itself is preceded by a number (such as 1-Adam-85), that number indicates the patrol area (beat) for the officer.

Please note that several of these are incredibly out of date and haven't been used since 2012-2013 for many agencies.

Status, Disposition, and Informational Codes

Status, disposition, and other informational codes are often used to quickly convey information over the radio. Grants Pass Public Safety and the Josephine County Sheriff's Office both use mostly plain-text radio communications with the exception of a small number of status/info codes. OSP utilizes 12-code for most communications as well as numerous disposition codes when clearing calls.
