Police codes were developed during 1937–1940 and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO).
The most used police code used is when an officer retires a call to dispatch is made. The officer gives a 10-7 code (Out of service) and then a 10-42 code (ending tour of duty).
APCO first proposed Morse code brevity codes in the June 1935 issue of The APCO Bulletin, which were adapted from the procedure symbols of the U.S. Navy, though these procedures were for communications in Morse code, not voice.
