What Does Police Code 10-26 Mean?

History and Origin of Police Radio Codes

The use of police radio codes dates back to between 1937 and 1940, when law enforcement agencies began to adopt a more standardized way to communicate quickly and clearly over radio channels. In 1974, the Association of Public-Safety Communications Officials-International (APCO) expanded and refined the list of ten-codes to support modern policing efforts.

Interestingly, the concept of coded communication in public safety has roots in the 1935 APCO Bulletin, where Morse code brevity codes were introduced. These codes were inspired by procedures developed by the U.S. Navy—though they were originally designed for Morse code communication rather than voice transmission.

Most Common Police Codes in Use Today

One of the most recognized police codes is 10-7, which means “Out of service,” often used when an officer ends their shift or leaves active duty. Another frequently used code is 10-42, which signifies “Ending tour of duty” and is sometimes used during ceremonial or final sign-offs.

These two codes—10-7 and 10-42—carry significant emotional weight and tradition in law enforcement culture, especially during retirement announcements or tributes to fallen officers.
