A Deep Dive into the History of Police Ten Codes

Police radio codes, also known as ten-codes or signal codes, were first developed between 1937 and 1940 to create a standardized method of communication for law enforcement. The system was later refined and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO). Originally inspired by Morse code brevity procedures used by the U.S. Navy, the APCO ten-code system enabled faster, more efficient communication in the field, especially under high-pressure or life-threatening situations.

For example, when a police officer goes off-duty, they might sign off with a 10-7 code (Out of service) followed by a 10-42 code (End of tour of duty)—a respectful acknowledgment of a completed shift.
