A Brief History of Police Codes

Police radio codes, including EXP, trace their roots back to the late 1930s. The system was originally developed between 1937 and 1940 and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO). These codes were designed to make voice communication more efficient, reliable, and standardized across departments.

Interestingly, the first iteration of radio brevity codes proposed by APCO in 1935 took inspiration from the U.S. Navy’s Morse code procedures. Though initially meant for Morse-based communication, these codes evolved to accommodate voice transmissions, becoming a critical part of police radio protocol.

Over the years, codes like 10-7 (Out of Service) and 10-42 (Ending Tour of Duty) became standardized nationwide. Similarly, codes such as EXP (Expired) continue to play a vital role in ensuring law enforcement operations run smoothly and safely.

EXP Police Code – Why It Matters

Using codes like EXP allows officers to save time and reduce the chance of error during high-pressure moments. Imagine trying to describe an expired vehicle registration or permit during a high-speed pursuit or a traffic stop—it’s much faster and clearer to say “Code EXP.” This shorthand approach eliminates ambiguity and enhances field communication.

Whether you’re a law enforcement professional, a researcher, or a civilian hobbyist using a police scanner, understanding the EXP Police Code and other signal codes can give you deeper insight into the language of emergency response.
