The Evolution of Police Signals

These Morse-based systems evolved into the voice-based 10-codes we know today, forming a critical part of American law enforcement communication standards.

More Than Just 10-91

While the 10-91 Police Code is one of the many essential codes used nationwide, officers rely on dozens of others every single day—from 10-4 (Acknowledged) to 10-42 (End of Duty) and 10-7 (Out of Service). Each code serves a specific function in maintaining order, efficiency, and clarity in critical, time-sensitive situations.
