In June 1935, APCO had initially proposed brevity signals adapted from U.S. Navy Morse code procedures, which eventually evolved into the voice codes we recognize today.

The Ten-Codes, like 10-7 (Out of Service) and 10-42 (Ending Tour of Duty), are also part of this communication system, ensuring quick and consistent exchanges across various scenarios. Over the years, codes like Code 33 have become vital tools in emergency response workflows.
