Our Police Code Lookup page is a quick-reference tool for public safety radio traffic—built for scanner listeners, dispatch monitoring, and anyone who deals with emergency communications.

It covers common police 10-codes, signals, and dispatch shorthand used across agencies in the U.S. Keep in mind: not every department runs the same system. What means one thing in one county might mean something completely different two towns over. Use the search to look up codes as you hear them over the air, or browse by system if you're digging through how different agencies structure their traffic.
