Police Scanner 10 Codes

Police use the 10 codes to simplify an event into a number. It’s much easier and more clear on a police radio to say 10-7 rather than ‘out of service’, especially when radio transmissions can be garbled or hard to understand.

I’m not sure if all police departments still use these codes, due in part to digital radio transmissions making conversations far more clear. In any case, if you’re listening to a police scanner in an area where the police still use the 10 codes, the universal list is shown below:
