Police Scanner Ten Codes

What are Police Scanner Ten Codes?









These codes are used to replace actual words or phrases used in radio communications. They are often used by police and fire departments. In most cases, they are used in ambulances during emergencies. Those involved in rescue operations during disasters also use them. Among popular police scanner ten codes is 10-4. It means a radio message or signal is received loud and clear.

Why Ten Codes?

There are some dozens (not just ten) of police scanner ten codes generally in use today. They are all prefixed with the number ten. Hence, the term ten codes. Ten was chosen way back in 1937. It was the time when radio communication codes began to be used. This was to hasten police reporting through radio and remedy the problem of radio static. The first few seconds of transmission was blurred by static. Hence, to make sure messages were not affected by it, a preliminary code 10 was first sent immediately followed by the main code.
