10-1

Government & Politics abbreviation · Police Code

10-1 stands for Receiving poorly, a police code abbreviation.

Radio code telling the other party that their transmission is weak or unreadable, suggesting they change location or try again. On the APCO list it reads "unable to copy, change location."

Example: Unit 7, you're 10-1, try again when you clear the underpass.

Usage notes

Poor reception is common in valleys, buildings and dead zones, and modern digital radio systems have their own coverage gaps. Many agencies now simply say "unreadable" or "say again." Like all ten-codes, its meaning can vary by department.
