'''Ten-codes''', or '''10-codes''', are used in two-way voice [[radio]] communication as verbal numeric shorthand for frequently used messages. They originated in the [[United States]] law enforcement community before the second [[World War II]]. There is no universal, official set of 10-codes, and the meanings of a particular 10-code can vary between one jurisdiction and another: a code meaning "I have the suspect in custody" in one state can mean "Send an ambulance" in a second state and have yet another meaning in a third.
