Ten-codes are used for quick and surreptitious communication. There will be some differences from jurisdiction to jurisdiction, but these are the basic codes. Some organizations and municipalities also use other codes in addition to the ten-codes. An example is the California Highway Patrol's use of eleven-codes, and the New York/New Jersey Port Authority Police Department's use of eight codes.
