California Penal Code sections were in use by the Los Angeles Police Department as early as the 1940s, and these Hundred Code numbers are still used today instead of the corresponding ten-code. The best-known include:

• "187": Homicide Further information: 187 (slang)
• "211": Armed Robbery
• "415": Disturbance
• "417": Person with a gun
• "502": Intoxicated Driver
• "5150": mentally disturbed person (actually a reference to the California Welfare and Institutions Code)

Generally these are given as two sets of numbers—"One Eighty-Seven" or "Fifty-One Fifty"—with a few exceptions such as "459"—Burglary, which is given as "Four-Five-Nine".

The New York Fire Department uses its own ten-code system

The New Zealand Fire Service uses a system of "K-codes" to pass fire appliance availability statuses as well as operational messages. The New Zealand Police also use some K-codes, with completely unrelated meanings to those used by NZFS. For example, the NZFS code "K1" means "proceeding to incident", while the Police code "K1" means "no further police action required". The New Zealand Coordinated Incident Management System uses the same common language as the Incident Command System to avoid inter-agency confusion.

The California Highway Patrol uses eleven-codes.

Q code and prosigns for Morse code are used in amateur radio, aviation and marine radio. They provide specific abbreviations for concepts related to aviation, shipping, RTTY, radiotelegraph and amateur radio. In radiotelegraph operation, a Q code is often shorter (as ten-codes require transmission of three prefix characters: 1, 0, hyphen) and provides standardization of codes, essential in international and shortwave communication.

Z codes are used by NATO countries in military radio communications.
