Brevity codes are used in amateur radio, maritime, aviation and military communications. The codes are designed to convey complex information with a few words or codes. Some terms are classified to the public.

Brevity codes

  • ACP-131 Allied military brevity codes
  • Multiservice tactical brevity code used by various military forces. The codes' procedure words, a type of voice procedure, are designed to convey complex information with a few words, when brevity is required but security is not.
  • Ten-code - North American police brevity codes, including such notable ones as 10-4.
  • Phillips Code

Operating signals

Operating signals are one type of brevity code wherein the signals are designed and used primarily to support the communication of the communications (radio and telegraph) operators among themselves with respect to communications operations, instead of communicating abbreviated messages about non-communications related activities.

  • 92 Code Western Union telegraph brevity codes
  • Q code - initially developed for commercial radiotelegraph communication, and later adopted by other radio services, especially amateur radio. Used since circa 1909.
  • R code - published by the British Post Office in 1908 for use only by British coastal wireless stations and ships licensed by the Postmaster General.[1]
  • S code - published by the British Post Office in 1908 for use only by British coastal wireless stations and ships licensed by the Postmaster General.[1]
  • X code - used by European military services as a wireless telegraphy code in the 1930s and 1940s
  • Z code - also used in the early days of radiotelegraph communication.
