USING COMMON 10-CODES

Citizen's band operators have largely
adopted the following 10-codes for stan-
dard questions and answers. These
codes permit faster and more precise
communication in noisy areas. This ta-
ble lists codes adopted by the Associat-
ed Public-Safety Communications
Officers (APCO).

Note: Although this table lists the 10-
codes’ meanings in the form of a state-
ment, they can also be phrased as
questions (10-6: Are you busy?, 10-20:
What is your location?).
