Revision as of 04:23, 30 December 2005
Ten-codes, properly known as ten signals, are code words used to represent common phrases in voice communication, particularly in radio transmissions. The codes, developed in 1937 and expanded in 1974 by the Association of Public Safety Communication Officials (APCO), allow for brevity and standardization of message traffic. They are widely used by law enforcement officers in North America.
Some municipalities also use other codes in addition to the ten-codes.
Ten-codes were adapted for use by CB radio enthusiasts before its pop culture explosion in the late 1970s, thus many of the phrases, such as 10-4 and "what's your twenty" have entered everyday use in the English language. A popular fictional account of ten-codes in use among CB-communicating truckers may be heard in the 1978 movie Convoy.
In the fall of 2005, responding to inter-organisational communication problems during the rescue operations after Hurricane Katrina, The United States Federal Emergency Management Agency (FEMA) discouraged the use of ten-codes and other codes due to their high variability in meaning (see the November 2005 articles in External links, below).
List of 10-codes
The following list illustrates the current usage of various 10-codes. Only a handful of them are standardized. Some are fairly consistent, while others (such as 10-40) can have completely different meanings, many of which are not listed here. Multiple meanings for the same code are set apart by semicolons.
The first bold definition is the current APCO specification, a standard that has been adapted by most law enforcement agencies. Popular alternate meanings follow in bold, while less common meanings are in regular typeface. Meanings specific to CB radio are set in italics.
This is not a complete list, but is intended to show some of the most common codes and help provide an estimate of what a code's definition is. A search for local ten-code tables should be performed first before using this chart.
