Brevity codes are lists of short coded messages -- 10-codes, 9-codes, signals, Q-codes, and the like -- which are used in voice radio communications for three main reasons:
- they shorten transmissions,
- they obscure meaning from the General Public, and
- they provide users with a convenient dictionary of messages, such that everyone's working off the same sheet of music.
The latter of those three may well be the most important use of brevity codes, though it's rarely mentioned, and often not obvious even to regular users. When using a brevity code on the air, a police officer, paramedic, or street sweeper doesn't need to think about how to say what he wants to say, or what the message means; that part's been taken care of already.
The problem with brevity codes is the same as the problem with standards: there are so many of them -- this wiki carries many lists of them, promulgated by various authorities, all slightly different; more are on the web at large.
Because of this, the National Incident Management System had originally planned to forbid their use in the communications concerning any event managed by its Incident Command System process. That plan met the resistance you might expect from local agencies when it was announced, and they've since retreated from that position.
But the problems they identified with everyone having their own code list are still real, practical problems, which still need a real solution.
In any event, having lists of these codes makes listening to such communications easier and more fulfilling -- and sometimes more practically useful; not all scanner listeners are just doing it for fun.

Lists of Brevity Codes
Many lists of brevity codes are already on the wiki; please add links below that point to the pages (or preferably directly to sections on a page, where applicable) with lists you are aware of. If you add a list, please put it in an appropriate geographic or agency article, or its own article if none exists, and then link to it from here. When adding a new list, please try to pin down *precisely* which agency's list it is, and designate the page or section appropriately. Links to external lists are fine too; look at some of the sections below to see how such links are formatted.
