10-Codes
One example of codes used by Law Enforcement is the "10-code." The 10-code allows police to relay information over the radio quickly, assigning numbers to certain things or actions. All begin with "10," but the number that follows will have a particular meaning. Some examples of 10 codes:
10-4: I am ok or I understand
10-6: Busy
10-8: Clear
10-9: Repeat last transmission
10-27: Driver's License check
10-28: Vehicle registration check
10-55: Drunk driver
10-96: A person with mental problems
10:99: A wanted person-active arrest warrants
The 10-code goes all the way up to 10-100 and uses almost every number between 0 and 99. (See the Official Ten for a complete list of 10-codes.) It is much easier and a lot quicker for an officer to say "10-27" than "I need you to run a drivers license check." It is also much easier for a dispatcher to understand this abbreviated message, with much less likelihood of miscommunication.
