|A 10 code is any one of the communication codes starting with 10, often used by both government and private institutions to provide a basic framework for communications in the facility. 10 codes are implemented by giving employees a Two-way Radio which they can use for communication between the control center and each other.|
10 codes are not regulated and are often adapted by corporations to suit their needs and wants, however the most basic ones to tend to stay the same.
One of the main reasons a Urban Explorer would want to carry a list of 10 codes with them is to listen in to security, police, fire, EMS, maintenance, or general communication frequencies and gather information. A typical conversation may go as follows, with persons signified as letters:
A: 635 to 638.
B: 638, go ahead.
A: 10-34 south entrance ground, multiple 10-12.
B: Roger, 10-6.
B: 291, 10-200 south entrance ground level.
C: 638, 10-4, notifying.
To an unprepared listener this may sound like gibberish, but to someone armed with the knowledge of 10 codes this can provide a wealth of useful information. Let's see what it would look like if this was spoken in plain English:
A: 635 to 638.
B: 638, go ahead.
A: Trouble at south entrance ground level, help needed, multiple visitors.
B: Roger, please stand by.
B: 291, police needed at south entrance ground level.
C: 638, got that. Notifying cops.
In this situation the knowledge of the 10 codes may mean the difference between getting out of there and getting busted.
Here's a list of the most commonly used 10 codes. Please note that while these do vary company to company, a lot stay the same.
(EDIT 3/16/07): The above paragraph is NOT factually accurate. 10 codes vary widely from department to department, county to county, state to state. The below should NOT be used as a reference. Use the internet to search for the organization's 10 codes you are looking to decode.

10 codes list from http://archimedes....raiar/code-10.html.
To keep the thread short I'll only post the link. I've found that many jurisdictions use different 10 Codes. Those found at this link are more applicable to police use: http://www.phreak.org/radio/tencode.html
Addendum: Many departments and organizations throughout the United States and Canada are ELIMINATING the use of 10 codes entirely. This is because as radio systems focus on interoperability (the ability for two or more dissimilar radio systems to communicate), it is not efficient for organizations to use 10 codes any longer as each organization uses different 10 codes. 10 codes will likely become a thing of the past, sooner rather than later.
