Gaming Aid - Police 10 Codes

Here's a handy little resource for games where the players take on roles of police officers.  The radio codes commonly used by law enforcement agencies.  Do take note that there are variances between different offices and some even use a code of their own design.  Using this during play helps create atmosphere and aid immersion.  This list was provided to me by a long time friend and game master.

A 10 code is a number designation to an event or message that is commonly used by the police departments of the United States. This helps quicken message transmission and also makes it harder for someone to understand whats going while listening to police band. This gives the police an edge in the fact that most people will not know where the units are or what they are currently doing. The following is a list of the police 10 codes commonly used in the fictional Transea metropolitian area.

In addition to the use of 10 codes, most police forces have a designated second channel they switch to when they need to transmit personal information or have a more informal conversation. Most or the time the number designation of the channel is not the actual channel they are going to. Ex: the call sign to switch to the other channel my be 'Swith to channel 5' where as they actually switch to channel 7.
