DU-COMM Police Agency IDs and Codes

DU-COMM police agency radio IDs are formated as SHIFT+AGENCY+ASSIGNMENT (as in 1Tango1). 1Tango1 would be the dayshift Wheaton PD unit in beat 1. Some officers don't use the shift identifier (as in Tango 1). Units that have permanently assigned radios IDs (some CSO's, admin staff, detectives, etc.) just use the AGENCY+ASSIGNMENT format (example: Echo 71 is always the Elmhurst PD deputy chief or admin division commander, etc).

The assignment numbers are generally as follows:

• 1-18 are beat cars

(generally the odd numbers are north, even numbers south)

• 19 is the desk
• 20-29 are cover/citywide cars
• 30-39 are supervisors
• 40-49 are either traffic units or CSO's
• 50 is the detective commander
• 51-59 are detectives/investigators
• 60-69 are department defined (sometimes these are gang or tactical units)
• 70 is the chief
• 71-79 are command staff
• 80-89 are department defined (sometimes these are mall or college liason unit)
• 90-99 are CSO's, parking, etc.
• 100+ are generally aux. police
