| State of Wisconsin Project 25 Unit Identification Plan |
| "We get paid to break the law." |
The State of Wisconsin has established this plan for Project 25 digital radio unit IDs. This is the identification number that is programmed into the radio and can be decoded by receiving units. The purpose of this plan is to provide a logical plan for the assignment of unique radio identifiers to all potential Project 25 digital capable radios used by public safety agencies within the State of Wisconsin. The goal of the plan is to eliminate use of duplicate identifiers and maximize the benefit of the imbedded unit ID capability through the use of a number that is logically defined. This number can be tied to an alphanumeric display.
The unit identifier consists of 7 numbers (in decimal format):
A & B: The first 2 digits will denote the county that the radio is based in or, for state and federal radios, the agency that owns it.
- 01-72: Wisconsin Counties - Standard Numbering
- 73: Milwaukee County Transit System
- 74-79: Reserved
- 80: Non-Governmental Organizations
- 81-90: Wisconsin State Agencies
- 91-99: U.S. Federal Agencies
C: The third digit is an optional prefix to differentiate between radios within a county that have the same unit number or radio call number, such as a mobile and portable assigned to an individual officer, or type of agencies.
- 0: Default or mobile radio
- 1: Portable radio
- 2: Control station or third radio assigned to an individual or unit
- 3: Fixed stations/bases/consoles/other
- 4-9: Optionally used to differentiate between duplicate unit IDs used by different agencies within a county
- 4: Police
- 5: Fire
- 6: EMS
- 7: Emergency Management
- 8: DPW
- 9: Local Government/Non-Governmental/Other
D, E, F, & G: The unit ID of the vehicle, officer or person that the radio is assigned to, or the radio.
