Utah Communications Authority P25 RID/UID Reference

This page is a place for everyone to document radio/user IDs encountered on the Utah Communications Authority P25 statewide radio system, with the goal to help ID new talkgroups.

How Initial RIDs Were Determined

Radio labels and IDs being transmitted via the control channel

The initial dataset included in this page is not inclusive - it is a collection of scanning a singular site on the new statewide P25 system using SDR Trunk and a couple of software defined radios (SDRs).

Harris radios will broadcast the actual name/label of the radio on the system when a user turns on the radio or joins a talkgroup. This data is encoded (but not encrypted) in the control channel datastream, and software like SDR Trunk can decode, extract and display this information. In most cases, these labels contain the agency alphanumeric ID - one or two numbers, followed by a letter. By logging these radios, patterns started to appear, and data was compared to already-identified talkgroups and cross-referenced with the Utah State Agency Radio Callsigns page.

Some labels are not always correct - for example, radios labeled for one fire engine or ambulance may end up being installed in another. In some cases, there is no label information whatsoever; only a string of random numbers or the numeric radio ID itself. They should not always be considered 100% accurate.

Your help is needed in determining unknown RID blocks, as well as adding new ones to this list!

Note: While SDR Trunk or other trunk-tracking software would be recommended, especially for logging large amounts of data, you do not necessarily need SDRs to help ID RIDs - most (if not all) scanners have the option to display the RID on key-up.

Radio ID Nomenclature

All Radios have an eight digit ID. The first four digits indicate the block which has been allocated to an agency. The second four digits are used to identify the specific radio.

Take the RID 14670136 for example:

• 1467 is the block allocated to the City of Lehi in Utah County
• 0136 is the radio ID. Note that because radios are assigned to a jurisdiction instead of individual agencies within the city, it is impossible to know if this is a fire/EMS radio, a police radio, or perhaps in an emergency management cache.

As of December 2024, an agency may have up to 10,000 radios in one block. This may change as time goes on, cities grow, agencies added, and so forth. And radio ID blocks DO NOT OVERLAP WITH OTHER BLOCKS! Very important!
