FiRST Radio IDs


Unit Ids

The section that previously existed here identifying RID ranges for multiple Maryland, federal, county, and out-of-state agencies on multiple systems has been moved and merged here.

For all lists below: Agencies are listed alphabetically. Labels are organized by sequential numeric RID. This list will be drawn-down for agencies that do not carry vehicle-specific portable radios, as there tend to be no consistent unit IDs for those agencies (Maryland State agency IDs tend to be vehicle plate numbers). Sequence/badge IDs will not be included in the event they issue take-home radios. Please include in these categories all system-specific information for these agencies.

A list of all radio ID ranges in the State of Maryland can be found at the Maryland Statewide Trunking Interoperability Page.

Maryland Transportation Authority (MdTA)

MdTAP Patrol Division issues take-home portables (2116600-2117251): these are being drawn down as they are confirmed. MdTAP mobile radios have been recorded in the 2117600-2117900 series. MdTAP Special Operations units (SOD, K9, CV) appear to have assigned/take-home vehicles. Thus, portable IDs will match vehicle/post numbers.

MdTA Unit Prefixes are:

  • B = BWI Airport Detachment
  • H = HATEM Bridge Detachment
  • I = ICC Detachment (MD 200)
  • K = KEY Bridge Detachment
  • P = PORT of Baltimore Detachment
  • T = FMT McHenry and Harbor Tunnel Detachment
  • L = WP Lane BAY Bridge Detachment
  • CV = Commercial Vehicles Unit
  • TC = Tunnel Command (Vehicle Plate Designations for FMT)
  • HQ = Headquarters
  • K9[#] = K9 Units
  • SOD = Special Operations Division
