License Search, 800MHz Reconfiguration Search

The 800 MHz Reconfiguration Search allows you to search for licenses that are no longer in the Public Safety region. You can specify to search only for call signs, locations, vacated date, or frequencies that match your specified criteria.

The Reset button will clear all the criteria you have chosen below to start a new search. The Search button activates a database search based on the criteria you have chosen below.

Call Sign

You can search for a specific former call sign. A call sign is a combination of letters and numbers that identify an FCC license.

Geographic Search Criteria

You may choose to search only within a specific geographic region. In addition to searching by Call sign, Region Close Date, and Frequencies, you may specify one geographic criteria in your search: Public Safety Region, State/County, or Coordinates. Please be aware that searching on multiple states or counties may result in slower search results.

Public Safety Region

Use the dropdown list to restrict the search to only the selected Public Safety region.


Use the State and Country fields to search only within the specified county. Use the dropdown list to select the state and the corresponding counties will appear in the County(s) field. Select the county(s) that are displayed.


Use the Coordinates field to search only within the specified coordinates. For both the Latitude and Longitude coordinates, enter the degrees, minutes and seconds. For the Latitude coordinates, select either North or South. For the Longitude coordinates, select either East or West.
Region Close Date

Enter the starting and end date if you want to restrict the search to your specified date range.


You can choose to search All Frequencies, an exact frequency in megahertz, or a range of frequencies in megahertz.

Note: Frequencies in a Terminated status are not retrieved when searching by Frequency.

Search Results

The ULS Search Results page is created for you each time you submit a search. The top of the page displays the search criteria you used in your Vacated Spectrum search. The number of matches to your search criteria is also displayed. If more than one page of data has been returned, a Numbered Index of links to additional results pages is displayed, along with a Next and Previous button as needed. Searches may return a mixture of licenses and leases.

Added Functionality
