Enter only one data type per request:
Call Sign: Enter the exact call sign without any 'portable' indicators (example: KU3N is OK but KU3N/7 will not work).
Previous and expired call sign data is limited to what is in the FCC's ULS database.
By City (mailing address): Enter the community name in the first field and the two-letter postal state abbreviation in the
second field. If you are unsure of the spelling, you can enter the first three letters of a community name and
it will try to find it for you. This is based on the amateur's mailing address and not necessarily their physical
By Last Name: Enter the last name of the licensee. You can narrow it with a comma, space and the first initial or name
(e.g. BRADLEY, M) but keep in mind, ULS does not everyone in a perfect format. Sometimes, a suffix (e.g. Jr, Sr) may get
in the way. FCCdata will only return the first 500 matches of a query. Keep that in mind when entering data.
