Instructions:

• Type in a callsign using either the QRZ, HamCall, or ARRL search engine input boxes.
• Hit the [Enter] button or [Enter] key on your keyboard (for QRZ or HamCall only).

Why use this page rather than going direct to the servers?

• You can lookup several callsigns without having to hit the "backup" button on your browser. Just enter a callsign, hit [Enter] (for QRZ or HamCall) or hit the "Submit" button for the ARRL lookup.
• There are three callsign databases to use from this one frame. If you can't find the callsign at QRZ, try HamCall, or ARRL.

About the Callsign Search Engines

• QRZ -- U.S. and and many international callsigns. Very much up-to-date with the latest FCC changes and a good starting place for any callsign lookups.
• HamCall -- The first to put callsigns on CD. Buckmaster's database is very complete. This "points" to the International callsign database, but you can lookup U.S. callsigns here too.
• ARRL -- This is used to lookup recent changes, either by Name or Callsign. If you enter a Last Name (and optionally a first name) the Callsign field is ignored.
