Hamtrax Can't Find My Callsign

Your license is real — but no single lookup source lists every ham in the world. Hamtrax checks FCC data plus multiple global callbooks. Coverage is excellent for the US and strong for most of Europe, Japan, and Canada, but some countries do not publish machine-readable registries, and a newly issued callsign can be active in the official registry before the sources Hamtrax currently has available have refreshed.

If signup says Lookup couldn’t finish. Tap the callsign to try again., tap the callsign field to retry. That message means the network or lookup service did not finish — it does not mean the license databases rejected your callsign.

If the lookup can't confirm your callsign, here's the path forward:

1. Double-check the callsign​

The classic culprits: the letter O vs the digit 0, the letter I vs the digit 1, or a missing digit. Every valid callsign contains at least one letter and one number.

2. Continue without it — you lose nothing​

Choose I don't have a callsign yet and finish creating your account. Your account is complete and nothing is thrown away. Logging contacts and spotting POTA activators require a valid saved callsign, so add it as soon as the lookup can find you.

3. Add it later — from Settings, or from wherever Hamtrax asks​

Go to Settings → Account and enter your callsign there — it runs the same lookup. You don't have to make a special trip, either: the prompt that appears when you log a contact, add one by hand, import a logbook, or tap Heard to spot a POTA activator is the same field with the same lookup, and saves without taking you away from what you were doing. Add it in Settings instead on that prompt brings you here when you'd rather.

Wherever you enter it, the rule is the same: only a callsign the lookup confirms is saved. If your license is new, try again after a few days because lookup sources refresh on different schedules. If the official registry already shows the callsign as active, skip the step and send it through Feedback so we can investigate a Hamtrax source or update lag rather than treating it as your mistake.

4. Still not found? Tell us so we can investigate​

If your callsign is active but Hamtrax still can't find it, open Feedback in the app sidebar — its own row below Tools — and send us the callsign. We'll review whether Hamtrax's lookup sources or update process are behind the official registry.
