How to Use This Page
Every entry goes to the country’s own register. OneShack does not copy anybody’s licence data onto this site: a register’s own page is always more current than a copy, and most of them say nothing about reuse. For a callsign anywhere in the world, our Callsign Lookup will tell you the country, the zones and the local time from the prefix alone.

Why the List Is Short
A country is on this page only when its register was opened and read on 25 September 2026 and found to be public. Several national regulators either publish no amateur register at all, or their sites could not be read from here — Germany’s Bundesnetzagentur refused the request outright. Rather than list a dozen links nobody has checked, this page carries the ones that were. Tell us about a register we have missed and we will check it and add it.
