Call signs in the United Kingdom
Call signs in United Kingdom include a three letter country code, and a series of letters and numbers.[1][2][3]
Call signs are regulated internationally by the ITU as well as nationally in the UK by the Office of Communications (Ofcom).[4] It regulates amateur radio in the country as an independent regulator and competition authority for the UK communications industries, with responsibilities across television, radio, telecommunications and wireless communications services. It assigns call signs, issues amateur radio licences, allots frequency spectrum, and monitors the radio waves. Ofcom is no longer responsible for setting and conducting amateur radio exams, which are now run by the Radio Society of Great Britain on their behalf.[5]
The Radio Society of Great Britain[6] (RSGB) is the United Kingdom's recognised national society for amateur radio operators. The society's patron is Prince Philip, Duke of Edinburgh, and it represents the interests of the UK’s licensed radio amateurs.
Call sign blocks for telecommunication
The International Telecommunication Union has assigned Great Britain the following call sign blocks for all radio communication, broadcasting or transmission:[7]
| Call sign block | Principal use |
|---|---|
| GAA–GZZ | domestic |
| MAA–MZZ | domestic |
| VPA–VQZ | Oceanic islands, Antarctica |
| VSA–VSZ | |
| ZBA–ZJZ | Gibraltar, Middle East, south Atlantic |
| ZNA–ZOZ | |
| ZQA–ZQZ | |
| 2AA–2ZZ | domestic |
While not directly related to call signs, the International Telecommunication Union (ITU) further has divided all countries assigned amateur radio prefixes into three regions; Great Britain is located in ITU Region 1.

Special event call signs
Ofcom reserves the right to issue temporary special event call signs to licensed amateurs holding a full licence.[11]
Special event call signs are issued with a 'GB' prefix, but others like GQ, GO, MQ, GA, MO and 2O have been issued in special cases. Ofcom also allows numerals in special event call sign suffixes. For instance GB75RD was a special event sign for the 75th anniversary of the Reading and District Amateur radio club.[12] More recently Ofcom have agreed to what was a very special arrangement for the use of the Special Event Station call sign Gx100RSGB during 2013 to mark the 100th anniversary of the RSGB (where "x" is replaced by the secondary location identifier, M, W, I, D, U and J, etc. but never with B to form the typical 'GB' prefix for other special events.)
Exceptionally, call signs taking the form 'GB3xx' are usually allocated to repeaters whilst beacons usually take the 'GB3xxx' form.
Reciprocal agreements
Holders of licences in countries signed up to CEPT TR 61-01[13] operate with their home call sign prefixed with an M/ plus the additional country identifier when necessary (e.g. MM,MI, MW etc.). Holders of licences in countries signed up to CEPT TR 61-02[14] can operate for 3 months before needing a Great Britain call sign as issued by Ofcom.
