 In 2000 Short Contest Callsigns with MZ and GZ prefixes were introduced for use in the Shetland Islands, {{ :2000-12_radcom_new_z_rsl.jpg?linkonly | RSGB December 2000 RadCom announcement}}
-In 2008 Ofcom said they did not regard the RSL as being part of the core UK callsign and in 2013 stated the words in the licence actually meant the Main Station RSL should be used when visiting other regions but they were happy for amateurs to continue with existing practice of changing RSL if they wished.  RSGB published this explanation by Ofcom on their website [[https://web.archive.org/web/20150928061916/http://rsgb.org/main/archive/consultation-archive/ofcom-consultations/licence-review-preparation/regional-secondary-locator/|External Link]]

 In 2014 Ofcom proposed making it clear in the licence that the RSL was optional, this generated opposition from the RSGB so Ofcom decided not to add clarity to the licence at that time but Ofcom continued to consider that amateurs with M or G callsigns could either omit the RSL or give the RSL for the region they were visiting if they wished.

 The spreadsheet shows Individual, Club and Temporary Reciprocal licence call signs that are either Allocated or Reserved along with a few call signs marked as Available but any call sign that **does not** appear in the spreadsheet (or in Forbidden) is also Available.
-None of the callsigns are shown with an RSL so 2E0ABC would appear as 20ABC but Ofcom has been transitioning "2" prefix callsigns to M8 or M9 prefixes and Ofcom will no longer issue any "2" prefix callsign.  When viewed in Excel a few spreadsheet rows may display a **date** instead of the call sign, the result of a formatting issue, 20JAN appears as 20-Jan, 21DEC as 21-Dec.

-Note the Foundation M3 call series shows thousands of callsigns with Reserved status despite having been in that state for well over the required 5 years.   They are in fact Available for issue but those who've passed their Foundation exam will need to ring Ofcom, or use Ofcom's Online Chat facility, to ask them to change the status to Available which Ofcom can do almost instantly for you.

 The spreadsheet released in June 2026 included the missing "Z" callsigns although it's known a valid licence callsign M7FMI is still missing. This was believed to be because Ofcom had used an incorrect record Type field of blank instead of "Call sign - Amateur" in the main licence database as a result M7FMI isn't extracted to the spreadsheet.   This spreadsheet shows almost 106,000 Allocated call signs for Individual, Club and Temporary Reciprocal licences:
