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. | 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. |

| 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: | The spreadsheet released in June 2026 included the missing "Z" callsigns although it's known a valid licence callsign M7FMI is still missing.
