Who owns this number range?

Ofcom issues UK phone numbers to licensed telecoms companies in blocks, usually of 1,000 or 10,000 numbers. Whoever is issued a block is its range holder. They might use the numbers themselves, give them to their own customers, or rent them out to resellers and internet phone companies.

Probably not directly. The call is more likely from one of its customers, from a reseller using its numbers, or from someone faking the caller ID. Look up the exact number and read its reports.

The blocks are taken from the numbering allocation files Ofcom publishes (most recent allocation: 26 October 2026). Reports on each company's page come from Who Called Me Check visitors and are not checked for accuracy.
