About 07381 numbers in the UK

The 07381 prefix is part of the UK National Telephone Numbering Plan administered by Ofcom and falls into the Mobile family. 07381 is a UK mobile range. In the latest Ofcom data the 07381 blocks are allocated to Telefonica UK Limited. Calls and texts to 07381 numbers are charged at your standard mobile rate.

Ofcom allocates 07381 number ranges to UK communications providers (Range Holders) in 1,000- or 10,000-number blocks.

Who owns a 07381 number?

07381 is not an area code — UK mobiles have no geography. It is a five-digit slice of the national 07 mobile range that Ofcom hands to a mobile network operator in blocks, which the operator then assigns to individual customers. In our latest Ofcom snapshot the largest holder of 07381 blocks is Telefonica UK Limited, but a number can be ported to a different network while keeping its digits, so the range holder is the original allocatee rather than necessarily today’s provider.

That means the honest answer to “who owns this 07381 number” has two layers. The network behind the block is public Ofcom data — shown in the table below and on every per-number result page. The person behind the specific number is not: UK rules keep mobile subscribers out of any public directory, and no legitimate free service can reveal a stranger’s name from their mobile number alone. Anyone promising that is best avoided.

What you can do for free: paste the full 07381 number into the lookup above to confirm the range holder and run a live AI internet check that surfaces public scam reports and forum mentions of that exact number. For the wider picture see who called me? and UK mobile networks by prefix.

Spotting a fake 07381 call

• Check the Range Holder column below: a 07381 number that doesn’t map cleanly to one of the UK-licensed providers listed is the first amber flag. Genuine UK callers on this prefix come through one of the carriers Ofcom has actually allocated the block to.
• Watch the script. Legitimate 07381 callers — whether banks, delivery firms, public-sector services or commercial brands — don’t pressure you into reading codes from a text, keying in passwords, or installing remote-access software while still on the line.
• If you weren’t expecting a 07381 call, hang up and ring back via a number printed on the organisation’s website or a recent letter, not the CLI that just rang you. Most 07381 scams collapse the moment you switch to a verified channel.
• Paste the exact digits into the lookup form above for a live AI internet check. If the number has been mass-reported on consumer forums, that surfaces in the per-number result alongside the structured Ofcom Range Holder data.
