…and 38 more providers hold smaller allocations in this range.

Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.

Not every block in this range is in service: of the 154 blocks Ofcom lists, 84 are protected (reserved by Ofcom and not in use) and 3 are free/unallocated. A call appearing to come from an unallocated block is a strong sign of a spoofed number.

Is a call from a 01387 3… number safe?

A local-looking number is never proof of who is calling: fraudsters spoof 01387 caller IDs so their calls look like they come from Dumfries (‘neighbour spoofing’). If an unexpected caller asks for personal, banking or one-time-code details, hang up and ring the organisation back on a number you find independently. To put a name to a caller, see who called me?; to report one, see how to report a scam number.
