What are 028 1XXX XXXX numbers?

Any UK number matching 028 1XXX XXXX sits in the 028 dialling code for Northern Ireland. Ofcom hands these numbers to communications providers in blocks; this range contains 1,000 blocks, of which 5 are allocated and usable. Calls from these numbers are typically homes and businesses in the Northern Ireland area — or organisations elsewhere that keep a local 028 presence using VoIP.

Who holds 028 1… number ranges?

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 1,000 blocks Ofcom lists, 995 are protected (reserved by Ofcom and not in use). A call appearing to come from an unallocated block is a strong sign of a spoofed number.

Is a call from a 028 1… number safe?

A local-looking number is never proof of who is calling: fraudsters spoof 028 caller IDs so their calls look like they come from Northern Ireland (‘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.
