What are 01273 1XXXXX numbers?
Any UK number matching 01273 1XXXXX sits in the
01273 dialling code for Brighton.
Ofcom hands these numbers to communications providers in blocks; this range
contains 100 blocks, of which
22 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Brighton area — or
organisations elsewhere that keep a local 01273 presence using
VoIP.

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 100 blocks Ofcom lists, 77 are protected (reserved by Ofcom and not in use) and 1 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 01273 1… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01273 caller IDs so their calls look like they come from Brighton (‘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.
