What are 01403 7XXXXX numbers?

Any UK number matching 01403 7XXXXX sits in the 01403 dialling code for Horsham. Ofcom hands these numbers to communications providers in blocks; this range contains 37 blocks, of which 11 are allocated and usable. Calls from these numbers are typically homes and businesses in the Horsham area — or organisations elsewhere that keep a local 01403 presence using VoIP.

Who holds 01403 7… 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 37 blocks Ofcom lists, 26 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 01403 7… number safe?

A local-looking number is never proof of who is calling: fraudsters spoof 01403 caller IDs so their calls look like they come from Horsham (‘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.
