What are 01788 4XXXXX numbers?
Any UK number matching 01788 4XXXXX sits in the
01788 dialling code for Rugby.
Ofcom hands these numbers to communications providers in blocks; this range
contains 64 blocks, of which
47 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Rugby area — or
organisations elsewhere that keep a local 01788 presence using
VoIP.

…and 34 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 64 blocks Ofcom lists, 17 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 01788 4… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01788 caller IDs so their calls look like they come from Rugby (‘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.
