What are 01737 7XXXXX numbers?
Any UK number matching 01737 7XXXXX sits in the
01737 dialling code for Redhill.
Ofcom hands these numbers to communications providers in blocks; this range
contains 46 blocks, of which
18 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Redhill area — or
organisations elsewhere that keep a local 01737 presence using
VoIP.
Who holds 01737 7… number ranges?
| Range holder (allocated by Ofcom) | Number blocks | Example range |
|---|---|---|
| GCI Network Solutions Limited | 6 | 01737 742XXX |
| BT | 5 | 01737 75XXXX |
| Lumen Technologies UK Limited | 5 | 01737 720XXX |
| DRD Communications Limited | 1 | 01737 701XXX |
| Vodafone Ltd (C&W) | 1 | 01737 73XXXX |
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 46 blocks Ofcom lists, 28 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 01737 7… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01737 caller IDs so their calls look like they come from Redhill (‘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.
