What are 01740 6XXXXX numbers?
Any UK number matching 01740 6XXXXX sits in the
01740 dialling code for Sedgefield.
Ofcom hands these numbers to communications providers in blocks; this range
contains 37 blocks, of which
20 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Sedgefield area — or
organisations elsewhere that keep a local 01740 presence using
VoIP.
Who holds 01740 6… number ranges?
| Range holder (allocated by Ofcom) | Number blocks | Example range |
|---|---|---|
| Virgin Media Limited | 8 | 01740 600XXX |
| BT | 5 | 01740 62XXXX |
| Gamma Telecom Holdings Limited | 5 | 01740 615XXX |

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, 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 01740 6… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01740 caller IDs so their calls look like they come from Sedgefield (‘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.
