What are 01535 6XXXXX numbers?
Any UK number matching 01535 6XXXXX sits in the
01535 dialling code for Keighley.
Ofcom hands these numbers to communications providers in blocks; this range
contains 10 blocks, of which
10 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Keighley area — or
organisations elsewhere that keep a local 01535 presence using
VoIP.
Who holds 01535 6… number ranges?
| Range holder (allocated by Ofcom) | Number blocks | Example range |
|---|---|---|
| BT | 8 | 01535 60XXXX |
| Virgin Media Limited | 1 | 01535 67XXXX |
| Vodafone Ltd (C&W) | 1 | 01535 62XXXX |
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.
Is a call from a 01535 6… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01535 caller IDs so their calls look like they come from Keighley (‘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.
