What are 01638 6XXXXX numbers?

Any UK number matching 01638 6XXXXX sits in the 01638 dialling code for Newmarket. Ofcom hands these numbers to communications providers in blocks; this range contains 28 blocks, of which 14 are allocated and usable. Calls from these numbers are typically homes and businesses in the Newmarket area — or organisations elsewhere that keep a local 01638 presence using VoIP.

Who holds 01638 6… 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 28 blocks Ofcom lists, 14 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 01638 6… number safe?

A local-looking number is never proof of who is calling: fraudsters spoof 01638 caller IDs so their calls look like they come from Newmarket (‘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.
