What are 01858 9XXXXX numbers?
Any UK number matching 01858 9XXXXX sits in the
01858 dialling code for Market.
Ofcom hands these numbers to communications providers in blocks; this range
contains 91 blocks, of which
8 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Market area — or
organisations elsewhere that keep a local 01858 presence using
VoIP.

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 91 blocks Ofcom lists, 83 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 01858 9… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01858 caller IDs so their calls look like they come from Market (‘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.
