What are 0151 4XX XXXX numbers?
Any UK number matching 0151 4XX XXXX sits in the
0151 dialling code for Liverpool.
Ofcom hands these numbers to communications providers in blocks; this range
contains 100 blocks, of which
67 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Liverpool area — or
organisations elsewhere that keep a local 0151 presence using
VoIP.
0151 496 0000 falls in this range and is reserved by Ofcom for TV and radio dramas — it can never connect to a real subscriber, which is why we use it as the live example above.

…and 14 more providers hold smaller allocations in this range.
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 100 blocks Ofcom lists, 28 are protected (reserved by Ofcom and not in use) and 5 are free/unallocated. A call appearing to come from an unallocated block is a strong sign of a spoofed number.
Is a call from a 0151 4… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 0151 caller IDs so their calls look like they come from Liverpool (‘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.
