What are 01790 7XXXXX numbers?
Any UK number matching 01790 7XXXXX sits in the
01790 dialling code for Spilsby.
Ofcom hands these numbers to communications providers in blocks; this range
contains 46 blocks, of which
13 are allocated and usable. Calls from these
numbers are typically homes and businesses in the Spilsby area — or
organisations elsewhere that keep a local 01790 presence using
VoIP.
Who holds 01790 7… number ranges?
| Range holder (allocated by Ofcom) | Number blocks | Example range |
|---|---|---|
| Gamma Telecom Holdings Limited | 7 | 01790 720XXX |
| BT | 2 | 01790 75XXXX |
| Magrathea Telecommunications Limited | 1 | 01790 78XXXX |
| Net-Work Internet Ltd | 1 | 01790 79XXXX |

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 46 blocks Ofcom lists, 33 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 01790 7… number safe?
A local-looking number is never proof of who is calling: fraudsters spoof 01790 caller IDs so their calls look like they come from Spilsby (‘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.
