…and 181 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.

Scam & cost warnings

Always note the cost before calling an 0845 number back: you pay a service charge plus your provider’s access charge, which can make even short calls expensive. A missed call from an 0845 number you don’t recognise is rarely worth returning.
