…and 31 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

Treat unexpected 0900 contact with real caution. The classic scam is baiting you into ringing a premium number back (missed calls, fake prize texts) and keeping you on the line. Never call an 0900 number back unless you know exactly what it is and costs.
