What are 0900 numbers?
Numbers starting 0900 are UK premium rate
numbers in Ofcom’s 09 premium-rate numbers
range. They are not tied to any town or city. Ofcom currently lists
566 number blocks under 0900, of which
557 are allocated to
45 providers.
Who uses 0900 numbers?
Competition lines, voting, adult services and technical-support lines. Legitimate uses exist, but 09 is also a classic scam callback trap.

…and 33 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.
