What are 0905 numbers?
Numbers starting 0905 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
616 number blocks under 0905, of which
612 are allocated to
57 providers.
Who uses 0905 numbers?
Competition lines, voting, adult services and technical-support lines. Legitimate uses exist, but 09 is also a classic scam callback trap.

…and 45 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 0905 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 0905 number back unless you know exactly what it is and costs.
