What are 0870 numbers?
Numbers starting 0870 are UK service number
numbers in Ofcom’s 084 & 087 service numbers
range. They are not tied to any town or city. Ofcom currently lists
846 number blocks under 0870, of which
841 are allocated to
154 providers.
Who uses 0870 numbers?
Support and booking lines; like 084, increasingly replaced by 03 numbers because of the cost to callers.

…and 142 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 0870 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 0870 number you don’t recognise is rarely worth returning.
