What are 0843 numbers?
Numbers starting 0843 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
616 number blocks under 0843, of which
601 are allocated to
132 providers.
Who uses 0843 numbers?
Customer service and booking lines; their cost to callers has made many organisations move to 03 numbers instead.

…and 120 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 0843 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 0843 number you don’t recognise is rarely worth returning.
