What is the 0800 prefix?
Numbers beginning 0800 are UK freephone numbers — free to call from UK landlines and mobiles, paid for by the organisation that owns the number. Banks, utilities and government bodies use them heavily for outbound contact, which also makes them a favourite disguise for spoofed scam calls.
Every 0800 number sits inside a numbered block that Ofcom has allocated to a specific communications provider. The provider may run the numbers itself or sub-allocate them to resellers, which is why one prefix can be used by many unrelated organisations — and why the same prefix can produce both genuine calls and nuisance campaigns in the same week.

Frequently asked questions
Who called me from a 0800 number?
A 0800 number is a UK freephone prefix. The prefix alone can't identify the caller — look up the full 11-digit number on this site to see its Ofcom allocation and what other UK users have reported about it.
Are 0800 numbers safe to answer?
Most calls from any UK prefix are legitimate, but 0800 appears frequently in 'who called me' searches, which usually indicates heavy telemarketing or scam use of the range. Answer if you wish, but never share security details, one-time passcodes or payment information with an unexpected caller, and don't call back numbers you don't recognise.
How do I block calls from 0800 numbers?
Phones block individual numbers rather than whole prefixes: open your recent calls, tap the number and choose 'Block this caller'. For heavier protection, enable your network's call-screening service (free on BT, Sky, TalkTalk, Virgin Media and the mobile networks) and register with the Telephone Preference Service to cut legitimate marketing calls.
Why do I keep getting calls from different 0800 numbers?
Call centres and scam operations rotate through large pools of numbers in the same range, so blocking one 0800 number rarely stops the campaign. The pattern of many similar-looking numbers calling in sequence is itself a strong signal of an automated dialling operation rather than a genuine caller.
