Ofcom’s weekly data shows which network each 07821 range was originally allocated to — the table above. Bear in mind UK mobile numbers are very frequently ported, so the person calling you may be on a different network today; the allocation is a starting point, not proof.
Had a call or text from an 07821 number?
Unexpected calls and texts from unfamiliar mobile numbers are a common scam pattern — missed-call (‘Wangiri’) baiting, fake delivery texts and bank-impersonation calls all use them. Don’t ring back numbers you don’t recognise without checking first. Our plain-English guide covers what to do: Who called me from a +44 7 mobile number?
