What are 07003 numbers?
Numbers starting 07003 are UK personal numbering (070)
numbers under Ofcom’s
070 personal numbers range.
070 numbers are 'follow-me' personal numbers, NOT mobiles, and can be expensive to call - a common nuisance-call disguise.

070 personal numbers look like mobiles but are not: they are ‘follow-me’ redirection services that can cost far more to call and are a well-known nuisance- and scam-call disguise. Treat unexpected calls from 07003 numbers with real caution and check the cost before ringing back.
Had a call or text from an 07003 number?
Unexpected calls and texts from unfamiliar personal 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 an 070 number?
