What are 07543 numbers?

Numbers starting 07543 are UK mobile numbers under Ofcom’s 07 mobile numbers range. Charged at your standard mobile rate and included in inclusive minutes.

Is 07543 an area code?

No — 07543 is not an area code. Area codes (or dialling codes), such as 0161 for Manchester or 0113 for Leeds, start 01 or 02 and tie a landline to a place. 07543 starts 07, so it is a UK mobile number range, not a geographic area. A call or text from an 07543 number therefore isn’t from a particular town — it’s from a mobile whose range Ofcom allocated to one of the networks in the table below (and the number may since have been ported to another network).

Which network do 07543 numbers belong to?

Ofcom’s weekly data shows which network each 07543 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 07543 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?
