Quick facts

About the 01843 dialling code

01843 is the UK geographic dialling code for Thanet, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Thanet area.

A full Thanet number is normally written as 01843 XXXXXX. You can dial the local part on its own from within the same area, or the full number from anywhere in the UK.

Because of UK number portability and internet calling, a 01843 number no longer guarantees the caller is physically in Thanet. Fraudsters also "spoof" local codes like 01843 so an unknown call looks like a nearby business or neighbour — so treat an unexpected call on what is actually said, not on the area code alone.

Is a call from 01843 safe?

Most 01843 calls are ordinary local calls from Thanet homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01843 prefix so you are more likely to answer. Never share bank details, passwords or one-time security codes with an unexpected caller, even when the number looks local — hang up and call the organisation back on a number you have verified yourself.

To call a 01843 (Thanet) number from outside the UK, drop the leading zero and dial +44 1843 followed by the local number.
