Quick facts

About the 01249 dialling code

01249 is the UK geographic dialling code for Chippenham, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Chippenham area.

A full Chippenham number is normally written as 01249 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 01249 number no longer guarantees the caller is physically in Chippenham. Fraudsters also "spoof" local codes like 01249 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.

Calling 01249 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 1249 (the area code without its leading zero) and the local number.

History of the 01249 code

The code was 0249 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01249.

In the letter-dialling era the code had the mnemonic CH9 — on an old rotary dial, the letters CH (from Chippenham) sat on the same holes as the digits 249, so subscribers literally dialled the start of the town's name.

Is a call from 01249 safe?

Most 01249 calls are ordinary local calls from Chippenham homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01249 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 01249 (Chippenham) number from outside the UK, drop the leading zero and dial +44 1249 followed by the local number.
