Quick facts

About the 01654 dialling code

01654 is the UK geographic dialling code for Machynlleth, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Machynlleth area.

A full Machynlleth number is normally written as 01654 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 01654 number no longer guarantees the caller is physically in Machynlleth. Fraudsters also "spoof" local codes like 01654 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 01654 safe?

Most 01654 calls are ordinary local calls from Machynlleth homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01654 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 01654 (Machynlleth) number from outside the UK, drop the leading zero and dial +44 1654 followed by the local number.
