About the 01738 dialling code
01738 is the UK geographic dialling code for Perth, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Perth area.
A full Perth number is normally written as 01738 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 01738 number no longer guarantees the caller is physically in Perth. Fraudsters also "spoof" local codes like 01738 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 01738 safe?
Most 01738 calls are ordinary local calls from Perth homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01738 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 01738 (Perth) number from outside the UK, drop the leading zero and dial +44 1738 followed by the local number.
