About the 01665 dialling code
01665 is the UK geographic dialling code for Alnwick, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Alnwick area.
A full Alnwick number is normally written as 01665 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 01665 number no longer guarantees the caller is physically in Alnwick. Fraudsters also "spoof" local codes like 01665 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 01665 safe?
Most 01665 calls are ordinary local calls from Alnwick homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01665 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 01665 (Alnwick) number from outside the UK, drop the leading zero and dial +44 1665 followed by the local number.
