Quick facts

About the 01865 dialling code

01865 is the UK geographic dialling code for Oxford, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Oxford area.

A full Oxford number is normally written as 01865 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 01865 number no longer guarantees the caller is physically in Oxford. Fraudsters also "spoof" local codes like 01865 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 01865 safe?

Most 01865 calls are ordinary local calls from Oxford homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01865 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 01865 (Oxford) number from outside the UK, drop the leading zero and dial +44 1865 followed by the local number.
