Quick facts

About the 01859 dialling code

01859 is the UK geographic dialling code for Harris, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Harris area.

A full Harris number is normally written as 01859 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 01859 number no longer guarantees the caller is physically in Harris. Fraudsters also "spoof" local codes like 01859 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 01859 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 1859 (the area code without its leading zero) and the local number.

History of the 01859 code

The code was 0859 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01859.

Is a call from 01859 safe?

Most 01859 calls are ordinary local calls from Harris homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01859 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 01859 (Harris) number from outside the UK, drop the leading zero and dial +44 1859 followed by the local number.
