About the 01423 dialling code

01423 is the UK geographic dialling code for Harrogate, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Harrogate area.

A full Harrogate number is normally written as 01423 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 01423 number no longer guarantees the caller is physically in Harrogate. Fraudsters also "spoof" local codes like 01423 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.

History of the 01423 code

The code was 0423 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01423.

In the letter-dialling era the code had the mnemonic HA3 — on an old rotary dial, the letters HA (from Harrogate) sat on the same holes as the digits 423, so subscribers literally dialled the start of the town's name.

Is a call from 01423 safe?

Most 01423 calls are ordinary local calls from Harrogate homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01423 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 01423 (Harrogate) number from outside the UK, drop the leading zero and dial +44 1423 followed by the local number.
