Quick facts

About the 01475 dialling code

01475 is the UK geographic dialling code for Greenock, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Greenock area.

A full Greenock number is normally written as 01475 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 01475 number no longer guarantees the caller is physically in Greenock. Fraudsters also "spoof" local codes like 01475 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 01475 from abroad

From outside the UK, dial your international access prefix, then the UK country code 44, then 1475 (the area code without its leading zero) and the local number.

History of the 01475 code

The code was 0475 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01475.

In the letter-dialling era the code had the mnemonic GR5 — on an old rotary dial, the letters GR (from Greenock) sat on the same holes as the digits 475, so subscribers literally dialled the start of the town's name.

Is a call from 01475 safe?

Most 01475 calls are ordinary local calls from Greenock homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01475 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 01475 (Greenock) number from outside the UK, drop the leading zero and dial +44 1475 followed by the local number.
