About the 01700 dialling code
01700 is the UK geographic dialling code for Rothesay, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Rothesay area.
A full Rothesay number is normally written as 01700 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 01700 number no longer guarantees the caller is physically in Rothesay. Fraudsters also "spoof" local codes like 01700 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 01700 safe?
Most 01700 calls are ordinary local calls from Rothesay homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01700 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 01700 (Rothesay) number from outside the UK, drop the leading zero and dial +44 1700 followed by the local number.
