About the 01780 dialling code
01780 is the UK geographic dialling code for Stamford, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Stamford area.
A full Stamford number is normally written as 01780 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 01780 number no longer guarantees the caller is physically in Stamford. Fraudsters also "spoof" local codes like 01780 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 01780 code
The code was 0780 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01780.
In the letter-dialling era the code had the mnemonic ST0 — on an old rotary dial, the letters ST (from Stamford) sat on the same holes as the digits 780, so subscribers literally dialled the start of the town's name.

Is a call from 01780 safe?
Most 01780 calls are ordinary local calls from Stamford homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01780 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 01780 (Stamford) number from outside the UK, drop the leading zero and dial +44 1780 followed by the local number.
