About the 01559 dialling code
01559 is the UK geographic dialling code for Llandysul, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Llandysul area.
A full Llandysul number is normally written as 01559 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 01559 number no longer guarantees the caller is physically in Llandysul. Fraudsters also "spoof" local codes like 01559 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 01559 code
The code was 0559 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01559.
In the letter-dialling era the code had the mnemonic LL9 — on an old rotary dial, the letters LL (from Llandysul) sat on the same holes as the digits 559, so subscribers literally dialled the start of the town's name.

Is a call from 01559 safe?
Most 01559 calls are ordinary local calls from Llandysul homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01559 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 01559 (Llandysul) number from outside the UK, drop the leading zero and dial +44 1559 followed by the local number.
