About the 01228 dialling code
01228 is the UK geographic dialling code for Carlisle, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Carlisle area.
A full Carlisle number is normally written as 01228 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 01228 number no longer guarantees the caller is physically in Carlisle. Fraudsters also "spoof" local codes like 01228 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 01228 code
The code was 0228 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01228.
In the letter-dialling era the code had the mnemonic CA8 — on an old rotary dial, the letters CA (from Carlisle) sat on the same holes as the digits 228, so subscribers literally dialled the start of the town's name.

Is a call from 01228 safe?
Most 01228 calls are ordinary local calls from Carlisle homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01228 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 01228 (Carlisle) number from outside the UK, drop the leading zero and dial +44 1228 followed by the local number.
