About the 01636 dialling code
01636 is the UK geographic dialling code for Newark-on-Trent, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Newark-on-Trent area.
A full Newark-on-Trent number is normally written as 01636 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 01636 number no longer guarantees the caller is physically in Newark-on-Trent. Fraudsters also "spoof" local codes like 01636 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 01636 code
The code was 0636 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01636.
In the letter-dialling era the code had the mnemonic NE6 — on an old rotary dial, the letters NE (from Newark-on-Trent) sat on the same holes as the digits 636, so subscribers literally dialled the start of the town's name.

Is a call from 01636 safe?
Most 01636 calls are ordinary local calls from Newark-on-Trent homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01636 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 01636 (Newark-on-Trent) number from outside the UK, drop the leading zero and dial +44 1636 followed by the local number.
