Find a UK dialling code

Returns UK postal areas and dialling codes for a UK location, and vice versa.

Dialling codes can be found by entering a location name or postal area such as YO or YO10 5NP. Alternatively you can enter a dialling code to find out where that number is calling from. Dialling codes correspond to a specific geographical area. Integrating this service will help you to identify where a call is coming from or determine if you have the correct telephone number for a specific area.
