Where is area code 7045 in England?

All UK numbers starting "70" (or "070" when dialling within the UK) are Personal Numbers.

These are special numbers which people or companies can use to manage their calls across several phones. For example, the owner of a Personal Number might set it to ring their home phone in the evening, and their mobile phone in the daytime.

They are also sometimes used by people who do not want to reveal their real home or mobile phone number.
