This isn't an area code. The '44' is the international dialling code for the UK and the '7' denotes that it is a mobile (cell) phone number, so could be anywhere in the UK. It's probably a scam.

A London (UK) phone number has 8 digits. If you wish to dial a London (UK) phone number from outside the London area (or a mobile phone) you need to prefix the 8 digits by the 3 digit London area code of 020 (which would normally be displayed in brackets before the number viz: (020) yxxx xxxx - the y is either 3, 7 or 8). If you wish to dial it from outside the UK, you'll need the international prefix for your country, followed by the country code of 44 plus the London area code without the leading zero plus the 8 digits, ie: +44 20 yxxx xxxx

UK telephone area code 020 is London. A number beginning with 020 8401 could be located anywhere within the greater London 020 area, including both the former "inner London" and "outer London" zones. No more detailed geographic information is possible.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
