The 020 4 numbers are for the entire London area, as are the 020 3 / 7 / 8. The demarcation of ‘inner’ and ‘outer’ London was abolished in the year 2000.
There is no change to any existing London telephone numbers.
Ofcom has requested that we strengthen our customers understanding that the area code for London is 020, which is followed by an 8 digit subscriber number.
By using IP telephony services, or NTS virtual numbers, it is of course, possible to have a virtual London presence without the cost of a London based office.
