London Area Codes
Attention London: Your phone numbers are prefixed (020).
Not (0208) or (0207), just (020).
I know it’s tough moving from 0181 and 0171, but those two codes were merged back into one area code (020) in April 2000. You simply prefix a 7 or 8 to the rest of your number depending on which code you were in before.
(0181) ### #### becomes (020) 8### ####
(0171) ### #### becomes (020) 7### ####
You may not think this is important, but it is. If you think about how area codes actually work, you’ll realise why.
It’s been 7 years now. It’s time you figured it out.
