Many will be aware of my fastidious nature when it comes to phone numbers, but I've never shared with a wider audience. Maybe this doesn't provide a forum for a wider audience: be that as it may.
The 020 London prefix is now six years old, having been introduced on 22 April 2000. It superseded the 0171 and 0181 introduced in 1995, which in turn replaced 071 and 081 (1990), before which, it was simply 01. (I'll always remember Going Live being 01 811 8055.) BT's extensive publicity surrounding the 2000 change concentrated heavily on the 7 (inner London) and 8 (outer London) that succeeded the 020 prefix, which means that to this day, the vast majority of people believe there to be two London prefixes: 0207 and 0208. (My brother has recently been given a three, instead of the usual 7 and 8, but that's another aside.)
As you can imagine, this frustrates the hell out of me. People quote their number as 0207 XXX YYYY. The correct grouping is 020 7XXX YYYY. When I used to contact our local curry house in Clapham, I used to have to give my phone number. Here's the associated conversation (always with the same chap) that happened for every single order, verbatim:
Order taker: your phone number?
Me: 020
Order taker: 0207
Me: 7XXX
Order taker: XXX
Me: YYYY
Order taker: YYYY
Order taker: Your order please?
The behaviour has more recently sprung up in mobile phone numbers. It seems that the first five digits are too long to string together (even though they always start with 07), so people split it after three, or sometimes four. It seems somewhat random, more guided by the presence of double-digits as opposed to following a pre-defined breakdown.
So, please from now on could you quote your London numbers as 020, XXXX, YYYY. And your mobiles should be as follows: 07XXX, YYYYYY.
Many thanks.
