Ofcom don't advertise when any other area gets a new range of local
numbers, why
should they for London ? Numbers of the format (020) 7xxx xxxx and (020) 8xxx
xxxx are not affected by the introduction of (020) 3xxx xxxx unlike the earlier
changes which affected the area code and / or existing local numbers.

Except I did spot a 'news' item in the Metro (Local Free paper to London
and other cities) a few months ago along the lines that 'London is to
get a new dialling code - 0203'.

It's no wonder people think the way they do when this sort of rubbish is
published.
