Ah, so new suscribers in an area potentially get a brand new district
number that's unrelated to that of all the other subscribers in that
area? Yes, I suppose that's one way of solving the problem. Do all
subscribers in one area get one new code and all those in another
area get different code: can you still say "xxxx [a new code] is
Harrow, alongside yyyy [the existing code]" or is the
code-to-location mapping lost?
The code to location mapping is, I believe, becoming blurred. My BT phone
is 020 8863 xxxx, and my NTL phone line 020 8357 xxxx.
This is indeed the case. I used to work in Intelligent Networks,
setting up number translation services for large national companies
who would want all callers to be routed to their nearest local office.
Firstly, they would invariably give us their requirements in terms of
postcodes, which would necessitate a long explanation to the account
manager of how postcodes were a system used by the Royal Mail to
distribute letters and parcels, and there wasn't a one-to-one mapping
to STD codes, and secondly, it was usually impossible to meet their
requirements when it came to non-BT numbers, as cable companies seemed
to assign their Manchester (for example) 1000-number blocks to cover
the entire city, in the order customers were signed up...
