Just to clarify Ian's point: most areas have additional codes which
can be used to connect with local areas; that is, non-STD (Standard
Truck Dialling) codes. While STD codes all begin with 0, these
additional codes begin with non-zero. For example, to call from Newark
to Nottingham, a distance of about 30 miles centre-to-centre, you can
optionally use the code 91 instead of the STD code of 0602.  The STD
code will of course always work.

I assume that these non-STD codes are anachronistic, and will
gradually disappear. I'm not sure what effect they have on charging.

I work for BT but have no involvement with the operation or management
of the UK or International networks, and do not speak for them on this
subject.
