PhONEday had cleared area codes from 02 to 09 of all geographic allocations by converting 9-digit numbers to 10-digit 01 numbers (and, in parts of at least 47 area codes, 8-digit numbers to 9-digit 01 numbers). After PhONEday, all pre-existing 9-digit mobile, non-geographic, premium rate, personal and pager numbers from 02 to 09 remained in place.

There is a widespread but erroneous assumption that London has several area codes – 0203, 0204, 0207 and 0208 – whereas, in fact, it has just one: 020. Similar misunderstandings came about with a few other area codes.
