The code 0999 was used for dialling by PO operators only to mobile relief exchanges in the Glasgow area in the 1970s. Likely reason for non-allocation of 01999 is similarity to the 999 emergency services access code.
This is the format used by most areas. It has a four-digit area code (after the initial zero) and a six digit subscriber number, and is known as 4+6 format. These area codes were changed by adding a "1" directly after the initial zero as a part of PhONEday in 1995. Just short of 581 areas use this format, and the area codes range from 01200 to ...
Each city with a director system was assigned a three-digit code, in which the second digit corresponded to the first letter of the city name on the telephone dial, except London which had the two-digit code 01.

Of the 16 area codes freed up for alternative use in the 1980s, at least 11 were re-used for other services. For example, the 0401 area code was re-allocated to Cellnet mobile services. Five of the area codes remained unused, including 01632, which is now partially reserved for fictitious telephone numbers. In 1995, the PhONEday changes for ...

PhONEday followed a change made in May 1990, when the old London area code 01 was released from use, permitting all United Kingdom geographic numbers to begin with this prefix. Originally planned in 1991 to take place in 1994, [ 2 ] in 1992 the change was postponed until the Easter Sunday bank holiday in 1995.

Some widespread misunderstandings about area codes came about with the Big Number Change, most notably with London area codes. 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.
