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 ...

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.
