Telephone number

Owing to the marked increase in demand for telephone numbers to be available for allocation since the 1990s, the United Kingdom's telephone numbering system has been restructured several times on both a national and regional level, resulting in several modifications to the way British telephone numbers are written.

Mobile phone

A standard United Kingdom fixed telephone number (i.e. a landline, or geographical number, as opposed to a mobile telephone number or special rate non-geographic fixed line) is divided into three parts, the trunk prefix code (0 in the UK), an STD code (area code) followed by a local number.

Caller ID

For readability, and to distinguish geographic location, telephone numbers are often spoken, displayed and published with a gap between the area code and local number, or with the area code in (parentheses).

London Transport (brand)

London TransportLTLondon Transport roundel
In the early 1960s London telephones still had exchange names, the first three letters having to be dialled before the four-digit local number, e.g. ABBey 1234 (London Transport).

Easter

To free up more numbers for future use, on Easter Sunday, 16 April 1995 (dubbed "PhONEday"), an extra digit "1" was inserted after the initial zero into all except five geographical area codes nationwide, so inner and outer London became 0171 and 0181 respectively — for example (0171) 222 1234.

Numerous examples of incorrectly formatted telephone numbers may still be seen in and around London, including signwriting on shop-fronts and commercial vehicles, and in newspaper advertisements.

Telefónica Europe

A 2005 television advertisement for the mobile telephony provider O2 promoted a service that allows a user to select two area codes they can call for a reduced price; it also incorrectly showed 0207 and 0208 as different "area codes".
