Just What Are 01 Numbers And 02 Numbers?

01 numbers and 02 numbers are United kingdom telephone numbers that correspond with a particular place. They're also recognized as local area numbers, STD codes, and geographic numbers and each relates to a specific town, city or area inside the uk. One example is 01722 that relates to the city of Salisbury in the South of England and 0131 which relates to the Scottish city of Edingburgh.02 numbers are very much the same and were brought in in the year 2000. There are now about six hundred and fifty geographic area codes in operation.

It most likely comes as no surprise that the greatest population covered by a geographic number is London (020), although the largest area covered by them is Northern Ireland (028). Countries outside the UK using the same system are Jersey, Guernsey and the Isle of Man. A few 01 numbers are saved for the requirements of Television drama and they're purely fictitious to avoid a substantial volume of unwanted calls.

01 and 02 numbers are allocated to people when they set up a fixed landline. The area code will be fixed by where in the United kingdom the landline is, and the number following that will be unique to the landline.

Sometimes, geographic numbers are virtual. This means that someone in Salisbury (01722) can decide to buy a phone number relating to Edinburgh (0131) and have any telephone calls to the Edinburgh number immediately re-routed to a phone number of their choice, whether that be their Salisbury landline or a mobile. Because of this a company can seem to be local to one place when in reality it may not have any kind of physical presence there at all. This is useful to organizations when marketing themselves locally since the vast majority of people would rather deal with a local company and to phone a local telephone number.

Geographic numbers have undergone a few changes in recent times because of the rising population and increased use of technology. Telephone calls used to go through the Operator at a telephone exchange, but Subscriber Trunk Dialling (STD) was introduced in 1958 to cut out the necessity for an operator to physically put a call through. Unique codes for every single telephone exchange in the country were allotted in a process that took right until 1979 to finish.

PhONEday, took place in 1995, and came about to allow the number "1" to be inserted into all UK geographic area codes, enlarging the range of numbers available. This meant that all geographic numbers now began with 01.

With even more population increase and the rise in second phone lines, the high demand for telephone numbers became impossible to keep up with and a new numbering system had to be created, so in 2000, the "Big Number Change" came into force and 02x area codes could be utilized.

For an idea of how the geographic numbers have changed through the years, London launched as 01 in the 1960's right through to 1990, changed to 071 and 081 (for inner and outer London) from 1990-1995, evolved again to 0171 and 0181 from 1995-200, and it's now 020.
