how many digits do uk phone numbers have
Telephone numbers in the United Kingdom Since 28 April 2001, almost all geographic numbers and most non-geographic numbers have 9 or 10 national (significant) numbers after the "0" trunk code. All mobile telephone numbers have 10 national (significant) numbers after the "0" trunk code. The overall structure of the UK's National Numbering Plan is:[1]
Telephone number The number contains the information necessary to identify uniquely the intended endpoint for the telephone call. Each such endpoint must have a unique number within the public switched telephone network. Most countries use fixed length numbers (for normal lines at least) and therefore the number of endpoints determines the necessary length of the telephone number. It is also possible for each subscriber to have a set of shorter numbers for the endpoints most often used. These "shorthand" or "speed calling" numbers are automatically translated to unique telephone numbers before the call can be connected. Some special services have their own short numbers (e.g., 1-1-9, 9-1-1,1-0-0, 1-0-1, 1-0-2, 0-0-0, 9-9-9, 1-1-1, and 1-1-2 being the Emergency Services numbers for China, Japan, India, South Korea, Taiwan and Sri Lanka; Canada and the United States; Israel (Police); Israel (Paramedic); Israel (Fire); Australia; the United Kingdom, Ireland, South Africa, Poland, Saudi Arabia, the United Arab Emirates, Morocco, Macao, Bahrain, Qatar, Bangladesh, Botswana, Ghana, Kenya, Hong Kong, Malaysia, Mauritius, Singapore, Zimbabwe, Trinidad, Tobago, New Zealand, Kuwait, the European Union and the Philippines respectively.)
National Insurance number Persons from abroad who wish to work in the UK, or those to whom a number was not initially allocated as children, must apply for a number through the Department for Work and Pensions (DWP).[6] The prefixes used are typically different from those used in the normal run.[6][not in citation given]
Social Security number The last four digits are serial numbers. They represent a straight numerical sequence of digits from 0001 to 9999 within the group.
999 (emergency telephone number) Countries and territories using 999 include Bahrain, Bangladesh, Botswana, Ghana, Hong Kong, Kenya, Macau, Malaysia, Mauritius, Qatar, Ireland, Poland, Saudi Arabia, Singapore, Swaziland, Trinidad and Tobago, the United Arab Emirates, the United Kingdom, and Zimbabwe.
Hundreds and thousands Hundreds and thousands used incorrectly instead of hundreds of thousands to mean "an indefinite but emphatically large number".
