what do the digits in a phone number mean
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.)
.properties Each parameter is stored as a pair of strings, one storing the name of the parameter (called the key), and the other storing the value.
ICD-10 Work on ICD-10 began in 1983 and was completed in 1992.[1]
Vehicle identification number VINs were first used in 1954.[1] From 1954 to 1981, there was no accepted standard for these numbers, so different manufacturers used different formats.
