Norway
The Norwegian eleven digit birth number is assigned at birth or registration with the National Population Register. The register is maintained by the Norwegian Tax Office. It is composed of the date of birth (DDMMYY), a three digit individual number, and two check digits. The individual number and the check digits are collectively known as the personal number. The first check digit is calculated as follows:
11 minus the weighted sum modulo 11 of the nine first digits. If the result is 10, the number is invalid and is discarded. If the result is 11, 0 is taken to be the check digit.
The last check digit is calculated in a similar manner:
11 minus the weighted sum modulo 11 of the ten first digits (including the first check digit).
The weights for the first check digit are 3, 7, 6, 1, 8, 9, 4, 5, 2, the weights for the second check digit are 5, 4, 3, 2, 7, 6, 5, 4, 3, 2.
The individual number is selected from a range depending on century of birth: for the years 1854-1899 the range is 500-749, for the years 1900-1999 the range is 000-499, for the years 2000-2039 the range is 500-999.
For the years 1940-1999, the range 900-999 was also used for special purposes, such as adoptions from abroad and immigrants. Women are assigned even individual numbers, men are assigned odd individual numbers. This system allows one to uniquely identify people born between 1854 and 2039. What will happen after 2039 is not decided.
People without permanent residence in Norway will be assigned a D-number upon registration with the population register. The D-number is like a birth number having 40 added to the day of month.

Famous quotes containing the word norway:
“A long time you have been making the trip
From Havre to Hartford, Master Soleil,
Bringing the lights of Norway and all that.”

“Write about winter in the summer. Describe Norway as Ibsen did, from a desk in Italy; describe Dublin as James Joyce did, from a desk in Paris. Willa Cather wrote her prairie novels in New York City; Mark Twain wrote Huckleberry Finn in Hartford, Connecticut. Recently, scholars learned that Walt Whitman rarely left his room.”

When he the ambitious Norway combated.”
