NinUtilsNorway

Util methods for Nin (National identifier number) in Norway

Methods
Name Summary
GetAge(System.String nin, NinUtilsNorway.IDateTimeNowProvider nowTimeProvider) Calculates age from Nin
GetBirthDateFromNin(System.String nin) Calculates birth date from nin based on rules from https://www.skatteetaten.no/person/folkeregister/fodsel-og-navnevalg/barn-fodt-i-norge/fodselsnummer/|
GetControlDigitsForNin(System.String)
GetGender(System.String nin) Resolves gender from nin. Rule is that the first six digits are the birth date DDMMYYYY followed by 3 'individual digits' (individnummer) and finally two control digits (kontrollsiffer). The third digit of 'individual digits' are the indicator for gender. If even number, female individual, if odd number, male individual.
IsDNumber(System.String nin) Returns true if a person is having a D-number. A d-number is given to foreign workers in Norway as a temporary identifier during their work period. It is similar to a ordinary Nin (fødselsnummer), but for the first digit in the nin, we add 4. This gives 4,5,6,7 as possible digits for the first digits. A lot of other characteristics of D-number are similar to ordinary Nin, including the two control digits follow same rules.
IsDufNumber(System.String, NinUtilsNorway.IDateTimeNowProvider) Checks if this is a DUF-number. These numbers are given by UDI The check is only checking it is a number with 12 digits. The number must also reside in UDI data systems, which this method do not check.
IsFHNumber(System.String nin) FH numbers are developed by KITH as a proposal established as a standard 18.01.2010. It is similar to Nin fødselsnumre with 11 digits, and the first digit is 8 or 9. The numbers in position 2 - 9 are generated as random numbers. This standard conceals also gender, birthdate or which order the number is provided. The algorithms allows about 200 million numbers minus 17% of these due to incorrect control digits (last two digits). Examples of people getting a FH-number are tourists, newborn (infants), unconcious people not identified, unidentified people or similar reasons that a fødselsnummer Nin or D-Number is not available.
IsHelpNumber(System.String nin, System.Boolean useEightNineConventionFirstDigitConvention) Checks if this is a help number H-number. The default convention for H-number is that it we add the number 4 to the third digit
IsValidNin(System.String nin) Calculates validity of Nin according to modulo 11 algorithm.
