Api

Method	arguments	returned value	throws
parse	ssn: string | number : You may provide your ssn in various formats : a number with 15 digits, a string, with or without spaces, or any other delimiting character	an object containing information about the ssn owner	will throw if ssn is not correctly formated or if control key does not match. Will not throw if information provided does not make sense, information will simply be marked as "unknown". Eg: parse("0 ...").gender = { unknown: true }
validate	ssn: string | number	boolean (this is only a convenience function, it calls parse under the hood in a try catch block)	never
getControlKey	partialSSN: string | number : The first 13 characters of the ssn	string : the control key (2 digits between "01" and "97")	will throw if ssn is not correctly formated
make	params: { gender: string? | number?, month: string? | number?, year: string? | number?, place: string? | number?, rank: string? | number?, controlKey: string? | number? }	string Mostly useful for tests, this function creates an SSN with the given params. If controlKey is not provided it is auto filled with a valid value. All named parameters of the function are optionnal.
format	params: string | number	string it prints an SSN nicely with spaces	will throw if ssn is not correctly formated
