Normalized Attributes
These attributes form part of our normalized model, a standardized set used across providers. Trinsic normalizes this for you and lets you know when a property is available for each provider.

Field	Availability	Notes
`person.givenName`	Always	-
`person.familyName`	Always	-
`person.fullName`	Always	-
`person.dateOfBirth`	Sometimes	If available
`person.phoneNumber`	Sometimes	If authenticated with MobileID. Is not returned from a BankID.

Field	Optional	Description	Example Values
`fullName`	Yes	The full name of the individual.	Ove Henriksen
`dateOfBirth`	Yes	The date of birth of the individual.	1943-08-15
`personalIdentificationCode`	Yes	The 11-digit Finnish Personal Identification Code (Henkilötunnus) of the verified individual. This is in the format DDMMYYCZZZQ, where: - DDMMYY is the date of birth - C is a symbol which determines the century of birth - ZZZ is an individual number, indicating gender - Q is a checksum character If ZZZ is even, the individual is female. If ZZZ is odd, the individual is male. If C is '+', the individual was born in the 19th century (1800-1899). If C is '-', 'U', 'V', 'W', 'X', or 'Y', the individual was born in the 20th century (1900-1999). If C is 'A', 'B', 'C', 'D', 'E', or 'F', the individual was born in the 21st century (2000-2099).	300690-543X
