The code that gives a give name consists of two digits (a person can not have more than 2 given names). The significance of the figures is shown in the following example.
"Eva Mia" - Mia is the given name, marked with 20. 2 indicates that the second first name is the given name.
"Kjell Olof Stig" - Kjell Olof is a given name, marked with 12. 12 indicates that the first and second first name is the given name.
"Hedvig Britt-Marie" - Britt-Marie is a given name, marked with 23 (first name with a hyphen is considered two names). 2 and 3 indicate that the second and third first names constitute the given name.
If there is no code for a given name, then there is no given name stated in the population register and thus not in SPAR.
