Skatteverket (Sweden) puts a plus symbol when you turn 100. "Between the birth date and the birth number is a hyphen (-), which is replaced by a plus sign (+) in the year the person becomes 100 years old."[1]
Whoever processes the Swedish Identity Number, even if they use YYYYMMDD-SSSC _or_ YYMMDD-SSSC, wouldn't break processing with YYYYMMDD+SSSC or YYMMDD+SSSC - as the '+' is a standardised "give away" as to the age of the person (making the 4-digit YYYY less desirable for processing).

- checkyoursudo 2y agoI feel like (anecdotally) I have been asked more regularly for the full 12 digit number in most systems in the past at least some number of years instead of the 10 digit number. I wonder if more systems are being designed from the start to require millennium and century? I have not been keeping track or anything. I just feel like I am more often required now to input YYYY rather than YY.
- felsokning 2y agoI wonder if that's because there's an assumption that validation has to occur via the Luhn Algorithm (or Modulus 10)[1] on the input-side? Edit: I'd just let BankID handle the validation and store the two-digit year.[2] [1] - https://en.wikipedia.org/wiki/Personal_identity_number_(Sweden)#Checksum https://en.wikipedia.org/wiki/Personal_identity_number_(Swed...
