+"""Identiteitskaartnummer, Paspoortnummer (the Dutch passport number).
+
+Each Dutch passport has an unique number of 9 alphanumerical characters.
+The first 2 characters are always letters and the last character is a number.
+The 6 characters in between can be either.
+
+The letter "O" is never used to prevent it from being confused with the number 
"0".
+Zeros are allowed, but are not used in numbers issued after December 2019.
