"""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.
