Book Number

The Book Number is an identifier used in passports distinct from the primary passport number. While not all countries use a Book Number, those that do include it as an additional measure to track passport booklets.

  • Book Number: Refers to the batch or series of passport booklets and may be the same for multiple individuals if they received their passport from the same batch or series.


  • Helps in inventory and batch tracking of passport booklets.

  • Can assist in validating the authenticity of a passport.
