Birth number is a unique numerical identifier assigned to residents of the Czech Republic and Slovakia.
The birth number is regulated in Act No.133/2000 Coll., on population registration. The date of birth and sex of the person concerned can be derived from the birth number. In the Czech Republic, the birth number belongs to personal data. In many other countries similar numerical identifiers are used, and the same format as in the Czech Republic is used for birth numbers in Slovakia.
