Matching days on a passport and Arstotzkan ID card.
The date of birth (DOB) of an entrant is found on passports, identity cards, and grants of asylum. If an entrant provides two documents containing their date of birth, the dates must be the same. If a discrepancy is found, the entrant cannot clear the discrepancy and to avoid a citation, the inspector must either deny or detain the entrant.
Dates of birth will only be incorrect either by only one digit or completely.
