What is a .mrz file?

File Extension Details

The MRZ (Machine Readable Zone) file format is a specialized data structure used primarily in identity documents such as passports, visas, and national ID cards. It contains specific biographical information encoded in a standardized format defined by the International Civil Aviation Organization (ICAO) Document 9303. An MRZ file typically stores the text found at the bottom of a passport data page, which includes the holder's name, document number, nationality, date of birth, sex, and expiration date, along with various check digits to ensure data integrity. While not a traditional file format used for general storage, MRZ data is often saved in text or proprietary data files by identity verification software, border control systems, and mobile scanning applications. These files are essential for automated identity verification, allowing systems to quickly parse and validate personal information without manual data entry. The format is strictly structured, relying on specific character sets and fixed-width fields to ensure global interoperability between different countries' scanning hardware and database systems.
