About

barKoder MRZ Parser

A Machine Readable Zone (MRZ) is a section on identity documents – such as passports, ID cards, visas, residence permits, and other travel documents – that contains encoded personal information in a standardized format.

barKoder's parser decodes and organizes the AAMVA data into structured fields which are then returned in a developer-friendly JSON format, with key-value pairs mapped to the AAMVA data elements, like so:

code snippet JSON:

What is Machine Readable Zone?

The Machine Readable Zone (MRZ) is a standardized format used globally on identity documents such as passports, visas, and some national ID cards. It allows machines to quickly and accurately read personal data using optical character recognition (OCR) technology.

Most passports and machine-readable travel documents (MRTDs) include a Machine Readable Zone (MRZ) that encodes key personal and document data in a standardized format defined by the ICAO Document 9303. The MRZ typically appears on the bottom of the identity page and includes:

  • Full name (first, middle, last)
  • Document number (DL/ID)
  • Nationality
  • Date of birth
  • Gender
  • Document expiration date
  • Issuing country or authority
  • Check digits for data validation
