Extract structured data from Machine Readable Zones (MRZ) on passports, ID cards, and visas using barKoder’s high-accuracy MRZ parser. Decode document type, name, nationality, date of birth, expiry, and more instantly within your app.
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.
Whether you're verifying identity for onboarding, KYC, access control, or fleet management, barKoder instantly returns clean, labeled fields from a single scan.
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:
{
"first_name": "Alex",
"last_name": "Johnson",
"license_number": "D12345678",
"address": "123 Main St",
"city": "Austin",
"state": "TX",
"zip": "78701",
"dob": "1990-02-12",
"issue_date": "2022-01-01",
"expiry_date": "2030-01-01"
}
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:
