Machine Readable Zone (MRZ)

Overview

The Machine Readable Zone (MRZ) is the section of a passport or travel document that encodes identity details in a standardized format readable by scanners. Defined under ICAO 9303 standards, MRZ ensures consistent, machine-readable identity verification across borders.Financial institutions and ID verification providers use MRZ scanning to authenticate passports during KYC processes. It improves efficiency, reduces errors, and helps detect fraudulent documents.With growing demand for remote onboarding, MRZ-based verification is increasingly integrated into IDV solutions. Regulators accept MRZ checks as a reliable method of confirming identity, provided they are paired with authenticity checks to detect tampering.
