Introduction

This article explains what MRZ is and why Coinlocally requires it for identity verification.

What is MRZ?

MRZ (Machine‑Readable Zone) is a special section on identity documents—especially passports—that contains encoded personal information. It allows automated systems to verify your identity securely and accurately.

Why MRZ is required

• Ensures authenticity of the document
• Prevents fraud
• Speeds up verification
• Required by international compliance standards

Additional notes

• Most modern passports and government IDs include MRZ.
• Documents without MRZ cannot be verified.

Common issues

• Submitting documents from regions where MRZ is not included.
• Uploading photos where the MRZ area is cut off.
