Why Choose Our National ID API

We don't just read text; we understand the structure of government documents, tuned for global variances from Bucharest to Bangkok.

Smart Field Logic

Advanced heuristic rules for complex IDs, automatically parsing composite fields like Place of Birth and issuing authorities.

Multi-line Address

Intelligently concatenates multi-line addresses (Region, City, Street) into a single, clean string for database storage.

Global Coverage

Optimized for diverse layouts across North America, Europe, LATAM, and APAC, supporting 200+ territories.

GDPR Compliant

Strict privacy design. Images are processed in-memory and purged immediately. Fully compliant with EU data protection laws.

Personal Number Parsing

Accurate extraction of unique identifiers (CNP, SSN, NRIC, etc.) crucial for banking and KYC duplicate checks.

Structured JSON

Transforms chaotic ID card layouts into standardized JSON with separate fields for Series, Number, and Dates.

Issuing Authority

Extracts the exact government body that issued the document, vital for fraud validation workflows.

Hybrid VIZ + MRZ AI

Combines Vision AI for unstructured visual zones with strict check-digit validation for Machine Readable Zones (MRZ).
