Luhnify
Fast, Zero-PII API for ID & Passport validation.
Luhnify is a Zero-PII REST API for instant identity document, VAT, and ICAO 9303 passport checksum validation. Supporting 200+ countries with <100ms latency, it allows developers to implement compliant onboarding and KYC flows without storing sensitive user data.
Hi Product Hunt! 👋
I built Luhnify to solve a common friction point in software development: validating IDs, VATs, and passports (ICAO 9303) usually meant relying on heavy, slow, or privacy-invasive third-party services.
Luhnify is designed around three core principles:
⚡ Ultra-fast responses: Under 100ms latency.
🔒 Privacy by Design: Zero-PII storage. We perform mathematical checksum and format verification without retaining personal data.
🌍 Global coverage: Built-in validation rules for 200+ countries.
Whether you're building a fintech app, e-commerce checkout, or SaaS onboarding flow, Luhnify keeps your validation logic clean and GDPR-compliant.
I'd love to hear your thoughts on the developer experience, API documentation, or features you'd like to see added!
