About
Built by people who needed it.
ibanchecker.cash started because most IBAN validators either gave no explanation when a check failed, or locked every useful feature behind expensive, hard-to-evaluate APIs with no real free tier.
We built the tool we wished existed: instant validation with full breakdowns, bank lookups across 92 countries, bulk processing, smart extraction, and a Developer API with a meaningful free tier. No IBAN is ever stored.
The checker tools are free, no login required. The API starts free and scales with transparent monthly pricing. No dark patterns.
The Team
Koray designs, builds, and ships ibanchecker.cash end-to-end. He started the project because a reliable, developer-friendly IBAN validation tool simply didn't exist. His rule: if it's worth building, it's worth finishing.

LinkedInHow We Work
No IBAN storage
Every validation runs in memory and is discarded immediately. We never log, store, or process your IBANs beyond the instant you submit them.
Edge-first
ibanchecker.cash runs on Cloudflare's global edge network. Your request is processed at the data center closest to you — fast, always.
Transparent pricing
The free checker has no hidden limits. API pricing is published openly. No trials that expire, no feature gates that move.
