About
Built by people who needed it.
ibanchecker.cash started because reliable, developer-friendly IBAN validation simply did not exist as a free tool. Most validators either gave no explanation when an IBAN failed, or locked useful features behind expensive APIs.
We built the tool we wished existed: instant validation with full breakdowns, bank lookups across 84 countries, bulk processing, smart extraction, and a clean API for developers. No IBAN is ever stored.
The free checker stays free. The API is priced fairly. 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.
