## Technical Overview & Governing Rules
Generates ISO 13616 compliant test IBANs matching exact country BBAN length, alphanumeric masks, and modulo 97 check digits.

Ideal for payment engineers testing Stripe, Adyen, PayPal, SEPA Direct Debit, and Bacs Direct Debit integrations without using real customer bank credentials.

All generated IBANs pass standard validation routines while using non-allocated test bank code ranges.

## Frequently Asked Questions & Edge Cases
### Q: Are these test IBANs connected to real bank accounts?
**A:** No. They are mathematically synthesized to satisfy ISO 7064 MOD-97 checksum algorithms for QA, staging environments, and integration test suites.

### Q: Can I generate test IBANs programmatically via API?
**A:** Yes! Use our IBAN validator API or official client SDKs (npm install @noorm-mkdad/iban-validator-client) to validate and inspect test accounts in CI/CD.
