About this app

Create realistic, checksum-valid IBAN test data for payment forms, fintech apps, and QA — without using customer banking data.

RandomIBAN is an offline-first IBAN generator and validator for developers, testers, QA engineers, students, and fintech teams. Generate synthetic IBANs for 40+ countries, check values with ISO 13616 / MOD-97, and keep reusable samples in a private on-device vault.

IBAN GENERATOR

IBAN REFERENCE
Browse searchable country formats, BBAN structures, lengths, and live examples. Use the visual guide to understand IBAN anatomy and the MOD-97 algorithm.

OPTIONAL PRO
Upgrade to remove ads, save unlimited IBANs, and increase bulk-generation limits. Monthly and yearly plans are available; purchases can be restored through Google Play.

IMPORTANT
Generated values are synthetic and structurally valid, but RandomIBAN does not query banks or account directories. A generated value could coincidentally match an issued account. Use it only in isolated test, demo, or educational environments. Never use generated IBANs for real payments, production customer records, fraud, or impersonation.

RandomIBAN is an independent developer utility and is not affiliated with SWIFT, ISO, or any bank.
