IBAN Validator

IBAN Validator — Verify International Bank Accounts

The IBAN Validator is a free online tool that checks whether an International Bank Account Number (IBAN) is valid according to the ISO 13616 standard. Enter any IBAN and the tool instantly verifies the check digits using the modular arithmetic algorithm (mod 97), identifies the country, extracts the domestic bank code and account number, and confirms the format matches the expected length for that country. This helps prevent costly errors in international wire transfers.The IBAN system covers over 80 countries worldwide, each with a specific format and length (e.g., Germany has 22 characters, France has 27, Brazil has 29). The validator identifies the country from the first two letters, checks the overall length, validates the two check digits using the mod-97 algorithm defined in ISO 7064, and verifies the structure of the domestic portion (BBAN). The tool clearly displays a breakdown showing the country code, check digits, bank code, branch code, and account number for easy identification.Finance professionals validate IBANs before initiating SWIFT/SEPA transfers to avoid rejected payments and associated fees. Multinational companies verify vendor and employee IBANs in their payment systems. Fintech developers test IBAN validation logic in their applications. Freelancers and exporters verify their own IBAN before sharing it with international clients. Compliance teams validate account information as part of KYC (Know Your Customer) procedures. All validation runs in your browser; no account data is transmitted.IBAN Validator is part of the facilita.tools suite of free financial utilities. Available in Portuguese, English, and Spanish, optimized for desktop and mobile browsers.
