IBANtool is a free, client-side web utility offering two banking tools: an IBAN validator that checks format, length, and MOD 97 check digits per ISO 13616 for 53 countries, and a SWIFT/BIC code lookup that searches 178+ banks across 50+ countries. All validation runs entirely in your browser, so no IBAN or SWIFT data is uploaded to any server, ensuring privacy and no signup required.
What is IBANtool?
IBANtool is a free, browser-based banking utility that provides two core functions: validating International Bank Account Numbers (IBANs) and looking up SWIFT/BIC codes. It takes an IBAN as input and returns a breakdown of country, check digits, and BBAN, or takes a bank name, country, or BIC and decodes the 8- or 11-character code into bank, country, location, and branch details. The tool runs 100% client-side, meaning no financial data is transmitted to any server, and it is developed and maintained by IBANtool.
Key Features
- IBAN Validation — Validates IBAN format, length, and MOD 97 check digits for 53 ISO 13616 country specifications, breaking the IBAN into country, check digits, and BBAN.
- SWIFT/BIC Code Lookup — Searches by bank name, country, or BIC across 178+ banks in 50+ countries, decoding any 8- or 11-character SWIFT code into bank, country, location, and branch.
- 100% Client-Side Processing — All validation and lookup runs in the browser; no tool input is uploaded, ensuring financial data never reaches the application server.
- No Signup Required — Both tools are free to use without registration or account creation.
- Country-Specific IBAN Formats — Provides detailed IBAN format and example pages for 53 countries, including length and structure specifications (e.g., Albania 28 chars, Austria 20 chars).
- Popular Banking Regions — Quick access to SWIFT lookup for major countries like China, US, UK, France, Germany, and more.
Who is it for?
- Individuals sending international wire transfers — Validate an IBAN before sending money to ensure it's correctly formatted and reduce the risk of failed or misdirected payments.
- Businesses and finance teams — Look up SWIFT/BIC codes for banks in different countries to ensure accurate routing of cross-border payments.
- Developers and testers — Use the IBAN validator to check test IBANs or verify the correctness of IBAN generation logic in their own applications.
- Banking customers — Decode a SWIFT code to identify the bank, country, location, and branch before initiating a wire transfer.
What can you do with IBANtool?
- Validate an IBAN before a transfer: Enter an IBAN to instantly verify its format, length, and MOD 97 check digits, and see a breakdown of its components.
- Look up a SWIFT/BIC code: Search by bank name, country, or BIC to find the correct code for a specific bank branch, ensuring your payment reaches the right institution.
- Compare country-specific formats: Use the IBAN format pages to understand the structure and length of IBANs in different countries, such as Germany or China, when planning cross-border payments.
How does IBANtool work?
IBANtool operates entirely in the browser. When you enter an IBAN, the tool runs the MOD 97 algorithm locally to validate the check digits and parses the IBAN structure according to ISO 13616. For SWIFT lookups, the tool searches its built-in database of 178+ banks across 50+ countries to decode the BIC. No data is transmitted to any server, ensuring privacy.
Pricing
IBANtool is completely free to use. Both the IBAN validator and SWIFT code lookup tools are available at no cost, with no signup required.
