Are these IBANs real and can they receive money?
No. The numbers are syntactically valid - they pass the IBAN check-digit algorithm and look like real accounts - but they are not associated with any actual bank account. Sending money to one will fail at the bank's account-existence check. The generator exists for filling out test forms, validating regex patterns, seeding QA databases, and developing software that needs realistic-looking data without involving real customers.
Is it legal to use generated IBANs in production?
Use them only in development and test environments. Submitting fake IBANs to production payment systems can violate terms of service and, in some jurisdictions, anti-fraud regulations if used to deceive a counterparty. For legitimate testing of payment integrations, use the sandbox-mode IBANs your payment provider supplies - they are designed to flow through their test infrastructure end to end without ever touching real banks.
How does the IBAN check digit work?
The two digits after the country code are computed so that the entire IBAN, treated as a large integer with letters mapped to numbers, is divisible by 97 with a remainder of 1. The generator builds the body first, runs the mod-97 calculation, and inserts the resulting check digits. This means typos in any character will almost always be detected by validators because the divisibility property breaks.
Can I generate IBANs for any country?
The tool supports the official IBAN-using countries with their correct length and BBAN structure - for example 22 characters for the UK, 20 for France, 27 for Germany. Each country has its own format because the BBAN includes locally meaningful bank, branch, and account fields. Pick the country you need from the dropdown and the generator will assemble a valid-format IBAN of the right length.
Is my generated IBAN ever logged or sent to a server?
No. The IBAN is built in your browser using local JavaScript. Nothing is uploaded, recorded, or shared with any third party. You can refresh repeatedly to get new values without leaving any trace on our infrastructure. Even though the data is fake, we treat it the same way as real input - the page does not transmit it back at any point.
Will payment libraries accept these IBANs as valid?
Most libraries check format and the mod-97 check digit, both of which the generator satisfies, so static validation will pass. However, libraries or APIs that perform a network lookup against a bank registry will reject them because the bank or branch code corresponds to no real institution. Use the generator for unit tests against pure validation logic and switch to provider-supplied sandbox IBANs for end-to-end tests.
