Test IBAN Generator

Runs in browser Test Data

Structure-valid IBANs (correct length, country format and MOD-97 check digits) so validators accept them, while bank and account parts are random. All generated values are synthetic TEST DATA ONLY and do not belong to real people. These are not real bank accounts.

TEST DATA ONLY — all generated names, contacts, identifiers and numbers are synthetic and do not belong to real people or accounts.

How are test IBANs and card numbers generated?

An IBAN follows a per-country structure from the SWIFT registry (SA: 24 characters, two check digits computed mod 97), and a card number passes the Luhn check digit and starts with a real issuer range. Test values are generated to satisfy exactly those rules — so validators accept them — while their account and card digits are random rather than copied from a real account or card.

A Saudi test IBAN is 24 characters: the country code, two check digits computed mod 97, then the BBAN, a 2-digit bank code and an 18-digit account number, both random.

How to use Test IBAN Generator

  1. Pick a country or Mixed.
  2. Enable "wrong check digits" if you need failing cases.
  3. Set the count and format and press Generate.
  4. Use the valid column to assert your validator's verdict.

Frequently asked questions about Test IBAN Generator

Will validators accept these IBANs?

Yes. Each IBAN has the correct length and BBAN layout for its country and passes the ISO 13616 MOD-97 check, so structural validators return "valid".

Are these real bank accounts?

No. Branch and account digits are random, and the 4-letter bank codes used for Jordan, the UK, Qatar, Kuwait and Bahrain are fictional (TEST, DEMO, MOCK…). Numeric bank codes (Saudi Arabia, UAE, Germany, France, Egypt) are random digits that can match the code of a real bank, so such an IBAN may name a real bank, but its account number is not taken from any real account.

Which countries are supported?

Saudi Arabia, Jordan, UAE, United Kingdom, Germany, France (with a correct RIB key), Egypt, Qatar, Kuwait and Bahrain.

Can I get invalid IBANs for negative tests?

Tick "wrong check digits" to make every fourth row fail the MOD-97 check; the valid column tells you which.

Technical notes

The check digits are computed by moving the country code and "00" to the end, replacing letters with numbers (A=10 … Z=35) and taking 98 minus the remainder modulo 97, exactly as ISO 13616 specifies. The tool re-validates every IBAN it emits.

The example’s check digits, worked out: with “00” in their place the rearranged IBAN leaves 10 mod 97, and 98 − 10 = 88.

  2. 2Replace letters with numbersA=10 … Z=35, so S=28, A=10.23118993526147632783281000
