## Frequently Asked Questions

Is this IBAN (ISO 13616) test data free to use?

Yes. The rows are released under CC0-1.0, so you can copy, modify, and redistribute them without attribution.

Is the data real?

No. All rows are synthetic. Every value is validated by the StanzaAPI engine for this format: it matches the standard structure and passes the format’s check-digit algorithm.

How is the dataset generated?

Deterministically from a fixed seed, so the same size always produces the same rows. That makes it safe to pin in a fixture or CI pipeline.
