Random from crypto.getRandomValues. Set a seed to get reproducible data.
- Emails use only example.com, .org and .net, reserved for testing by RFC 2606.
- Phone numbers are random +45 numbers. Denmark has no reserved fictional range that we know of, so a generated number may belong to someone. Do not call or text them.
- Street names are invented; postcodes and towns are real.
- IBANs are synthetic DK numbers with a correct mod 97 checksum and a random registration number. They are not checked against any bank and must not be used for payments.
- Card numbers are only the published test numbers from Stripe and 4111 1111 1111 1111 (Adyen, Braintree). Expiry and CVC are random.
- No CPR numbers are generated, on purpose.
