How to use Test cards
- 1. Copy a public test PAN. Processor docs are the source of truth.
- 2. Any future expiry / CVV. Usually.
- 3. Generate extra Luhn numbers. For format tests, not charges.
- 4. Stay in test mode. Live + these numbers is fraud-adjacent and will fail or worse.
About this tool
Every PSP publishes numbers that only work in test mode. Collecting them here saves a search. Charging them on production is not a feature.
