# Test Cards

> Sandbox test card numbers and the test OTP, organized by card network.

Use these values to exercise the full payment flow in sandbox. They work like real cards but never
move money. More networks will appear here as they're supported.

<Warning>
  **Sandbox only.** These values work only on `sandbox.api.prava.space` /
  `sandbox.collect.prava.space`. They are declined everywhere else.
</Warning>

## Visa

| Card number           | CVV   | Expiry  |

| `4622 9431 2313 7797` | `640` | `12/27` |
| `4622 9431 2313 7805` | `304` | `12/27` |
