Amex test card numbers
Amex is different: 15 digits with a 4-digit CVV (CID). Any future expiry date works in test mode.
| Card number | CVV (CID) | Behaviour |
|---|---|---|
| 3782 8224 6310 005 | 4 digits | Succeeds (Stripe) |
| 3714 4963 5398 431 | 4 digits | Succeeds (Stripe) |
Amex number structure
- Prefixes: 34 and 37.
- Length: 15 digits (never 16).
- Security code: 4-digit CID on the front of the card.
- Luhn: Amex numbers use the same MOD 10 checksum as other networks.
The generator automatically uses 15 digits for BINs starting with 34 or 37. Validate any number with the Luhn validator.
FAQ
- Why is my Amex test number rejected?
- A common cause is using a 16-digit number or a 3-digit CVV. Amex requires 15 digits and a 4-digit CID, and gateways often validate this specially.
- Does Amex support 3D Secure testing?
- Yes. The 3DS flow is triggered by the gateway's test cards, not by the BIN. See our article on 3D Secure testing for details.
