stripe test card

A Stripe test card is one of the published card numbers Stripe issues for its test mode, letting you run a full checkout without moving any real money. Each number is designed to trigger a specific result — approval, decline, or an authentication challenge — so you can confirm your integration behaves correctly before switching to live keys. Because these numbers are public sandbox tools, they never carry a balance and never contact a real cardholder account.

Key Features

• Standard success number 4242 4242 4242 4242 approves any charge in test mode
• Dedicated decline numbers simulate generic declines, insufficient funds, and expired cards
• 3-D Secure test numbers trigger the authentication step so you can test challenge flows
• Brand coverage for Visa, Mastercard, American Express, Discover, and JCB
• Error-specific numbers for incorrect CVC, processing errors, and lost or stolen responses
• Works across Payment Intents, Checkout, Elements, Stripe.js, and reader simulators
• Safe to reuse indefinitely — test mode never settles a charge or bills a customer

Specs and Compatibility

Every test number follows the standard 16-digit format and accepts any future expiry date, any three-digit CVC, and any postal code, which keeps automated test suites simple. Results are driven by the number itself rather than by the other fields, so you can isolate a single variable in each test run. Pair the numbers with your test-mode publishable and secret keys, keep amounts small and arbitrary, and use Stripe's test clocks when you need to simulate subscription renewals or delayed capture scenarios.

Delivery and Support

Delivery is instant and digital: the reference set appears in your account immediately after checkout, with no physical shipment and nothing to return. If a listed response does not match what you see in your dashboard, contact support within the coverage window and we will review or replace the reference set.

Do Stripe test cards work in live mode?

No. Test numbers are rejected outright once you switch to live API keys, which is exactly what prevents an accidental real charge during development.

Can I use any expiry date and CVC with a test card?

Yes. Any future expiry, any three-digit CVC, and any postal code will pass, except where a number is specifically built to return a CVC or expiry error.
