Use documented Visa, Mastercard, Amex, and Discover test numbers in Stripe’s test environment. These values are intended for sandbox workflows only.
Select a card brand and use the displayed value only with Stripe’s test environment. Stripe documents Visa 4242 4242 4242 4242, Mastercard 5555 5555 5555 4444, American Express 3782 822463 10005, and Discover 6011 1111 1111 1117 as test numbers. Expiration and security-code fields are generated examples.
These are Stripe test values, not general-purpose payment credentials. Use test API keys and test mode only, and follow your processor’s official test-card documentation. Do not submit them to a live payment processor.
