A Stripe test CVV code is any three-digit number you pick, such as 123, when you pay with a Stripe test card in test mode. Stripe does not check that value against a real card issuer, so 123, 456, or 000 all pass. American Express test cards take four digits instead of three.

Stripe Test CVV Number: A Comprehensive Guide

What CVV should you use for Stripe test cards?

Use 123 for Visa, Mastercard, Discover, and most other test cards. Use 1234 for American Express test cards. Pair the code with any future expiry date and any postal code, since Stripe's test mode ignores those fields too.

• Visa test card: 4242 4242 4242 4242 with CVV 123
• Mastercard test card: 5555 5555 5555 4444 with CVV 123
• Amex test card: 3782 822463 10005 with CVV 1234
• Discover test card: 6011 1111 1111 1117 with CVV 123

Stripe's documentation states that any three-digit CVC works with its standard test card numbers. The CVV field exists in test mode so your checkout form can validate input length and format, not so Stripe can verify a security code.

Stripe CVV Test Card: Guide to Purchasing

Why any CVV works in Stripe test mode

Test mode sends payment data to a Stripe simulator, not to a card network. A real CVV check happens at the issuing bank, and the bank is never contacted when you use a test key. Stripe reserves specific card number ranges for testing, and those numbers cannot be charged in live mode.

Stripe CVV Checker: A Guide to Buying CVV

The CVV field still matters for your integration. Your form should collect three or four digits, reject letters, and pass the value to Stripe in the cvc parameter. A test payment confirms that path works before you switch to live keys.

Test mode vs live mode

Test mode uses API keys that start with pk_test_ and sk_test_. Live mode uses pk_live_ and sk_live_ keys, and test card numbers are rejected there. If a test card number fails with a live key, the key is the problem, not the CVV.

How to test a CVV failure in Stripe

Stripe publishes test card numbers that trigger specific decline codes. Use card number 4000 0000 0000 0127 with any CVV to get an incorrect_cvc decline. Card number 4000 0000 0000 0101 returns a decline where the CVC check fails.

These cards let you test error handling in your checkout without waiting for a real bank decline. Confirm that your app shows a clear message, logs the decline code, and lets the buyer retry. Test the success path with 4242 4242 4242 4242 and the failure path with a CVC decline card in the same session.

• incorrect_cvc: 4000 0000 0000 0127
• cvc_check fails: 4000 0000 0000 0101
• generic decline: 4000 0000 0000 0002
• expired card: 4000 0000 0000 0069
• insufficient funds: 4000 0000 0000 9995

Do 3D Secure test cards change the CVV rule?

No. 3D Secure test cards, such as 4000 0027 6000 3184, still accept any three-digit CVV. The difference is that the payment triggers an authentication step, where you choose to complete or fail the challenge in the test modal.

Does Stripe ever reject a test CVV?

Stripe rejects a test CVV only when the format is wrong, for example two digits or letters. Length checks happen on the client, through Stripe Elements or your own validation, before the value reaches the API. If Elements shows a CVC error, the fix is in the form configuration, not the test card.

One exception: some test cards for specific error scenarios expect a matching CVV pattern. Stripe's test documentation lists those cases, and they are rare. For routine checkout testing, 123 is enough.

Where to find the official Stripe test card list

The Stripe Docs page titled "Testing" holds the current list of test card numbers, decline codes, and 3D Secure cards. The Stripe Dashboard also links to it from the Developers section. Check that page before you build a test suite, since Stripe adds cards over time.

Store test card data in a config file, not in production code. Keep test keys out of your live deployment, and rotate any key that leaks into a public repository.

Frequently asked questions

Can I use 000 as a Stripe test CVV?

Yes. Any three digits pass with standard test cards, including 000. Use 1234 for Amex.

Is a test CVV the same as a real CVV?

No. A real CVV is printed on a physical card and checked by the issuer. A test CVV is a placeholder that only works in Stripe test mode.

Why does my test card get declined with a CVV error?

You are likely using a decline test card such as 4000 0000 0000 0127 on purpose, or you typed fewer than three digits. Switch to 4242 4242 4242 4242 with CVV 123 to confirm the success path.
