Stripe Checkout The card number is incorrect.

The card number entered by the customer is incorrect.

Understanding Stripe Checkout

Stripe Checkout is a prebuilt, hosted payment page optimized for conversion. It allows businesses to accept payments online with ease, providing a seamless experience for customers. Stripe Checkout handles all the complexities of payment processing, including security and compliance, so developers can focus on building their applications.

Identifying the Symptom

When using Stripe Checkout, you may encounter the error code incorrect_number. This error indicates that the card number entered by the customer is incorrect. The symptom is typically observed when a customer attempts to make a payment, and the transaction fails with an error message.

Common Observations

  • Payment form displays an error message.
  • Transaction does not proceed to completion.

Exploring the Issue

The incorrect_number error is triggered when the card number provided does not pass the validation checks. This could be due to a typo, an incomplete number, or an entirely incorrect card number. Stripe performs a Luhn check to validate the card number format.

Technical Explanation

The Luhn algorithm is a simple checksum formula used to validate a variety of identification numbers, including credit card numbers. If the card number fails this check, Stripe returns the incorrect_number error.

Steps to Fix the Issue

To resolve the incorrect_number error, follow these steps:

Step 1: Verify Card Number

Ensure that the customer has entered the correct card number. Ask them to double-check the digits and re-enter the number if necessary.

Step 2: Implement Client-Side Validation

Implement client-side validation to catch incorrect card numbers before they are submitted. Use libraries like jQuery Validation or Parsley.js to validate the card number format.

Step 3: Use Stripe Elements

Consider using Stripe Elements, which provides prebuilt UI components for card input. These components include built-in validation to reduce errors.

Step 4: Log and Monitor Errors

Implement logging to capture instances of the incorrect_number error. Use tools like Sentry or LogRocket to monitor and analyze error patterns.

Conclusion

By following these steps, you can effectively address the incorrect_number error in Stripe Checkout. Ensuring accurate card number entry and implementing robust validation will enhance the payment experience for your customers.
