Razorpay INVALID_CARD_NUMBER error encountered during payment processing.

The card number provided is invalid or incorrectly formatted.

Understanding Razorpay: A Powerful Payment Gateway

Razorpay is a leading payment gateway solution that enables businesses to accept, process, and disburse payments with ease. It offers a suite of payment solutions including credit/debit card processing, UPI, and more, making it a versatile tool for online transactions.

Identifying the Symptom: INVALID_CARD_NUMBER Error

When integrating Razorpay into your application, you might encounter the INVALID_CARD_NUMBER error. This error typically appears when a user attempts to make a payment using a credit or debit card, and the card number is not accepted by the system.

What You See

Users may see a message indicating that the card number is invalid, preventing them from completing the transaction.

Exploring the Issue: Why INVALID_CARD_NUMBER Occurs

The INVALID_CARD_NUMBER error is triggered when the card number entered does not conform to the expected format or is not recognized as a valid card number. This could be due to a typo, an incorrect number of digits, or an unsupported card type.

Common Causes

  • Incorrectly entered card number.
  • Card number does not match any known card issuer.
  • Use of unsupported card type.

Steps to Fix the INVALID_CARD_NUMBER Error

To resolve this issue, follow these steps:

Step 1: Verify Card Number

Ensure that the card number is entered correctly. Double-check for any typos or missing digits. The card number should typically be 16 digits long for most cards.

Step 2: Validate Card Format

Use a card validation tool to check if the card number is valid. You can use online tools like FreeFormatter to validate the card number format.

Step 3: Check Supported Card Types

Ensure that the card type is supported by Razorpay. Refer to the Razorpay documentation to see the list of supported card types.

Step 4: Implement Error Handling

In your application, implement error handling to provide users with clear instructions on how to correct the card number. This could include prompts to re-enter the card number or contact support for assistance.

Conclusion

By following these steps, you can effectively address the INVALID_CARD_NUMBER error in your Razorpay integration, ensuring a smoother payment experience for your users. For more detailed guidance, refer to the Razorpay Documentation.
