How can I update my card on file?

To update your credit card on file for your AWS account, you can follow these steps:

1. Sign in to the AWS Management Console and open the AWS Billing and Cost Management console.

2. In the navigation pane, select "Payment preferences".

3. Find the credit card you want to edit and choose "Edit" next to it.

4. Update the fields you want to change. This can include the name, address, phone number, or other details associated with the card.

5. After making your changes, scroll to the bottom of the page and select "Update" or "Save changes" to confirm your modifications.

It's important to note that after updating your card information, you may need to verify the card again. If you encounter any issues or continue to receive notifications about an expired card after updating, you might want to check if the card needs verification in the Payment preferences page.

Remember to ensure that the expiration date on your card is current to avoid any service interruptions. If you're still experiencing problems after following these steps, it may be helpful to contact AWS Billing Support for further assistance.
