Hello
Thank you for posting in Q&A forum.
Azure doesn’t accept virtual or prepaid cards. Ensure you’re using a valid credit card or debit card. Please refer to the following links: azure-content/articles/billing-credit-card-fails-during-azure-sign-up.md at master · uglide/azure-content · GitHub
Please also ensure that the billing and shipping details in your Microsoft Account Center are complete and valid. Verify that the billing address registered for your credit card matches your bank records. For more details, see the official documentation: Troubleshoot issues when you sign up for a new account in the Azure portal - Microsoft Cost Management | Microsoft Learn
I hope the information above is helpful.
Best Regards,
Yanhong Liu
