Greetings!

This is Tin, sorry to hear that you're unable to redeeming your MS Office due to payment verification error. Have you tried to use other browser and check if the issue persists? Or how about clearing cache and cookies? To do that, please press CTRL +SHIFT +DEL then choose the Cache also Cookies, then hit Clear Now. If the issue persists, please try to use other device. And if it's still the same, kindly reach MS Accounts & Billing to check this:

Kindly open this link: https://support.microsoft.com/en-us/contactus/

Ensure that your MS Account has been signed in

Type "Chat with an agent" and hit Enter.

Thank you,

Christine

    Error PaymentAuthenticationVerificationFailed when redeeming or activating a Microsoft 365 product key is typically caused by a payment or billing problem on the Microsoft account being used, even if the bank is not actively blocking the card.

    Troubleshooting steps:

    1. Check and fix payment method on the Microsoft account
      1. Go to the Microsoft account Payment & billing page using the account that is redeeming the key.
      2. In the Pay settings section, select Change how you pay or Fix how you pay.
      3. Confirm that:
        • The payment method is not expired.
        • The billing address and name match what the bank has on file.
        • Any required Strong Customer Authentication (SCA) or multi‑factor approval from the bank has been completed.
      4. Save any changes and try redeeming/activating again.
    2. Complete Strong Customer Authentication if prompted
      • If an email or SMS from the bank is required to approve the charge, follow the instructions and enter the verification code.
      • If a code does not arrive or fails repeatedly, contact the bank to verify the contact details associated with the card and confirm that online recurring/subscription payments to Microsoft are allowed.
    3. Try a different payment method
      • Add a different card or payment method on the same Payment & billing page.
      • Set it as the active payment method and retry the product key redemption or activation.
      • This has resolved the same error for other users by effectively bypassing the failing payment method.
    4. If the error persists
      • Verify there are no other billing issues or outstanding balances on the Services & subscriptions page for the same Microsoft account.
      • If everything appears correct and the error continues, contact Microsoft Support so they can review the subscription and payment status for that account.
