can't add credit card

Hello Andrew Lucas

Welcome To Microsoft Q&A Forum.

I understand that you are facing with credit card issue - you tried to update your credit card on a Microsoft account, but nothing worked.

Here are some steps that you can kindly take to help resolve your issue:

Step 1: Clear and Re-enter Details

• Go tohttps://account.microsoft.com/billing/payments
• Remove the old card completely.
• Add the new card with:
  • Exact name as on the card (no honorifics)
  • Matching billing address for the currency region
  • Use Address 2 if Address 1 is too short
  • Avoid abbreviations

Step 2: Use a Different Browser or Device

• Try adding the card from a different browser or incognito mode.
• If you're logged in with a work account, try using a personal Microsoft account instead.

Step 3: Check for UI Rendering Errors

• If the card is accepted but not visible, this may be due to a duplicate display ID rendering bug. The card is added but not shown

Step 4: Contact Microsoft Billing Support

• Reference ICM Incident 643471655 and the backend fix confirmed by engineering on 2025-07-14.
• Use Microsoft Support and select “Contact Support”

Additional Workarounds:

• Use PayPal: If available, PayPal may bypass some of the stricter validation checks.
• Change Billing Admin If you're managing a business account, changing the billing admin can force the system to reallocate a new selling entity, resolving mismatches.

I hope it helps, please feel free to let me know if you need any further assistance.

Thank you for your time!
