Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Kristen,
To further check on this, can you try to remove 442 in Address Line 2 which may be confusing the address validator if that's meant to be part of the street address. If issue persist, I highly suggest to connect with live Microsoft Support as they are in the best position to further investigate on this given that you've already tried multiple cards, PayPal, incognito mode, and re-entering the address exactly as your bank has it, then the most likely cause is a problem with the billing system's address validation rather than your address.
