not able to update payment method

You cannot change the card number on an existing payment method; add the replacement card as a new payment method, then assign it to your Microsoft 365 subscription.^1^

Add and assign the new card

1. Sign in to Services & subscriptions using the Microsoft account that owns the subscription: https://account.microsoft.com/services
2. Find Microsoft 365, then select Manage.
3. Select Change how you pay.
4. Select Add a new way to pay.
5. Enter the new card number, expiration date, security code, cardholder name, and billing address.
6. Save the card and select it as the payment method for the subscription.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Change your Microsoft subscription payment method and options | Microsoft Support")

Enter the billing details exactly as held by the card issuer. If the card is rejected, try the postal code both with and without spaces; payment methods also vary by region.^1^

If the option is missing

• Past-due subscription: Select Pay now, add the new payment method during that process, and complete the outstanding payment.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Pay for a past-due Microsoft subscription | Microsoft Support")
• Recurring billing is off: Change how you pay will not be available because the subscription is already paid through its end date.
• Prepaid subscription: Its payment method cannot be changed. Add the card to the account and use it when purchasing a new subscription after the prepaid term expires.
• Purchased through another retailer: The retailer manages the subscription and payment method, rather than Microsoft.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Change your Microsoft subscription payment method and options | Microsoft Support")

If the new-card form still will not accept input, try an InPrivate/Incognito browser window or another browser. If it remains unavailable, use Contact Support from the Microsoft payment troubleshooting page and choose the account/billing option; support can inspect account-specific billing restrictions.^4^
