Update credit card details

For a Microsoft 365 home subscription, the subscription stays tied to the country/region and currency where it was originally purchased. Changing the account address or region does not convert an existing subscription from ZAR to CAD.

To fix this:

1. Cancel the current Microsoft 365 subscription, or wait for it to expire.
2. Make sure the Microsoft account country/region is set to Canada.
3. Add the new Canadian payment method from the Payment options page by selecting Add a new payment method.
4. After the old subscription is fully gone, purchase a new Microsoft 365 subscription in Canada so billing is charged in CAD.

Important details:

• If the subscription was purchased in South Africa, it continues to use that region and currency until the subscription ends.
• A payment method for another country requires the account country/region to be changed first.
• If a region change is blocked, possible reasons include changing region within the last three months, an account suspension, or an active balance due.
• For adding a new card, entering the postal code with and without spaces can help if the card is rejected.

To update the account payment methods:

• Go to Payment options: https://account.microsoft.com/billing/payments
• To change account region: select Your info then Edit profile info from https://account.microsoft.com/profile/
