How to Activate Your My Best Buy Credit Card in Canada

Citibank’s website is currently structured to support American customers only for their online activation needs.

If you live in Canada and have a My Best Buy credit card to activate, then you can contact the same toll-free customer service line for your activation as customers in the United States and Puerto Rico.

When your residence is outside of these areas, then Citibank offers a number that you can call collect to finalize your activation. You can dial 1 (423) 467-6543 to begin this process.

The hours of service in Canada are also based on your time zone.

If you live internationally, then you will want to base your available contact times to the nearest North American time zone to your location.

How to Finalize the Activation Process

Today’s My Best Buy credit card from Citibank features chip and pin technology for better security. You still need to sign the back of your card for locations where a signature-only transaction is available.

Then make sure to read your cardholder agreement carefully. There are some excellent rewards you can earn by using your My Best Buy credit card for purchases, but specific terms and conditions apply.

For more information about this opportunity or to begin the activation process, you can access your account through the Citibank website.
