Open the BMO app

Launch the BMO mobile banking app on your iPhone or Android device. Sign in with your credentials.

2

Find the activation prompt

Look for a notification or banner prompting you to activate your new card. You can also navigate to the card management section.

Once activated, you can manage your card settings, including online purchase permissions, directly in the app.

For some BMO debit cards, online activation enables the card but you still need to visit a BMO ATM to set or change your PIN before making ATM withdrawals or debit purchases requiring PIN entry.
If you do not see an activation option in your online banking or app, wait 24 to 48 hours after receiving your card. The card must be fully processed in BMO’s system before online activation becomes available.

​
Troubleshooting Online Activation

Ensure your card was mailed to the correct address. If you recently moved, your card may be at your old address. Contact BMO customer service at 1-800-363-9992 for help.
