How does Mastercard ID Check work?

Each time you make an online purchase using your National Bank Mastercard with a participating merchant, a secure code will be sent to you to verify your identity.

The code will be sent by text or email. You will then have to enter the code in the dedicated window. The code is valid for 5 minutes. You'll have 3 attempts to enter the code correctly. 

Once you have entered the correct code and we've been able to verify that you're the authorized cardholder, the transaction will be finalized.

If you have any questions, please contact Mastercard Customer Service at 1-888-622-2783
