The CB purchase number is a key element for identifying a specific transaction carried out with your bank card. This is a unique code that tracks the movements of your bank account and checks that all operations are authorized.

If you don't recognize this number, it's important to take steps to protect your bank account. As a first step, we recommend that you contact your bank to obtain an explanation of this transaction.

It is important to take these steps quickly to avoid fraud or unauthorized use of your bank account. By acting quickly, you can limit the damage and protect your money.
