You can change the physical card number at any time through settings, it does not change automagically with each transaction— I have one and have changed it a couple times a year for security porpoises— warm regards

You can change the virtual card number. The **physical** card number imprinted on the Titanium cards mag stripe cannot be changed without replacing the card.
