I know virtual credit card numbers are a thing, but on the other hand I just solve it by having a different CC for subscription payments vs everyday transactions. If the every day card has fraud and I need to change the number, no skin off my back. If the subscription card needs to be changed, I have a convenient list of everyone I need to contact because it sees the exact same charges every month.
