That's what I have always understood.
But isn't the tracking specific to the suspect/s?

Can you track every single customer at my debit card company, in case a child abductor decides to call them one day?

Yes is suspect specfic. A request is made for certain numbers not all phone numbers.

I can only speak to telephony and the phone numbers not credit card processing.
