Be careful how you pay your CC bills too. Don't use the outside mailboxes, go inside of the post office to mail bills or pay with an electronic payment/bill type system.
I had my card number taken a few years ago and I couldn't figure out how they got the number. Then someone on Nextdoor reported a van at my nearby post office pulling letters out of the outside mailbox with a wire + sticky tape. The van took off when they saw the person, only a description of the van, no plate visible.
I know it was that type of credit card/ID theft that got me, the credit card company never received my payment for that month.
