Why? I did that once, and it was a huge pain. But the cards work just as well no matter what they think your address of record is. Now I just don't change it.

So you use your old address as your billing address? Aren't you worried about the new resident of your old address receiving official communications intended for you?

In USA, you can file change of address forms with USPS. Any and all financial firms will get that change within a few months, and over that period USPS will forward automatically.

No, because that is my parents.

If I was worried, I'd tell the payment cards to stop sending me mail.
