If you are using a mail service to forward your mail you can not file a change of address for that address and expect it to go through - - won't happen. In fact it is laid out in the directions you got from the mail service when you signed up for the service, and it is a requirement of the post office that they do so. A good reason to save the paperwork you get from the mail forwarding company.
You have to personally notify each company/individual of the change of address. If you do most of your things via the web, it really isn't hard to do.
