If you are experiencing trouble with your local mail delivery, it is best to first contact your local post office with your concerns. Because of the Postal Reorganization Act, the United States Postal Service (USPS) is an independent federal agency. I have no direct jurisdiction over this agency and am limited in what I can do. Hoping to be of some assistance, however, I have provided the web site for the USPS. This web site has helpful information, including a place where you can locate the address and/or phone numbers for your local post office.
