The United States Postal System has come a long way since Benjamin Franklin was appointed our first Postmaster General in 1775. The USPS at Riverstone is conveniently located on Bluff's Parkway, behind The Home Depot. Just a few services offered are mail and package shipping and receiving, postage and stamp collecting supplies, cards and gifts. There is a mind-boggling variety of ways to customize and send mail, from packaging to priority mailing services. Post office boxes may be found at the Riverstone USPS. FedEx services are also provided.
