The RFD is a government mail service, where mail carriers travel rural routes to deliver and pickup mail from roadside mail boxes. As of 2022, the USPS has around 133,000 mail carriers serving around 80,000 rural mail routes.
Many people even today have rural free mail delivery rather than paying a monthly fee for a post office box and driving long distances to pick up the mail or mail a letter. The rural free delivery, or RFD, was started in 1902. The US Post Office Department began to experiment with the concept as early as 1890, but the implementation was slow, and it was not adopted nationwide until 1902.
Sheridan was one of the first areas where the RFD was established in Wyoming.
