In July 1875, the General Postal Union or "GPU" (later, the Universal Postal Union or "UPU") simplified the handling of international mail. Before the GPU, the United States entered into bilateral postal conventions with numerous other countries to facilitate the exchange of international mail.

The following are copies of many of the postal conventions to which the United States was a party before the GPU. Even though the United States joined the GPU in 1875, some of these bilateral conventions were in effect after 1875 because the other country party to the convention may not yet have joined the GPU or UPU.

Most of these conventions were copied from the United States Statutes at Large, Volumes 16, 17, and 18.
