Guam: Stamps and Postal System

Another territory of the United States, Guam, is located in the north Pacific Ocean. From the 16th to 19th century, Guam was as an important Spanish port, serving as a mid-point between the Philippines and Mexico. As a result of the Spanish-American war, Spain ceded Guam to the United States on December 10, 1898, where it was later used by the U.S. Navy as a supply depot, coaling station and aviation base. The presence of the U.S. Navy created a demand for postage stamps.

Since Guam was controlled by the U.S. Navy, Guam’s postal system was also under the United State’s jurisdiction. Thus, regular issue U.S. postage stamps overprinted with the word “GUAM” were introduced. Shown here is an example of the eleven stamps issued.

Today, as a trust territory of the United States, Guam uses regular issue U.S. postage stamps.
