Postal Insignia


Contrary to popular belief, the United States Postal Service has no official motto. However, a number of postal buildings contain inscriptions, the most familiar of which appear in New York City and Washington, D.C.

From “The Letter,” by Dr. Charles W. Eliot, former president of Harvard University, as revised by President Woodrow Wilson.



Mercury, a post rider, and now the eagle have symbolized the U.S. postal system at various times.

In 1782, Postmaster General Ebenezer Hazard used the figure of Mercury, messenger of the gods, in his official seal. Mercury’s feet, helmet, and staff had wings, and he was encircled by an inscription which read, in Latin, “Seal of the Office of the General Messenger.” By 1824 the inscription was changed to read “Seal of the Gen| Post-Office Department,” Mercury’s right hand was raised, and he was standing on top of a globe. By 1829 “America” was written on the globe.

Amos Kendall, in his May 1, 1837, Order of the Postmaster General, moved away from this classical, divine imagery when he directed that the official seal of the Post Office Department portray “a Post Horse in speed, with Mail-bags and rider, encircled by the words ‘Post Office Department, United States of America.’” The energy and effort of a human on a gallant horse served as the seal of the Post Office Department from 1837 through 1970.

When President Nixon signed the Postal Reorganization Act into law on August 12, 1970, the bald eagle became the center of the Postal Service seal. The eagle was poised for flight on a white field, above red and blue bars framing the words “U.S. Mail,” which were in black. The ochre border featured the words “United States Postal Service” on three sides and nine five-pointed stars at the base. The stars had no special symbolism.

On October 12, 1993, Postmaster General Marvin Runyon unveiled a new corporate logo, an eagle’s head in white leaning into the wind, on a blue background. The 1993 corporate logo became a registered trademark on September 12, 1995. It has not replaced the 1970 postal seal as the official seal of the United States Postal Service.
