Postage stamp

Reader's Guide

The invention of the postage stamp revolutionized postal systems worldwide by simplifying the prepayment of postage and enabling uniform rates based on weight. The United Kingdom remains unique in omitting its name from stamps, using the monarch's image instead. Stamps have become collectible items, with philately studying their history and mailing systems. The revenues from stamp sales, including purchases by collectors who never use them for postage, can provide net profit to issuing agencies.

Origins and the Birth of the Adhesive Stamp

Under that legislation, Congress established a rate structure hinging entirely on what was called the "distance zone"—how far a letter traveled from the post office where it entered the system to its ultimate destination. Larger letters attracted double or triple rates, and shipments requiring ocean transport, such as mail bound for Hawaii, carried an extra per-letter ship fee rather than a weight-based charge. That year the United States issued its very first postage stamps, marking the transition from manual notation to a standardized adhesive system.

The Paradox of a Stubbornly Stable Real Cost

One of the most striking patterns in American postal history is that the inflation-adjusted cost of a first-class stamp has remained remarkably steady over more than a century. From the mid-nineteenth century through 1968, the nominal rate barely budged. After 1968, small periodic increases were authorized, and since the early 1980s the stamp price has tracked the consumer price index almost in lockstep. Yet the early twentieth century tells a different story in nominal terms: a single-penny shift could represent a dramatic percentage jump. In a remarkable reversal, the price actually fell in 2016, dropping from 49 cents to 47 cents when a temporary "exigent surcharge" expired. That decrease marked the first time in 97 years—and only the fourth in the agency's entire history—that a stamp became cheaper.

Parcel Post and the Absurdities of Early Regulation

The new service was hailed as a tremendous economic stimulant, opening a world of opportunities for farmers and merchants alike. But the regulatory framework was so thin that extraordinary situations arose. She survived the journey, but the episode prompted officials to clarify the rules and explicitly prohibit human transport via parcel post.

Modern Pricing Architecture and Global Standing

In 2007, First Class Mail pricing was restructured to incorporate shape-based, dimensional-weight pricing rather than relying solely on weight, aligning postage with the sorting machinery in use.
