Honoring Our Legacy; Inspiring Our Future

Long before the American colonies won their independence from Britain and became the United States, there was the postal service. In fact, the mail is so intertwined with our nation’s past, it has been said that the history of the United States is the history of the Post Office.

250 Years of History

Colonial Period: 1775 – 1801

In 1737, at the age of 31, Benjamin Franklin was appointed by the British Postal System as the Post Officer at Philadelphia, PA. Nearly 16 years later, in 1753, Franklin—now as Deputy Postmaster General—was tasked with regulating Post Offices and bringing the officers to account.(1) As he visited Post Offices and audited their accounts, Franklin set the precedent for periodic inspections that postal inspectors still carry out today. During these visits, Franklin also applied what we now recognize as his personal genius by making postal routes more efficient and creating better accounting methods. Franklin also established new Post Offices to keep pace with the growth of the colonies.

Train Robberies and Mail Fraud: 1860 – 1900

Organized Crime and Illegal Schemes: 1900 – 1954

Not all criminals directly attacked the mail by robbing stagecoaches or trains. By the late 1800s and early 1900s, extortion groups like the Black Hand Society terrorized hundreds of citizens with threatening letters that demanded payment—or else!

Postal Inspectors and Postal Police: 1954 – 2000

In 1954, the title Post Office Inspector was changed one final time to “United States Postal Inspector.” This was to reflect postal inspectors’ jurisdiction over all operations of the Postal Service and the U.S. Mail, instead of solely Post Offices. Postal inspectors were investigators, recovery personnel, military mail organizers, and law enforcement agents who secured justice for crimes against postal employees and citizens utilizing the mail. Just like the surveyors, special agents, and Post Office inspectors who preceded them, postal inspectors constantly adapted to meet new and unexpected challenges to maintaining the safety and public trust in America’s mail system.
