Which of these U.S. states has a postal abbreviation whose letters are not in alphabetical order?
Answer: The United States Postal Service has assigned a two-letter abbreviation to each of the 50 states. Modern two-letter abbreviated codes for the states and territories originated in October 1963, with the issuance of Publication 59: Abbreviations for Use with ZIP Code, three months after the Post Office introduced ZIP codes. Of the states listed, Michigan’s postal abbreviation (MI) is not in alphabetical order. The remaining options Mississippi (MS), Minnesota (MN), and Missouri (MO) all have two-letter abbreviations that are in alphabetical order.
Michigan is a midwestern U.S. state bordering 4 of the Great Lakes. It contains more than 11,000 inland lakes, spread across its lower and upper peninsulas. Its largest city, Detroit, is famed as the seat of the U.S. auto industry, which inspired Diego Rivera’s murals at the Detroit Institute of Arts. Also in Detroit is Hitsville U.S.A., original headquarters of the Motown record company.
