when did state abbreviations change to two letters
List of U.S. state abbreviations 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 in July 1963. The purpose, rather than to standardize state abbreviations per se, was to make room in a line of no more than 23 characters for the city, the state, and the ZIP code.[12]
State of the Union George Washington delivered the first regular annual message before a joint session of Congress on January 8, 1790, in New York City, then the provisional U.S. capital. In 1801, Thomas Jefferson discontinued the practice of delivering the address in person, regarding it as too monarchical (similar to the Speech from the Throne). Instead, the address was written and then sent to Congress to be read by a clerk until 1913 when Woodrow Wilson re-established the practice despite some initial controversy. However, there have been exceptions to this rule. Presidents during the latter half of the 20th century[who?] have sent written State of the Union addresses. The last President to do this was Jimmy Carter in 1981, after his defeat by Ronald Reagan and days before his term ended.[9]
