Facts About U.S. Postal Abbreviations
The U.S. Postal Service published the first list of official abbreviations in 1874 and that list remained largely unchanged until 1963. That year, the five-digit zip code was introduced. To make room on envelopes and cards, the Post Service shortened all state abbreviations to two letters. Those abbreviations remain in effect today, with one exception. Nebraska's original abbreviation, NB, was changed to NE in 1969, to avoid confusion with New Brunswick, Canada.
