Rejected Four-Letter Zip Code Abbreviations

Beginning in 1975, the U.S. Postal Service experimented with easy-to-remember four-letter words to represent the 50 states and five U.S. Territories.

The abbreviations included CORN for California, NADA for Nevada, OREO for Oregon and SCAR for South Carolina.

The program never caught on and was replaced with the current two-letter abbreviations in 1979.
