There isn’t just a two-letter postal abbreviation for all 50 states, there’s also a regular abbreviation for each state too. Regular state abbreviations came out in 1963, but many were three or more letters in length so it was decided they would be too long to include on envelopes and packages as postal addressing equipment used by the US Postal service couldn’t accommodate these longer states abbreviations along with zip codes.

The California state abbreviation is made up of the first five letters of the state name with a period at the end of the abbreviation: ‘Calif.’, it is one of the longest state abbreviations. California, otherwise know as The Golden State offers plenty of opportunities for those looking to do business in the state, as well as those seeking a better lifestyle and quality of life.
