The United States Postal Service (USPS) uses standardized two-letter abbreviations for each state to streamline mail delivery. When addressing mail, it’s essential to use the correct abbreviation to ensure your letter or package reaches its destination promptly. So, What State Is Ar? AR stands for Arkansas.
This system of abbreviations wasn’t always in place. It evolved over time to accommodate the growing volume of mail and the limitations of early addressing equipment. Let’s delve into the history and purpose of these abbreviations.
The History of State Abbreviations
Prior to the implementation of the ZIP Code system, the Post Office Department (now the USPS) preferred that state names be written out in full. This practice aimed to minimize confusion. However, the introduction of the five-digit ZIP Code on July 1, 1963, necessitated a change.
Most addressing equipment at the time could only handle 23 characters (including spaces) on the bottom line of an address. To create enough space for the ZIP Code, state names needed to be shortened.
The initial list of abbreviations, released in June 1963, still contained many three- and four-letter abbreviations, which were too long. The USPS finalized the current two-letter abbreviations in October 1963. The abbreviation for Nebraska was changed from NB to NE in 1969 to prevent confusion with New Brunswick, Canada, marking the only change since then.
