What is NJ?

NJ is the official two-letter postal abbreviation for the state of New Jersey. This system was standardized by the United States Postal Service (USPS) to streamline mail processing and addressing. Before the adoption of these two-letter codes in 1963, state abbreviations were often inconsistent and could be up to five letters long, leading to potential confusion and delays in mail delivery.

History of the Abbreviation

The current two-letter abbreviations for U.S. states, territories, and possessions were officially implemented on October 1, 1963. Prior to this, New Jersey was commonly abbreviated as 'N.J.' or 'NJ.' The move to a standardized two-letter system aimed to reduce errors and improve the efficiency of automated mail sorting equipment, which was becoming increasingly prevalent. The abbreviation 'NJ' was chosen for New Jersey as a logical and concise representation.
