Naval Support Activity New Orleans operated under dedicated ZIP code 70142 in Orleans Parish, serving the Navy's historic Westbank facility in the Algiers district. The Naval presence in Algiers began in 1901 when the U.S. Naval Station was formally established with the arrival of Naval Dry Dock YFD-2. For more than a century, the installation served missions ranging from ship repair to sailor training during World War II, when thousands of vessels received final outfitting before shipping out. At its peak, the base employed over 4,000 people with a $142 million annual payroll. This postal designation served the installation for more than two decades.
The Navy closed the Naval Support Activity in September 2011 as a result of the 2005 Base Realignment and Closure round, ending 110 years of continuous military presence. The 156-acre zone is now known as Federal City and is undergoing redevelopment. Census Business Patterns data still shows 3 establishments with 26 employees in this ZIP. Mail addressed to New Orleans, LA 70142 should be verified, as the original naval facility no longer operates.
