About ZIP Code 09730

DPO AE 09730 historically served U.S. Naval Station Argentia in Newfoundland, Canada. The base was established in 1941 under the Destroyers-for-Bases Agreement between the United States and United Kingdom, which granted the U.S. 99-year leases on bases in British territories in exchange for 50 destroyers.

Argentia holds significant historical importance as the site of the August 1941 Atlantic Charter conference, where President Franklin D. Roosevelt and Prime Minister Winston Churchill met aboard warships in Placentia Bay to outline Allied war aims and post-war goals. The meeting occurred before the U.S. officially entered World War II.

The base served as a major anti-submarine warfare center during the Cold War, hosting SOSUS (Sound Surveillance System) operations through NAVFAC Argentia. At its peak, the base employed thousands of U.S. and Canadian military and civilian personnel. Operations were transferred to Canadian Forces in Halifax when the base closed on September 30, 1994.

The ZIP code 09730 remains listed as active in USPS records, though its current specific assignment is unclear. It may serve residual diplomatic functions or have been reassigned to another installation. The AE designation covers Armed Forces Europe, which includes Canada under the U.S. military postal system.
