The Naval Weapons Station Seal Beach primarily uses the zip code 90742. This is an entirely separate and distinct zip code dedicated to the military installation itself, not the general public of Seal Beach. While geographically located within the broader Seal Beach area, its postal services are managed independently. It's a common misconception that 90742 is a secondary Seal Beach zip code; however, it's specific to the base.
