Context & Background
Originally known as Camp Miramar and later NAS Miramar, this world-famous installation was transferred to the Marine Corps in 1997. Today, MCAS Miramar serves as the home to the 3rd Marine Aircraft Wing and over 15,000 active-duty service members and their families. The dedicated 92145 ZIP code was established to manage the massive influx of official defense correspondence, personal mail, and heavy freight shipments.
Navigating this vast 23,000-acre installation requires precise geographical data. While the base is geographically surrounded by the San Diego neighborhoods of Mira Mesa, Scripps Ranch, and University City, the 92145 ZIP code operates independently of municipal postal routes to maintain military security standards.
Impact & Utility
Mailing items to a highly secure military installation requires strict adherence to standardized postal formats. Incorrectly addressed letters or packages can result in significant transit delays or immediate return-to-sender status by base security.
When sending mail to personnel stationed at MCAS Miramar, utilize the following standardized format:
- Recipient's Full Name (Rank/Grade is highly recommended)
- Unit/Department/Command Name (e.g., Marine Aircraft Group 11)
- Box Number or Building Number
- San Diego, CA 92145
For commercial shipping (UPS, FedEx, DHL), ensure the physical gate address is clearly listed alongside the 92145 ZIP code. High-security deliveries must proceed through designated commercial gates, which require pre-clearance and specific routing coordinates within the 92145 sector.
