Marine Corps Recruit Depot San Diego operates under dedicated ZIP code 92140 in San Diego County, California. Commissioned on December 1, 1921, this is the oldest operational Marine Corps base on the West Coast. Recruit training relocated here from Mare Island in 1923, and since then the facility has transformed over 1.5 million young Americans into Marines. The depot trains roughly 16,000 recruits annually, serving as the boot camp for all enlisted Marines recruited west of the Mississippi River.
The 0.63-square-mile installation sits in the Midway District of Western San Diego, bounded by Interstate 5 and the harbor. The 2020 Census counted 2,183 residents with a strikingly young median age of 19.2 years, reflecting the recruit population. Approximately 95% live in non-institutional group quarters (barracks), with only 22 housing units on base for permanent staff and their families. In a historic milestone, the first female recruits completed boot camp here in April 2021.
Postal records identify 777 distinct delivery points, an unusually high count for a training facility, reflecting the extensive administrative infrastructure supporting recruit processing. Mail routes through the post office on Belleau Wood Avenue, named for the famous 1918 World War I battle where Marines earned their legendary reputation. This unique postal designation has served the depot for more than two decades. San Diego is the valid mailing city.
