About ZIP Code 90840

California State University, Long Beach operates under dedicated ZIP code 90840 in Los Angeles County. The university traces its origins to Assembly Bill 8 in 1949, which established Los Angeles-Orange County State College to serve the growing population of both counties. Classes began September 28, 1949 with 169 students and 13 faculty. The 322-acre campus, the second largest in the CSU system, sits on land known to its original peoples as Puvungna. CSULB became a university in 1972 and today enrolls over 40,000 students. This unique ZIP has served the campus for over two decades.

The 0.04-square-mile postal boundary represents a focused portion of the larger campus. One hundred thirty ZIP+4 codes route mail to campus facilities, though no specific building names appear in postal records. Census data shows minimal residential population (8 persons), reflecting this ZIP's focus on academic operations rather than student housing, which uses adjacent postal designations.
