Los Alamitos, CA

ZIP code 90721 is a limited-use postal code associated with the Cerritos area of Los Angeles County, rather than a clearly defined residential neighborhood. The major landmarks commonly associated with Cerritos—including Cerritos Center for the Performing Arts, Cerritos Library, Los Cerritos Center, and Cerritos Auto Square—are generally addressed under ZIP code 90703, so they should not be assumed to lie within 90721 itself.
