Irvine, CA

ZIP code 92623 is a PO Box–only postal code associated with Irvine, California, rather than a conventional area with clearly defined neighborhood boundaries. As a result, major landmarks cannot reliably be assigned to the ZIP itself. Notable Irvine destinations nearby include the Irvine Spectrum Center, the Orange County Great Park, and the University of California, Irvine; these are in other parts of the city, not within a distinct 92623 geographic area.
