The ZIP's footprint is essentially non-existent as a geographic area—0.0 square miles—because it functions as a PO Box-only designation embedded within neighboring ZIP 91320, which provides the actual street delivery infrastructure for Newbury Park. The 354 residential delivery points are technically located at Grande Vista Drive and Newbury Road, but residents can also access standard street delivery through the surrounding standard ZIP code. The postal facility here operates as a business-focused service point, with the ratio of business boxes to residential service suggesting this functions primarily for commercial convenience rather than necessity.
The street roster shows an extremely limited geographic scope. Grande Vista Drive dominates with 63 delivery records including unit designations, likely representing a single multi-unit property or building complex. Newbury Road's single record suggests it's referenced for location purposes rather than actual delivery infrastructure. This pattern confirms the ZIP's function as a PO Box facility serving a very specific address range within the broader Newbury Park area.
