Avalon sits on Santa Catalina Island, 22 miles off the coast of Los Angeles County. This is a PO Box Only Zone where nearly everyone relies on the post office for mail delivery across the island's 75 square miles. The Avalon post office maintains 1,362 PO Boxes for a year-round population of 3,715 residents living in 1,493 households. That's a 91% adoption rate.
Why doesn't street delivery exist here? Island logistics make traditional carrier routes impractical. While postal records list 58 street names (Whittley Avenue, Metropole Avenue, Crescent Avenue, Pebbly Beach Road), these addresses primarily serve as location references. One rural route and one city carrier route handle limited delivery to specific locations, but most mail goes to PO Boxes. Ferry access is the only way on or off the island, which shapes every aspect of postal service.
Seasonal patterns define Avalon's housing market. Of 2,441 total housing units, 728 (30%) sit vacant for seasonal use. Median home values reach $902,800, while median gross rent hits $2,076 monthly. The year-round population of 3,715 swells dramatically during summer months when vacation homes fill and tourists arrive. The median age of 40.3 suggests a mix of working residents and middle-aged homeowners.
Avalon's economy runs on tourism and transportation. Of the workforce, 1,869 people work in transportation, warehousing, and utilities (the ferry and related services). Another 339 work in accommodation and food services. There are 203 business establishments employing 2,279 people total. Street names tell the island's story: Spanish heritage in Camino del Monte and Calle del Sol, beach geography in Pebbly Beach Road and Descanso Beach, historic references in Banning Drive and Wrigley Terrace Road.
USPS recognizes two alternative names for this ZIP: Santa Catalina and Catalina (both marked as not valid for mailing, but recognized). The official mailing name is Avalon. All addresses in 90704 should include a PO Box number. There's no city delivery indicator for this ZIP, which matches the island's PO Box-only reality.
Street names blend Spanish heritage (Camino del Monte, Calle del Sol), beach geography (Pebbly Beach, Descanso Beach), and historic island references (Wrigley Terrace, Banning).
ZIP Code 90704 has 3,715 residents and 1,493 households (average 2.45 persons per household). The median age is 40.3 years, slightly older than the state (37.5) and slightly older than the nation (38.8). The gender split is 49.0% male and 51.0% female, which is about the same as the state male share (49.4%), making this a female-majority area. Largest groups are Hispanic or Latino (52.9%) and White (50.5%, much higher than the state average of 41.2% and well below the national average of 61.6%); Hispanic or Latino residents make up 52.9%, which is much higher than the national average (18.7%), and Other / Two or More Races share is much higher than both the state (21.2%) and national averages (8.4%).
