Pedro Bay sits on the eastern shore of Lake Iliamna in southwestern Alaska, 230 square miles of remote territory accessible only by boat or small aircraft. The 43 residents are split almost evenly between Native Alaskan (21 people, 49%) and White (20 people, 47%) populations. With a median age of 42.2 years and all 24 households occupied year-round, this is a permanent community, not a seasonal camp.
This is a PO Box Only Zone. There's no alternative mail delivery across the territory. Despite covering 230 square miles, the community post office (facility code C, a Community Post Office) maintains just 2 PO Boxes. That's because most mail arrives via a single rural carrier route serving the handful of homes along Pedro Bay Road. The extremely low PO Box count (2 boxes for 24 households) shows that rural delivery handles most residential mail, with boxes reserved for seasonal use or specific needs.
The Iliamna mailing name works for this ZIP. Both Pedro Bay and Iliamna are accepted addresses. This reflects the broader Lake Iliamna region's interconnected communities. Median household income of $80,833 exceeds Alaska's average, supported by subsistence activities, government work (7 of the small workforce are in public administration or other services), and seasonal tourism tied to the lake's world-class sportfishing.
Nearly half the housing stock (30 of 65 units, 46%) sits vacant for seasonal use. These are fishing lodges, guide cabins, and summer homes serving Lake Iliamna's recreation economy. The 20 owner-occupied homes and 4 rentals house the year-round population. With only 1 street name in the ZIP+4 database and zero business establishments recorded, Pedro Bay operates at the edge of Alaska's formal addressing system.
Use either "Pedro Bay, AK 99647" or "Iliamna, AK 99647." Rural route delivery serves most homes. PO Boxes are available but not required for most residents.
Only one street name appears in the ZIP+4 database, reflecting minimal formal addressing in this remote lakeside community.
ZIP Code 99647 has 43 residents and 24 households (average 1.79 persons per household). The median age is 42.2 years, older than the state (35.6) and older than the nation (38.8). The gender split is 55.8% male and 44.2% female, which is higher than the national male share (49.1%), making this a male-majority area. Largest groups are American Indian & Alaska Native (48.8%, much higher than the state average of 15.2% and well above the national average of 1.1%) and White (46.5%, much lower than the state average of 59.4% and well below the national average of 61.6%); Hispanic or Latino residents make up 0.0%, which is much lower than the national average (18.7%), and American Indian & Alaska Native share is much higher than both the state (15.2%) and national averages (1.1%).
