ZIP Code 99613 in King Salmon, AK

Geographic Significance

King Salmon sits on the banks of the Naknek River in southwestern Alaska, serving as the primary gateway to Katmai National Park and Preserve. This small community of 375 residents manages infrastructure for thousands of seasonal visitors who come to see brown bears fishing for salmon at Brooks Falls. The town's location, 236 square miles of Bristol Bay territory, positions it as a critical access point for both Katmai and the surrounding Alaska Peninsula.

A PO Box Only Zone

This is a PO Box Only Zone. There's no alternative mail delivery across this vast territory. The King Salmon post office maintains 249 PO Boxes for 158 local households, a 1.58 adoption rate that shows the facility serves beyond the immediate community. Mail also goes to Igiugig, a smaller village recognized as a valid mailing alias for this ZIP code. Rural carrier routes (R001 and R002) handle limited delivery, but PO Boxes remain the primary method.

Street Names Tell the Story

Street names tell the story of this fishing and aviation hub. Roads bear the names of salmon species: Sockeye, Coho, Humpy, Char, and Quinnat. Wildlife roads include Bear Trail, Caribou, Beluga, and Ptarmigan P Trail. Federal presence is obvious in National Park Service Road, FAA Road, Weather Service Access Road, and Airforce Road. Local character shines through in quirky names like Flat Nose Henry Street, Cuckoo Harry Lane, and Plane Crazy Road.

Government Employment Dominates

The community's economy runs on government work. Of the employed residents, 138 work in public administration (72% of the 192-person workforce). That includes National Park Service staff, FAA personnel, weather service employees, and Alaska Department of Fish and Game workers (F and G Access Road). Another 92 work in transportation, warehousing, and utilities, supporting the regional airport that connects Bristol Bay communities to Anchorage. Just 52 work in education and health care services.

Demographics

King Salmon's population is 53% White (197 residents), 27% Native American (101 residents), and 19% identifying as two or more races (70 residents). The median age of 34.7 years is younger than most Alaska communities, likely due to seasonal workers and young families employed in government and tourism support roles. Median household income is $121,786, well above the national average and typical of Alaska's federal employment wage premiums.

Seasonal Housing Patterns

Housing patterns show the seasonal rhythm. Of 327 total housing units, only 158 are occupied year-round. That's 169 vacant units, with 111 classified as seasonal, recreational, or occasional use (34% of all housing). During summer months when Katmai visitors peak, the population swells with seasonal workers, fishing guides, and lodge staff. Median home value is $318,400. Split is nearly even between owners (80 units) and renters (78 units).

The Airport Connection

The airport is central to daily life. Everything arrives by air. Groceries, mail, building supplies, and people all come through King Salmon Airport. No roads connect to Anchorage or other major cities. That isolation makes the post office a critical node in the community's connection to the outside world.
