Key Facts
  • This ZIP code serves at least 7 distinct communities including Ketchikan, Port Protection, Whale Pass, Naukati Bay, Kasaan, Edna Bay, and Port Prot (abbreviated).
  • Each remote community maintains its own PO Box range with a unique three-letter code (EDB, KXA, WWP, NKI, PPV), allowing residents to preserve local identity in mailing addresses.
  • The mail system combines 1 city carrier route and 1 rural carrier route, classified as mixed urban and rural delivery.
  • USPS records show zero population and zero area because this is a MultiPoint ZIP covering scattered island communities rather than a contiguous geographic area.
  • Twelve businesses employ 38 people within the ZIP's service area, reflecting small-scale commercial activity typical of remote Alaska settlements.
  • Only one actual street appears in the delivery records: W Davidson Ave, with the remaining 5 delivery points being PO Box ranges for outlying communities.

Delivery Structure

The delivery pattern combines city carrier routes (serving 5 ZIP+4 records) with a rural route (1 ZIP+4 record), reflecting the geographic challenge of mail delivery in this island region. Street delivery exists for W Davidson Ave in Ketchikan proper, while the surrounding communities maintain dedicated PO Box ranges: BOX EDB (Edna Bay), BOX KXA (Kasaan), BOX WWP (Whale Pass), BOX NKI (Naukati Bay), and BOX PPV (Port Protection). This structure lets residents in each settlement maintain a distinct mailing identity despite sharing a ZIP code.

Geographic Reality

The ZIP appears in USPS records with zero population and zero area, which doesn't reflect reality. This happens when a ZIP serves multiple geographic points that can't be aggregated into a single boundary. The spatial data confirms this is a MultiPoint geometry rather than a polygon. The parent ZIP 99901 (also Ketchikan) provides street delivery for the city's main residential and commercial areas.

Local Economy

Twelve businesses with 38 employees operate within this ZIP's coverage area. The mixed urban and rural delivery designation reflects the reality that some locations have structured addresses (like W Davidson Ave) while others depend entirely on PO Boxes. For residents in Port Protection, Whale Pass, and similar communities reachable only by boat or floatplane, the PO Box isn't just convenient—it's the only option.

Street Name Patterns

Island Communities Remote Settlements Box Range Codes

Only one traditional street (W Davidson Ave) appears, while five communities maintain dedicated PO Box ranges with three-letter codes that preserve local identity. This structure is typical of Alaska's island communities where addresses follow PO Box conventions rather than street-based systems.
