Twain sits in the mountains of Plumas County, California, where 139 people occupy just 60 of the area's 120 housing units. The remaining 44 units (37% of total) sit vacant for part of the year, typical of communities where second homes or seasonal retreats dominate. With a median home value of $427,500 and a median age of 47.9, this isn't a retirement community but rather a quiet mountain enclave where property owners maintain year-round addresses even when they're not present.
The post office at Twain maintains 37 PO Boxes for the area's 60 occupied households. That 0.62 adoption rate reflects a mix of local residents who use street delivery along Twain Road and seasonal property owners who need a permanent mailing address regardless of when they visit. The ZIP's classification as PO Box-only doesn't mean everyone must use boxes; it means the 95984 ZIP itself contains only PO Box delivery records, though street delivery does exist in the community.
Only three business establishments operate here, employing just three people total. This is private land, not resort infrastructure. The community covers 36.6 square miles of mountainous terrain at coordinates 40.03°N, 121.12°W, with minimal commercial activity. Virgilia appears as an alternate name for the area, though Twain is the official postal designation. The area's single named building in postal records is simply "POSTMASTER," and Twain Road is the only street with its own ZIP+4 carrier route.
With only Twain Road appearing in postal delivery records, this community's development is minimal and centered along a single access route through mountain terrain. The singular street presence reflects the area's sparse development pattern typical of mountain residential enclaves.
ZIP Code 95984 has 139 residents and 60 households (average 2.32 persons per household).
