The PO Box adoption rate of 1.25 means the facility maintains more boxes than there are occupied households in the immediate area. With only 8 households across the ZIP code's territory, the extra boxes serve surrounding properties that lack rural carrier delivery. FM Road 1601 and Interstate 20 define the main corridors here, connecting the post office to ranches and industrial sites that depend on this mail facility.
This is a PO Box-only zone. There's no street delivery option within 79776, making the post office the sole method for residents and businesses to receive mail. Four rural carrier routes extend from the facility, covering properties along FM 1601 and side roads branching into the surrounding rangeland. The ZIP code contains 18 ZIP+4 records, with 13 designated for PO Boxes and 5 for street addresses that receive rural route service.
The demographics show a median age of 50.3, with 100% of the small population identifying as Hispanic. All 21 housing units are spread across terrain where oil and gas operations shape the economy. Seven business establishments employ 102 workers, a ratio that indicates most people who work here commute from Odessa and other nearby cities. The post office at Penwell functions as a service point for an area where the working population vastly outnumbers the residential population.
Four distinct street names appear in postal records: FM Road 1601 (the main north-south artery), Avenue G, FM 1601 (alternate designation), and Interstate Highway 20. These aren't residential neighborhoods but reference points for delivery along rural routes that extend miles from the post office. The landscape here doesn't fit into city blocks. It's measured in sections and ranch roads, where distances between addresses can span several miles and a physical street presence doesn't guarantee street delivery exists.
Street names in 79776 aren't residential addresses but reference points along major transportation corridors. FM Road 1601 serves as the main north-south route, while Interstate 20 provides east-west access. Avenue G represents one of the few named local streets. These designations help rural carriers navigate an area where properties are identified more by ranch names and mileage markers than traditional street addresses.
ZIP Code 79776 has 3 residents and 8 households (average 0.38 persons per household).
