Midfield is a small unincorporated community in Matagorda County, Texas, about 80 miles southwest of Houston. This is a PO Box Only Zone, meaning there's no alternative mail delivery for residents. The post office with its 140 PO Boxes is the only way to receive mail in this 14-square-mile area.
With 397 residents and 120 occupied households, Midfield has a PO Box adoption rate of 117%. That's more boxes than households because the post office also serves surrounding rural areas. Two rural carrier routes extend from here, delivering to addresses along County Roads 449, 482, 485, and 101, plus State Highway 111 and FM roads 458 and 2431.
The community has a rural character with roots going back generations. Of the 138 housing units, 42 are mobile homes (30%). Another 42 units date to before 1939, showing the area's long settlement history. Families here tend to be larger than average, with 3.3 people per household compared to the national average of 2.5. Median age is 34.9 years, suggesting working-age families rather than retirees.
Residents picking up mail can only use a PO Box address. The format is: Name, PO Box [number], Midfield, TX 77458. Street addresses exist for rural delivery points, but anyone in the core community needs a box at the Midfield post office.
Street names reflect rural Texas road infrastructure: county roads, state highways, and FM (farm-to-market) routes.
