Centerville's post office maintains 270 PO Boxes for just 96 local households. That's an adoption rate of 2.81, meaning nearly three times as many boxes as occupied homes. This isn't inefficiency. It's evidence that people from surrounding areas without carrier delivery travel here for mail service.
The ZIP serves 234 residents in a Classified as a PO Box zone where PO Box service is the only delivery option. There's no city carrier service, no rural routes. The post office manages one highway contract route (Route H) and a general delivery route (Route G). The street delivery infrastructure consists of a single named street: Senette Street, which has two delivery records but no secondary units like apartments.
The community sits in St. Mary Parish with a median age of 49.1 years. Census data shows 117 total housing units, with 96 occupied and 21 vacant. The median household income is $26,488, well below Louisiana's state median. Of the 234 residents, 85 identify as white, 24 as Hispanic or Latino, and the remaining population represents other racial groups.
This postal pattern reflects rural Louisiana's delivery reality. When street delivery doesn't reach your area, you drive to the nearest post office. Centerville's facility serves that function for a regional footprint that extends well beyond the 0.78 square miles of land within ZIP 70522. The 270 PO Boxes represent 34 businesses and hundreds of individual customers who depend on this location as their primary mail access point.
With only a single street appearing in USPS delivery records, Centerville's ZIP reflects a community where the post office itself—rather than street addresses—serves as the primary mail distribution point for a broad regional area.
ZIP Code 70522 has 234 residents and 96 households (average 2.44 persons per household). The median age is 49.1 years, significantly older than the state (38.1) and significantly older than the nation (38.8). The gender split is 43.2% male and 56.8% female, which is lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (52.6%, much lower than the national average of 61.6%) and Black or African American (36.3%, much higher than the national average of 12.4%); Hispanic or Latino residents make up 1.7%, which is much lower than the national average (18.7%), and Black or African American share is much higher than the national average (12.4%).
