Key Facts
  • The post office maintains 187 PO Boxes for just 50 local households, giving an adoption rate of 3.74 that indicates significant regional service beyond the immediate community.
  • Highway 1 dominates the delivery infrastructure with four carrier route records, making this a highway-oriented mail facility rather than a traditional town post office.
  • All 49 occupied housing units are owner-occupied, with zero households reporting mortgage costs exceeding 30% of income.
  • The community employs 229 people across just 14 business establishments, suggesting larger employers or operations concentrated in a small geographic area.
  • With a median age near 50 and a population of 104 spread across 61 total housing units, this represents a stable but aging rural community.
  • The ZIP covers only 0.516 square miles of land area, making it one of the smallest geographic PO Box ZIP codes while serving a disproportionately large customer base.

Regional Hub Along Highway 1

The ZIP covers just over half a square mile in Assumption Parish, but the mail operation tells a different story. Highway 1 dominates the delivery infrastructure with four carrier route records, while Myles Street and King Street account for the limited residential delivery. The post office maintains 32 business boxes alongside the residential service, supporting a small commercial presence that employs 229 people across 14 establishments.

Mixed Delivery System

This isn't a PO Box only community by necessity. Residents have access to rural and highway carrier routes, creating a mixed delivery system that serves both local addresses and the regional PO Box customer base. The facility code 'P' indicates the ZIP contains only PO Box addresses, but the presence of street delivery routes shows people aren't forced to use boxes. They choose them.

Community Demographics

The 2020 Census counted 81 white residents and 15 Black residents in a population that skews older, with a median age near 50. All 49 occupied housing units are owner-occupied, and zero households have mortgage costs exceeding 30% of income. The stability shows in the numbers: no one works from home, everyone commutes, and the community has maintained its character as a highway corridor settlement serving the broader Assumption Parish region.

Street Name Patterns

Highway Dominant Minimal Grid Corridor Settlement

Highway 1 defines this community's mail infrastructure, with minimal residential street development on Myles and King streets. The highway-dominant pattern is typical of Louisiana corridor settlements that grew along major north-south routes rather than developing traditional town grids.
