The town itself occupies barely two hundredths of a square mile along S Main St. There's one street route serving local addresses, but the overwhelming majority of mail moves through the PO Box system. This isn't unusual for rural Indiana. Many small communities became postal hubs when surrounding areas never received carrier delivery infrastructure. The pattern continues today.
Carrier delivery at the Blanford post office includes three city routes and one general delivery route. Despite this infrastructure, the ratio of boxes to households shows most customers prefer or require PO Box service. The facility processes mail for named locations including the Postmaster office and Supervisor Accountable Paper building, both part of postal operations.
Vermillion County's rural character shapes mail delivery patterns throughout the region. Blanford sits roughly eight miles from Sandford and similar distances from several unincorporated communities. The median age of 38.9 years reflects a stable, working-age population rather than retirement or college demographics. With only two businesses registered in the ZIP code, this is residential and agricultural territory where the post office functions as a shared community anchor for scattered households across a wide service area.
Blanford has just one street with carrier delivery: S Main St running through the center of town. With only three delivery records on file, the street infrastructure reflects the community's tiny geographic footprint. The simplicity of the street system contrasts sharply with the complex regional service the post office provides through its extensive PO Box network.
