Enhance your direct marketing with USPS postal carrier boundaries

Carrier Routes depict the areas served by USPS mail carriers and include both residential and business routes, making them an excellent resource for direct marketers. To provide greater accuracy and visual appeal, the boundaries follow roads.

Each feature of the carrier route has its own unique record, regardless of the number of polygons that compose it. In the case of ‘’split routes,’’ the centroid file will use the carrier route’s gravity center point, which ensures that the centroid will be in one of the polygons of the carrier route. These “split routes” will always contain all the information needed to draw each polygon.
