What is USPS Regional Rate Shipping?

USPS Regional Rate is a cost-effective shipping service offered by the United States Postal Service. It's designed for small, dense packages that are typically more expensive to ship long distances.

USPS Regional Rate Boxes come in different sizes (Box A and Box B), but unlike USPS Flat Rate Boxes, the price for Regional Rate Boxes varies based on the distance between the origin and destination of the package (which is determined by USPS zones). Box A is designed for small, heavy items up to 15 lbs., whereas Box B is slightly larger and can hold up to 20 lbs.

The key advantage of Regional Rate Boxes is that they often provide a lower cost than other USPS services for relatively heavy packages that are small in size, especially for shorter distances. Unfortunately, USPS regional rate boxes have been discontinued and are no longer available effective January 22, 2023.
