Regional Rate Boxes

Effective January 22, 2023, Regional Rate Box pricing has been discontinued. Remaining Regional Rate Boxes can still be used for shipping, but they will be treated as weight and rate packages. Customers who currently use these boxes are encouraged to place orders before supplies are depleted.

The recommended alternative for Regional Rate Box pricing is Priority Mail^™ Cubic. Priority Mail Cubic is a sub-service of Priority Mail in which commercial customers ship items using their own packaging and the pricing is based on the outer dimensions of the package rather than weight. In addition:

• This option offers similar cost savings as Regional Rate boxes.
• Priority Mail Cubic packages must measure 0.5 cubic feet or less, weigh 20 pounds or less, and the longest dimension may not exceed 18 inches.
• Priority Mail Cubic has zone pricing with five price tiers up to 0.5 cubic feet
