New Regional USPS Flat Rate Priority Shipping: Low-Cost Solutions for Packages with a Short Trip

When you sell online, your shipping times are crucial. Priority Mail is a great option, but not always the most economical. Until now the Flat Rate boxes and envelopes have been limited in size and variety.

The USPS has issued four new flat rate box sizes (free from the USPS site) that are charged by distance (within limits, see rate chart below). There's no longer one rate for the entire country. You can pack as heavy a package as you wish, and still have it arrive quickly at your customer's door. There are also new free bubble padded 12 1/2" x 9 1/2" Flat Rate envelopes, as well as legal size.

You can only use these items if you are registered with the USPS as a Commercial Base Customer. This isn't as difficult as it sounds, not does it require you to ship many boxes every day. By using a service like Endicia (who has options for all the new boxes) you are automatically eleigible for these rates. (Here's a link to 60 days free Endicia service).

  • Regional Flat Rate Box A has a 15 pound weight limit
  • Regional Rate Box B has a 20 pound weight limit.

If the box exceeds the maximum weight for the box (either 15 lbs. or 20 lbs.), you will be charged the Priority Mail price, based on weight and zone.

There are two different shaped boxes, side loading and top loading for each of the two weighted categories. A total of four new boxes will be available.



Dimensions for Regional Rate Box A are as follows:

Side Loading – 13 1/16" x 11 1/16" x 2 ½"
Top Loading – 10 1/8" x 7 1/8" x 5"

Dimensions for Regional Rate Box B are as follows:

Side Loading – 16 1/4" x 14 1/2" x 3"
Top Loading – 12 1/4" x 10 1/2" x 5 1/2"
