Regional Rate Box A

There are two different Regional Rate A boxes:

A1  is the “lunchbox” size, and A2 is the flat side-loading box.

Both are similar in dimensions to the Priority Mail Flat Rate Medium Boxes.

A1 is 10 x 7 x 4.75, and Medium Flat Rate Box 1 is 11 x 8.5 x 5.5.  So A1 is slightly smaller.

A2 is 10 15/16 x 2 3/8 x 12 13/16, and Medium Flat Rate Box 2 is 11 7/8 x 3 3/8 x 13 5/8. Again, A1 is slightly smaller.

Regional Rate A costs around $7 to $10, and MFR costs $14.

Regional Rate A’s weight limit is 15 pounds, and MFR is 70 pounds.

Unless you ship heavy items, the Regional Rate boxes are better.
