Note: As of October 19, 2022, ShippingEasy now offers the lowest USPSⓇ shipping rates in the industry, and the rates reflected in this blog are prior to this change and may not be accurate. For more information on these new rates, check out our blog!

Similar to USPS Priority Flat Rate®, the shipping cost of Priority Mail® Regional Rate boxes are based on specific criteria instead of varying based on your package’s dimensions. USPS flat rate boxes cost the same regardless of destination, the rate you pay for Regional Rate boxes varies based on how far you are sending them (e.g. what zone or “region”). USPS currently offers two types of Priority Mail® Regional Rate boxes:

USPS Regional Rate Box A: Shipments of up to 15 lbs.
USPS Regional Rate Box B: Shipments of up to 20 lbs.

One thing to note is that Regional Rates are strictly an online service, so you can’t get the boxes at your local post office. If you buy the postage for them at the post office, they’ll add a fee to the overall price. You can find savings by using Regional Rate boxes for your orders, especially with Commercial USPS rates with ShippingEasy.

Your shipping software can tell you when to use Regional Rate and when to use Flat Rate. Try ShippingEasy free for 30 days!

For example, if you ship a 10 lb. package across the country from Houston, TX to New York, NY, your shipping cost would be:

Priority Mail® Medium Flat Rate Box costs $14.25 (ShippingEasy rate)
Priority Mail® costs $24.52 (ShippingEasy rate)
Priority Mail® Regional Rate Box A costs only $11.55 (ShippingEasy rate)

Priority Mail® Medium Flat Rate Box costs $14.25 (ShippingEasy rate)
Priority Mail® costs $10.29 (ShippingEasy rate)
Priority Mail® Regional Rate Box A costs only $8.38 (ShippingEasy rate)
