USPS Regional Rate Shipping | Overview

Regional Rate is a cost-saving USPS mail service that utilizes a shipment's distance to its destination. Regional Rate Boxes, which can be used domestically and internationally, provide a low-cost shipping alternative for commercial and online customers. To see the 2021 USPS Regional Rates view the article Priority Mail - USPS Commercial | Rate Table.

ShippingEasy does not support the use of Regional Rate boxes when shipping internationally.

Priority Mail International Regional Rate Box prices are available only to customers who have an agreement with the Postal Service using Permit Imprint or PC Postage. Contact USPS for more information.

As a little-known service of the USPS, Priority Mail Regional Rate gives big savings to businesses sending shipments weighing 20 lbs or less. The key to Regional Rate is utilizing the zones that determine the rates. Instead of charging one rate no matter the distance (like Priority Mail Flat Rate), Regional Rate offers rates that vary by “zone”.

When combined with a ShippingEasy account (which offers commercial discounts) Priority Mail Regional Rate is the ultimate savings secret weapon. 

Regional Rate Box Dimensions

There are two sizes for Regional Rate boxes:

Regional Rate
Box Type
Description Top Loading Side Loading Weight

Box A

Ships at approximately the same rate as a regular 2lb package 10" x 7" x 4-3/4" 12-13/16" x 10-15/16" x 2-3/8" Up to 15 lbs, same flat rate

Box B

Ships at approximately the same rate as a regular 4lb package 12" x 10-1/4" x 5" 15-7/8" x 14-3/8" x 2-7/8" Up to 20 lbs, same flat rate

Cost Advantages of Regional Rate Boxes

Here is a real-world example:

In 2021, if you ship a 10 lb package across the country from Austin, TX to Manhattan, NY (Zone 7) look at the savings:

  • Priority Mail custom (weight-based) box costs $33.63 (USPS - Commercial Pricing)
  • Priority Mail Medium Flat Rate Box costs $13.75 (USPS - Commercial Pricing)
  • Priority Mail Regional Rate Box A costs only $11.63 (USPS rate)

Now – if you ship this same 10 lb package closer to home from Austin, TX to Houston, TX (Zone 2) look at the savings:

  • Priority Mail custom (weight-based) box costs $10.15 (USPS - Commercial Pricing)
  • Priority Mail Medium Flat Rate Box costs $13.75 (USPS - Commercial Pricing)
  • Priority Mail Regional Rate Box A costs only $7.83 (USPS rate)
Priority Mail Regional Rates listed here are available through ShippingEasy as commercial discounts. If a Regional Rate shipping label is purchased directly from the US Post Office, retail rates and additional fees may apply.

Thats just dandy stating the prices and zones, but you are just expecting a lay person to know Where the zones are? This is not helpful at all. Debbie

Hello Debbie - Thanks for asking for clarification. Zones are a tool that the USPS uses extensively to track distances between shipment origins and destinations. We have an article dedicated to the subject, which includes some handy look up tools:

Within ShippingEasy, you'll also notice that we commonly call out the zone for a shipment. This information can be found on the Orders and Ready to Ship pages.

Hi Rodney - If you have a ShippingEasy account, you should be able to use these boxes to ship your PayPal orders. However, if you're not seeing the option, it's possible that you do not have an Endicia International & Expedited account connected with ShippingEasy. Learn how in this guide:

On the other hand, if you're shipping via PayPal, you would need to reach out to their support to verify what shipping services they provide access to. You could also consider opening a ShippingEasy account. Our plans start at free. Learn more about ShippingEasy at

Some good links...but when I went to "" it was not free.  It is a subscription service.  What did you mean by "Our plans start at free"?  There is a free trial if that is what you're referring too.  It looks like I can just use my Click-N-Ship account, but will still need to go to the post office for a Priority Mail Regional B Box.

Hi Frank - Thanks for asking for clarification!

ShippingEasy offers a free Starter plan. It still requires registering a ShippingEasy account, but there is zero monthly subscription fee. We have a page dedicated to the details of this plan, and you can also sign up for this plan here: Free Shipping Software

You're also welcome to read up on it in this guide: What is the FREE Starter plan and what is included?

Once you've signed up for ShippingEasy, the Endicia (USPS) carrier accounts are included at no additional cost. These allow you to access Commercial Base Pricing. Compared with the Retail rates available with Click'n'Ship, this can save quite a bit of money on postage. 

We have more information about how Click'n'Ship compares with ShippingEasy in this guide: Is there a good alternative to Click-N-Ship?

Priority Mail Regional Rate boxes can then be obtained from your local post office, or you can have them delivered to you for free. Find more information about ordering free USPS supplies in this guide: USPS Supplies: Ordering Details (FREE)

I hope this helps!

Hello Jennifer,

What is the best location to drop-off the boxes, for bulk shipping, say 20 boxes at a time?

Comment actions Permalink

Hello Chandana - Thanks for posting your question!

I recommend reaching out to your local Post Office, specifically the one that will be initially handing your packages. Each Post Office has slightly different preferences and policies, so they can provide you with the best advice for dropping off a large quantity of packages.

Anyone at the retail counter should be able to help. However, you may be interested in speaking with the Post Master if you plan to have a long term, higher volume, relationship with the branch.

If you do have many packages at once, you might also be interested in USPS SCAN forms and package pickup. We have more information about both of these in the following articles:

Your Post Office could also advice on their preferences for these services.

I just ordered the regional a boxes and waited weeks for them to be delivered to my house. I package one up and went to my local post office and mailed it to zone one. Instead of $6.52 they charge me $8.77. Why are the prices online different than what they are when you get to the post office? Again I was using a regional box say the box weighed 2 pounds 11.7 ounces and it was going from the ZIP Code 233222 ZIP Code 22903 which is zone one? My regional a box cost me more to ship today that it would’ve cost me if I mailed it regular priority mail. How was the saving people money instead of causing extreme frustration?

Hello Lynn, and thanks for posting to our support center.

The Regional rates listed on our page here, are the commercial discounted rates you would receive through a ShippingEasy account.

However, if you choose to ship with the US Post Office directly, unfortunately an additional fee will be added to the cost of shipping, depending on the zone your package is being shipped to.

I'm very sorry for any confusion our information caused you. We would also recommend checking with your local post office before making any purchases in the future to confirm the prices ahead of time.

Hi Mark,

Thank you for your message.

To get the rates you are referring to, you would need to sign up for a ShippingEasy account here:

Once the order is in the system and you click Create Shipment to send it to the Ready to Ship page, your Carrier, Service, and Packaging selections can be made in order to generate the label.  Here is an overview of what would show there:  Overview: READY TO SHIP page
