All about Priority Mail Regional Rate [Updated with 2018 Rates]

Priority Mail Regional Rate boxes

Is USPS Priority Mail® a part of your e-commerce shipping strategy? With delivery to most domestic locations in just one to three days, Priority Mail is often the most affordable shipping option and also includes free USPS Tracking®, free Package Pickup, free USPS shipping supplies and up to $50 of insurance with most shipments.

If your e-commerce business ships small, dense packages over short distances, then you could save even more on shipping by using Priority Mail Regional Rate, both over private shipping carriers AND other USPS services.

Priority Mail Regional Rate postage pricing is based on box size and its destination. For instance, a shipment that’s going across town will cost significantly less than a shipment going across the country.

Priority Mail Regional Rate boxes come in four pre-defined sizes so shippers can select the size and shape that best suits their needs (click image to enlarge):

Regional Rate vs. Other Priority Mail Options

Wondering when you should use Priority Mail Regional Rate instead of Priority Mail Zone-based pricing or Priority Mail Flat Rate? To find out which option is right for your shipment, you’ll want to compare your box size and destination. For example, using Priority Mail Regional Rate Box A is cheaper, across all Zones, for packages weighing 3 pounds or more, but if your package weighs less you’re better using the Priority Mail Zone-based service. We’ve put together a comprehensive blog post to help you understand all Priority Mail options, including Regional Rate—find it here.

Regional Rate vs. Private Carriers

Priority Mail Regional Rate comes without the surcharges private carriers attach for services like residential delivery and fuel. As previously mentioned, you get the most savings out of Priority Mail Regional Rate when shipping short distances. But just because the name indicates a more local service, there’s still a potential for savings, no matter the Zone. Here you can see the cost savings per package when using Priority Mail Regional Rate Box A instead of UPS Ground—note that cost savings were found for Regional Rate packages up to 15 pounds going both short distances AND to nationwide destinations (click on image to enlarge):
