Priority Mail is a versatile, efficient, and affordable service. Delivery estimated between 1-3 days. [Learn more about USPS Priority Mail].
Priority Mail rates are based on parcel weight, dimensions or packaging, and distance, as well as rate class.
When a custom package is used, parcel weight and dimensions are used to determine postage costs. Costs increase as weight and dimensions increase. [Learn how dimensions affect rates].
Postage costs also increase as the distance increases. USPS uses Zones to measure the distance a domestic shipment must travel, ranging from Zone 1 (local) to Zone 9 (very far away). Print a zone chart based on your zip code here.
In contrast, Flat Rate services require specially marked boxes and envelopes that receive one rate, regardless of distance or weight. In most cases, Flat Rate packages are the lowest cost option, if items fit within the box. USPS provides packaging at no cost. [Learn how to order USPS supplies].
On the other hand, Regional Rate service is a combination of ‘flat-rate’ with Zones. It requires using specially marked boxes. It can be a very cost-effective method if items fit within the box. [Learn more about Regional Rate shipping].
Commercial Pricing is a discounted postage rate, lower than Retail pricing. It is only available to qualifying shippers, including ShippingEasy subscribers. [Learn more about USPS Commercial Pricing].
