Priority Mail is a versatile, efficient, and affordable service. Delivery estimated between 1-3 days.
This is a domestic service. Domestic mail is transported:
within, across, and between the United States.
from the united States to
U.S. territories, Marshall Islands, Federal States of Micronesia.
U.S. military and diplomatic posts, and the United Nations, NY.
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 increases.
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).
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.
Retail pricing is offered directly from the USPS at Post Office retail locations or USPS.com. It does not include discounts on postage prices like those received via .
