First-Class Package Service offers the best rates for lightweight shipments. Commercial service is provided for parcels up to 15.999 oz.
USPS accounts connected to ShipWorks currently allow a maximum value of 15.99oz. As long as the actual package weighs less than 15.999oz, the USPS will accept a shipment of 15.99oz as having accurate postage.
First-Class Package Service is not the same as First-Class Mail. One of the main advantages of First-Class Package Service is that it includes tracking or delivery confirmation.
Delivery estimated 1-5 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.
First-Class Package Service rates are based on parcel weights, zone, and rate class.
Costs increase as weight increases. In addition, costs 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).
Commercial pricing is a discounted postage rate, lower than Retail pricing. It is only available to qualifying shippers, including ShipWorks subscribers.
