The two most common USPS services a merchant uses to ship with are First Class and Priority Mail. Generally, the deciding factor in making a decision in First Class vs Priority Mail comes down to weight. If a parcel weighs less than 16 ounces, it makes the most sense to use First Class Mail. However, there are instances when the choice is not so black and white. For instance, the USPS has recently slowed First Class Mail. There are instances when one of these services will win over the other. We’ll go over a few situations where one service may win over the others.

What is USPS First Class Mail?

USPS First Class Mail is an economical way to ship parcels, thick envelopes, and envelopes weighing under 16 oz. The maximum allowable size for parcels are dimensions of 22″ x 18″ x 15″. Delivery usually takes 2–5 business days for parcels to reach their final destination. Letters are a little faster since they sort more quickly. 

Why is it Called First Class Mail? 

First Class Mail doesn’t mean the same as a first class flight. In the world of USPS, that would Priority Mail Express.

What is USPS Priority Mail?

USPS Priority Mail is the USPS’s class of mail that is their top priority to ship out. Priority Mail is a a service that lets you send parcels weighing less than 70 lbs domestically. The maximum dimensions are 108” in combined length and girth (the length of the longest side, plus the distance around the thickest part of the package). Generally, USPS Priority Mail takes 1-3 business days to reach its final destination.

Internationally, Priority Mail International gets another advantage since it typically cuts shipping time down significantly. Because of this, it is a little bit more expensive than First Class Mail.

Priority Mail is also closer to UPS and FedEx services. However, it is frequently more economical than both UPS or FedEx for packages weighing under about 10 lbs. This is generally because a USPS vehicle passes by addresses each day. Smaller parcels that can fit in a mailbox typically are economical. If the parcel’s size/weight requires the delivery driver to leave their vehicle and/or are too large to fit in their messenger bag, then the price can begin to rise quickly.
