So, you’re shipping a package and need to know which service to use. With the USPS, you have two main options to choose from—Priority Mail and First Class Mail. Let’s compare them and see how they stack up against each other. Making sure you use the best service for each of your parcels is a quick and easy way to save time and money when shipping.

Why is it called First Class Mail?

First Class Mail may sound like it’s the cream of the crop, and to a certain extent, it is. But this is not in comparison to Priority Mail. First Class Mail is a class of mail used to ship letters, thick envelopes, padded envelopes, and lightweight packages. First Class Mail is considered the top tier of mail in comparison to:

  • Second Class Mail: periodicals, magazines, newspapers that are printed more than 4 times a year.
  • Third Class Mail: Marketing mail, flyers, mailers, etc.
  • Fourth Class Mail: Media Mail (CDs, vinyl records, DVDs, books, bound print media consisting of 8 or more pages.)

Shipping T-Shirts

Shirts, especially t-shirts are a good candidate to ship with First Class Mail. They’re light-weight and durable. Try using a poly mailers to cut down additional costs.

Why is it called Priority Mail?

Priority Mail is the USPS’s class of mail that is their top priority to ship out. It delivers parcels at a quicker speed than First Class Mail and allows for far heavier parcels (up to 70 lbs). Internationally, it is advantageous 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 require 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.

Shipping Shoes

Shoes are almost always going to ship using Priority Mail (Unless they weigh less than 16 oz). Check to see if Flat Rate options offer discounts over standard Priority Mail packaging.

Max Dimensions and Weight

USPS First Class Mail is typically used for smaller, lighter parcels with items whose insured value is not very high. Items over a pound and/or items of higher value work better with Priority Mail.

Max Default Insurance Coverage

A major advantage of USPS Priority Mail is that it includes coverage in the event that a parcel becomes lost or damaged in transit. First Class Mail offers no default coverage, however, both Priority Mail and First Class Mail do allow additional coverage to be purchased through the USPS or through a third-party provider such as Shipsurance.

Shipping Watches and Other Jewelry

While a watch almost always weighs under 1 lb and can be shipped with First Class Mail, Priority Mail offers up to $100 of coverage in the event that the parcel is lost or damaged.

Price Comparison

First Class Mail is a more economical shipping option than Priority Mail. When the parcel is available to ship with either First Class or Priority, Priority Mail is usually about $3.00 more per parcel.
