What is First Class Package Service?

Created:   |   Updated:

First-Class Package Service offers the best rates for shipments weighing equal or less than 15.9 oz.

An envelope is too small, a standard box is too big - sounds like a scene right out of Goldilocks and the Three Bears - you need something just right! If your shipment is less than a pound and is being shipped in a custom box or envelope, First-Class Mail is the most affordable option for you. In most cases, delivery will be within three days.
