Quick Summary

Second-class mail refers to a category of mail in the United States and Canada that primarily includes newspapers and magazines sent to regular subscribers. This class of mail is recognized for its preferential rates, as the dissemination of information through publications is considered to be in the public interest.12

The U.S. postal system has evolved significantly since its early days, with mail being formally divided into classes in 1863. Second-class mail, alongside first-class (letters), third-class (other printed matter and merchandise under one pound), and fourth-class (merchandise or printed matter weighing one pound or more), allows for varied rate structures based on content and handling costs.2
