Mail Classification Schedule (MCS)

The Mail Classification Schedule describes every product offered to the public by the US Postal Service and serves as a standard reference work when reviewing ongoing postal products.

The Mail Classification Schedule containing the market dominant product list, the competitive product list, and comprehensive product descriptions is currently under construction. It will be posted in this location following a formal rulemaking which will provide the opportunity for public comment.

A historical copy of the Domestic Mail Classification Schedule is available below. The Domestic Mail Classification Schedule is the predecessor to the Mail Classification Schedule. It governed rates and classifications of domestic postal products prior to enactment of the Postal Accountability and Enhancement Act (PAEA), Pub. L. 109-435, 120 Stat. 3198, December 20, 2006.
