Mail Classification Schedule (MCS)

Current MCS (redline version)

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. A draft working copy of the Mail Classification Schedule is available here. It is typically updated on a weekly basis in redline legislative format to represent the most current US Postal Service product offerings.

On an annual basis, the Mail Classification Schedule in redline legislative format is retired to the archive appearing here. All redline legislative changes are incorporated into a new baseline Mail Classification Schedule and posted in this section for legislative markup in the following year. The information provided therein is obsolete and is provided for reference only.
