CMS has been designated vital by state agencies for them to successfully meet their operational missions. We take our role of processing and delivering the state’s mail very seriously. Our core and only function is to streamline government mailing and allow state employees to focus on their agencies’ priorities. This goal is pursued by offering a complete assortment of cost-saving mailing options and fulfilling our role as mail experts for the state of Washington.

United States Postal Service (USPS) Inspectors occasionally examine the states’ mail to protect against violations of the Private Express Statutes. These regulations reserve the exclusive right of the USPS to carry letters for compensation to ensure that sufficient revenue is generated to serve all areas of the nation at uniform rates. See Private Express Statutes for more information.
