Montgomery County Mail Delivery Services

First-class mail is designed for envelopes and lightweight packages, and it provides delivery to any location in the U.S. at a flat rate of one first-class mail stamp. Multiple other mailing options are available for letters and packages of any size. Priority mail options provide faster delivery at a higher cost than first-class mail. Montgomery County Post Offices sell stamps, shipping supplies, and certain collectors' and gift items. Customers can also choose Registered, Certified, and Return Receipt mail for varying degrees of verification of an item's delivery. Post Offices also sell money orders. Shipping and customs forms are also available at Montgomery County Post Offices.
