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.

Shipping and customs forms are also available at Frederick County Post Offices.
