USPS Mail Services

The USPS uses a vast network of Post Offices, Processing and Distribution Centers, Priority Mail Processing Centers, Air Mail Centers, and Bulk Mail Centers to sort, process, distribute, and deliver mail. Riva Post Offices serve as one of the primary points of customer contact in the mail delivery process.

Riva Mail Delivery Services

Post Offices in Riva accept mail and packages from senders, offering a range of mailing and pricing options. The most common form of mail delivery, and one for which the Riva USPS has a legal monopoly, is residential first-class mail. 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. Riva 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 Anne Arundel County Post Offices.

Riva PO Boxes

Businesses and residential customers can also use the Post Office to receive their mail instead of choosing delivery to their door. Post Office Boxes, also called P.O. Boxes, are available for rent in multiple sizes for a monthly rental fee.
