Address an Envelope

Address the envelope parallel to the longest edge of the envelope. The city, state, and zip code should all be on the same line. Include your return address in the upper left-hand corner of the envelope. Place the stamp or postage in the upper right-hand corner. A 1-ounce envelope requires one First-Class stamp. Each additional ounce of weight is $0.29 more. See the Mail Services staff if you're unsure of how much postage your letter will need.
