Business Reply Mail enables the mailer to receive first-class mail from respondents by paying postage only on the mail that is returned. All business reply postage and handling charges are billed back to using departments. When you decide to design any business reply envelope or card, please call or email Mail Services Supervisor, 515-9858, for proper format. Your department FAS number must appear in the top left corner of the mail piece. To assist departments with formatting business reply letters, cards, and labels, a sample of each category is provided. Please note the addition of a two(2) ounce BRM letter that has the ZIP + 4 code previously used for flat mail and parcels. The USPS has issued a new ZIP + 4 code for the University flat mail, parcels and all other non-letter mail. All BRM stock with an incorrect format should be disposed of as soon as possible. See Exhibit Business Reply Mail.
