What are Business Reply envelopes/postcards/labels and Courtesy Reply envelopes/postcards?
Business Reply envelopes, postcards or labels are pre-addressed, specially formatted, usually barcoded envelopes, postcards or labels that enable a business to pay the postage for mail received from its customers. The USPS refers to a Business Reply envelope or postcard as a (BRM) Business Reply Mailpiece. A Courtesy Reply envelope/postcard (CRM) is similar to a Business Reply Mailpiece in that it is also a pre-addressed, specially formatted, barcoded envelope or postcard that a business provides to its customers as a convenience. Unlike a Business Reply Mailpiece, however, a Courtesy Reply Mailpiece requires postage at the time it is mailed.
