Also known as USPS BRM Horizontal Bars
This Barcode Symbology is supported by the following Neodynamic products: USPS Business Reply Mail (BRM) enables you to receive First-Class Mail back from customers while paying postage only on the pieces that your customers return. You may distribute cards, envelopes, self-mailers, and other types of mailpieces as BRM.
Six basic design elements are required on a BRM piece. One of these design elements is called Horizontal Bars. To help identify your mailpiece as BRM, you must print a series of horizontal bars below the "NO POSTAGE NECESSARY" endorsement on your BRM pieces. These bars must be uniform in length, thickness, and spacing. Each bar must be at least 1 inch long and 1/16 inch to 3/16 inch thick.
There must be at least a 1/2-inch clearance between the right edge of the ZIP Code in the delivery address and the left edge of the horizontal bars. The bottom bar in the series must be above (not on or below) the top of the delivery address line - the next-to-last line in the address, just above the line with the city, state, and ZIP Code
