FAQ I want to print my labels from Microsoft Word...what data do I need to get a barcode? These are the 3 fields you need to have MAILERS+4 provide the data for: ZIP Code - 5 characters Plus 4 - 4 characters Delivery Point Code (DPBC) - 3 characters Microsoft Word is not Delivery Point Certified with the USPS, so to be sure to use the DPBC MAILERS+4 provides.
