If you are required by law to include certain non-address related information on the outside of an envelope, it must be placed outside the Optical Character Read area to avoid interfering with the readability of the delivery address and/or barcode. If voter information must appear in the delivery address block area (i.e., if address labels are used for both the voter information and the delivery address), then the voter information line must appear above the recipient line of the delivery address.
A Postal Service Mailpiece Design Analyst (MDA) can help you, at no charge, with this and other aspects of proper mailpiece design. For help with mailpiece design, connect with an MDA between 7:00AM – 7:00PM Central Time by emailing MDA@usps.gov or calling toll-free at 1-877-672-0007 (select option 2 for mailing and shipping, then option 2 for MDA). Also, mailpiece design information is available on PostalPro at https://postalpro.usps.com/mailing/mailpiece-design-analyst-mda-customer-service-help-desk.
