INFORMED DELIVERY® INTERACTIVE CAMPAIGN GUIDE
Appendix A – Mailer ID (MID) and IMb Information
The MID and the IMb on the mailpiece are the key to activating an Informed Delivery campaign.
• Grayscale scanned images are linked to Informed Delivery users based on the Delivery Point
Code (DPC) within the IMb. This is the 9-digit ZIP Code plus a 2-digit Delivery Point value.
o Only consumers/mail recipients that reside in a dwelling that has a unique 11-digit Delivery
Point Code can participate in Informed Delivery; this also applies to multi-unit dwellings.
• Campaign images and URLs (supplemental content) are linked to mailpieces based on the MID in
the barcode on the actual mailpiece.
o A MID provided in electronic postage statement documentation (eDoc) has no impact on
the Informed Delivery program. See Appendix C for PostalOne! RMR information.
