How EDDM works, in four steps
- Choose your routes. On the USPS EDDM map, pick carrier routes by ZIP code. Each route shows its household count, and you can filter by age, income and household size.
- Choose an EDDM-size piece. The piece must qualify as a USPS "flat": longer than 10.5″, or taller than 6.125″, or thicker than 0.25″, and no bigger than 15″ × 12″.
- Print and bundle. Pieces are bundled in stacks of 50 to 100 with a facing slip on top. Our packages offer shrink-wrapping in bundles of 100.
- Drop off and pay postage. With EDDM Retail you take the bundles to the post office that serves those routes and pay postage per piece at the current USPS EDDM rate. Up to 5,000 pieces per ZIP code per day.
Which sizes qualify for EDDM?
These are the postcard sizes we print that meet the USPS flat requirement. A 4″ × 6″ or 5.5″ × 8.5″ postcard is not EDDM-eligible, a common and costly mistake.
