The EDDM Format: How to Create a USPS-Compliant Campaign

Published by on November 15, 2021

Every Door Direct Mail® is a USPS®-based direct mail service that caters to small businesses across the country.

Any USPS-authorized business needs to follow the EDDM format when it comes to creating a mailing campaign.

EDDM format

Let’s discuss these EDDM requirements in detail.

What is EDDM Format?

Only Marketing Mail Flats based on the USPS® guidelines are eligible to be mailed with EDDM®.

These include booklets, brochures/leaflets, postcards, newsletters, large envelopes, magazines, etc. Your mailer must meet the required EDDM criteria such as height, weight, thickness, and size.

Weight and thickness

  • 0.007” thick
  • 3.3 ounces or less in weight

Shape and size

  • Square or rectangular mailers
  • Four square corners or curved corners within a radius of 0.125”

EDDM Indicia

  • Larger in size than 0.5”x0.5”
  • The postal address must be “ECRWSS” below the permit or within the indicia. It is an abbreviation for ‘Extended Carrier Route Walking Sequence Saturation’
  • The font must be in 4-point size and in all caps
  • A space of 0.125” should separate the Indicia from the top and right edges
  • The Indicia must be in the upper right-hand corner of the mailer, within 1.625 inches from the right edge, and 1.375 inches from the top edge

Minimum quantity and delivery rules

  • 200 mailers per ZIP code, unless the mail routes contain less than 200 addresses
  • Every dwelling unit in the chosen route will receive the mailer
  • Business units and P.O. boxes can be exempted from receiving the postcards
