It is extremely important to know what the post office addressing requirements are. If you design your mailer without considering the USPS requirements, you could end up paying more postage. Here are some of the general standards the post office has setup.

The addressing standards can be broken up into 2 categories, letters and flats:

For letters:

  • The address must be no more than 4 inches from the bottom
  • The address must be at least a 1/2 inch from the right or left edge
  • The address must be at least 5/8 from the bottom
  • Create a 4 x 2 area for the address block that falls within the above requirements to allow for the barcode as well as the address
  • The return address should not fall within the addressing area or you run the risk of your mailing getting delivered to you instead of the recipient

For Flats:

  • The delivery address in the upper portion, see pictures below
  • You may place the address parallel or perpendicular to the top edge, but not upside down in relation to the top edge
  • The USPS standards define the “upper portion” as the top half of a mail piece, but also maintaining a minimum 1/8-inch clearance from the edge

Here are some examples:
