Nail the Address Block — Avoid the Reprint
A quick guide for designers who want their mail to fly through USPS automation without delays or extra postage.
Designers: This Is Where It Gets Technical (But We’ll Make It Easy)
If you’re working on a direct mail project — postcard, letter, or self-mailer — and aiming for USPS presort automation discounts, **getting the address block right is critical**. Misplace it, and you’re risking delays, extra postage, or worse — a reprint.
Here’s the short version: USPS has strict requirements for where and how your address block should appear on Standard Letter mail. The image below lays out the required zone — and yes, we've designed hundreds of pieces using this exact format. Trust us, it matters.
Pro Tip: The return address isn’t shown in the image, but it's still required. Our print services team will make sure everything lines up beautifully.
