How Nonprofit Postage Rates Work

USPS nonprofit Marketing Mail rates are roughly 40% less than standard Marketing Mail. Qualifying for those rates requires a nonprofit mailing permit, which means filing PS Form 3624 with your local post office and providing proof of 501(c)(3) status. We walk nonprofits through that process and have been doing it since 1998. Once your permit is active, we design and print your fundraising appeals, donor acknowledgments, newsletters, and event invitations, then presort and mail them at the nonprofit rate.

The savings add up fast on high-volume campaigns. We handle the permit application and every mailing after that — in-house design, print, and mail for Hudson Valley nonprofits, churches, civic organizations, and charitable foundations.

PS Form 3624 Application

To mail at non-profit rates, your organization must submit USPS PS Form 3624 (Application to Mail at Nonprofit USPS Marketing Mail Prices) at the post office where you hold your mailing permit. The application requires documentation of your non-profit status, including articles of incorporation, IRS determination letters, and organizational bylaws.

Cornerstone Services provides a free interactive tool that walks you through the entire PS Form 3624 process step by step, collecting the information you need and helping you prepare a complete application package.
