Cornerstone Services helps your organization apply for non-profit mailing privileges, maintain compliance, and execute cost-effective direct mail campaigns that stretch your budget further.

We've guided dozens of Hudson Valley non-profits, churches, civic organizations, and charitable foundations through the USPS authorization process. From preparing PS Form 3624 to designing mail pieces that meet postal automation requirements, we handle the details so you can focus on your mission.

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.

USPS typically processes non-profit authorization requests within 30–60 days. We recommend applying well in advance of your first planned mailing.
