NextDayFlyers is honored to work with nonprofit organizations to help them meet their goals. All we require is for nonprofits to fill out the 3623 form provided by the United States Postal Service (USPS).
The form helps USPS determine if your organization is authorized to send mail at special prices set by the USPS. The form will ask you for details like your national Nonprofit USPS Marketing Mail authorization number. Authorized organizations must display this number when asked to do so
Any organization can apply for the special rates as long as they meet the specific eligibility rules that apply to nonprofit USPS marketing mail. For more information, please visit the USPS website.
You can download the form here. Below is a screenshot of the form for reference:
