Nonprofit Postage: Who Qualifies, What You Save, and How to Get Set Up
Summary
Best for: Organizations whose main purpose fits one of the USPS’s eligible categories. Fastest win: Gather your IRS letter, organizing documents, and recent examples of your work before applying. Simple rule: Get USPS approval first, and use nonprofit postage only for eligible mail that belongs to your organization.
Nonprofit postage can help eligible organizations spend less when they mail postcards, letters, or other approved materials. But being a nonprofit, or having tax-exempt status, does not automatically qualify you. The United States Postal Service (USPS) must approve your organization, and each mailing must follow its rules.
This guide explains the process in everyday terms: who may qualify, what savings can look like, which paperwork to gather, and how to plan a useful nonprofit mailing.
What nonprofit postage is, and what it is not
Nonprofit postage is a lower price tier for eligible organizations mailing certain materials through USPS Marketing Mail. USPS Marketing Mail is commonly used for planned outreach, newsletters, invitations, and fundraising appeals. It generally costs less than First-Class Mail, but delivery is not as fast or predictable.
The nonprofit price applies to eligible USPS Marketing Mail, not First-Class Mail. Nonprofit mail also does not receive the same automatic forwarding or return handling people may expect from First-Class Mail. If an address has changed or a piece cannot be delivered, handling depends on the mail’s preparation and any services or endorsements used. Plan for different delivery timing and address outcomes.
For example, an eligible organization mailing 2,000 pieces could save hundreds of dollars in postage compared with the corresponding commercial USPS Marketing Mail rate. The exact difference depends on the mailpiece, sorting, and preparation. Printing and mailing-service costs are separate.
USPS rules cover both the organization’s eligibility and the content of each mailing. An approved organization cannot use its authorization to mail material for an unrelated organization or for-profit business.
Who may qualify for nonprofit postage?
USPS reviews an organization’s primary purpose. The main reason it exists and what it actually does. Its rules list eight eligible nonprofit categories. Examples below are starting points, not automatic approvals.
- Religious: A congregation or faith organization whose main purpose is worship or religious teaching.
- Educational: A qualifying school, museum, or organization that teaches or trains people.
- Scientific: A nonprofit whose main purpose is scientific research or sharing scientific information.
- Philanthropic (charitable): A food bank or foundation organized to benefit the public, such as by helping people in need.
- Agricultural: A farm bureau or similar group primarily supporting agriculture and agricultural education.
- Labor: A labor union or employee organization primarily working to improve workers’ conditions.
- Veterans: A veterans’ post or qualifying auxiliary, society, trust, or foundation.
- Fraternal: A qualifying lodge or chapter organization built around fellowship and mutual support among members.
The organization must be organized and operated for an eligible primary purpose. In plain terms, its founding documents and its real activities need to support the same qualifying purpose. USPS also requires that the organization not be set up for profit and that no net income benefit a private individual or stockholder.
Some organizations may have an IRS tax-exempt classification that commonly corresponds with an eligible category: for example, 501(c)(3) for religious, educational, scientific, or charitable organizations; 501(c)(5) for agricultural or labor organizations; 501(c)(8) for fraternal organizations; and 501(c)(19) for veterans’ organizations. These classifications can be evidence, but USPS makes its own eligibility decision. Not every tax-exempt group qualifies, and public schools or PTAs should check how their specific organization is structured and operated.
See the USPS eligibility rules in Domestic Mail Manual 703 and Publication 417 for category definitions and examples.
How much can you save?
The table below shows 2026 reference rates for automation letters weighing 3.5 ounces or less, without a destination-entry discount. It is included to show how nonprofit pricing compares with commercial pricing at each presort level.
Important: these are letter rates. Postcards are not priced as letters. USPS prices postcards under different Marketing Mail rate cells based on the piece’s size, weight, and preparation, and the percentage savings can differ from the figures below. Treat this table as an illustration of how the nonprofit tier works, not as a quote for a postcard campaign. Ask us (or check USPS Notice 123) for the rate that applies to your exact mailpiece before you budget.
| Presort level | Nonprofit rate | Commercial rate | Approx. postage savings |
|---|---|---|---|
| 5-Digit Automation | $0.185 | $0.395 | 53% |
| 3-Digit/SCF Automation | $0.225 | $0.435 | 48% |
| Mixed Automation | $0.257 | $0.467 | 45% |
| Carrier Route Saturation | $0.160 | $0.255 | 37% |
Presort means sorting the mail by ZIP Code or delivery route before it reaches USPS. A 5-Digit sort groups pieces going to the same five-digit ZIP Code. Mixed mail is spread across more ZIP Codes. Carrier Route Saturation pricing has its own route-coverage and preparation requirements. A mailing service can help organize the pieces and confirm which price, if any, your format and quantity meet.
As a simple illustration using the letter rates above, a qualifying 2,000-piece mailing at the 5-Digit level would have a postage difference of about $420: 2,000 multiplied by the $0.210 difference per piece. That is a postage comparison only; it excludes printing, preparation, and mailing-service costs.
These figures are from the USPS Notice 123 price list effective October 4, 2026. Postal prices change, and actual rates depend on the mailpiece, quantity, preparation, and entry options. Confirm current rates before you set a campaign budget.
Forms and paperwork: what to prepare
The main nonprofit eligibility application is PS Form 3624, “Application to Mail at Nonprofit USPS Marketing Mail Prices.” A responsible official of the organization, not its printer or mailing agent, must complete and sign it. The current PS Form 3624 and instructions explain the required fields.
In plain language, the form asks for:
- Organization details: Its full legal name, physical address, and alternate mailing address, if needed.
- Applicant details: The name and contact information of an official responsible for the application.
- Organization type: One category that best describes the organization’s primary purpose.
- Financial and tax information: Whether it is for-profit or provides private benefit, and whether it has federal tax-exempt status.
- Authorization history: Whether it has mailed at nonprofit prices before, or has had authorization denied or revoked.
- Mailing office and signature: The Post Office location requested and the responsible official’s signature, title, and date.
Gather supporting documents before you begin:
- Proof of nonprofit status: Often an IRS determination letter. If there is no IRS letter, USPS instructions allow a complete financial statement from an independent auditor, such as a CPA, to substantiate nonprofit status.
- Organizing documents: Such as articles of incorporation, a constitution, charter, trust document, or bylaws that explain the organization’s purpose.
- Evidence of actual work: Recent newsletters, bulletins, meeting minutes, activity lists, brochures, or financial information that show what the organization has done.
USPS says an application can be submitted through the Business Customer Gateway, its online portal for business mailing services. You can also check USPS’s application guidance. USPS does not publish a guaranteed processing window, so processing time varies; ask your local Post Office what to expect. Missing documents or follow-up questions can extend the process.
Do not use nonprofit prices before approval. If USPS approves the application, the organization receives a nonprofit authorization. USPS rules also require at least one mailing at nonprofit prices in each two-year period to keep the authorization from being revoked for nonuse. This is not the same as filing a routine renewal every two years. Keep the organization’s name and records current, and contact USPS if important details change.
One other form causes confusion: PS Form 3615 is a Mailing Permit Application and Customer Profile. It relates to a mailing permit, which is separate from approval to use nonprofit prices. Depending on how you mail, you may need both. USPS explains both forms in its PS Form 3615 instructions.
Campaign ideas for eligible nonprofit types
Once your organization is approved, choose a mailing that supports its own eligible work. These ideas are for organizations that qualify under the relevant USPS category; a similar organization does not qualify automatically.
- Religious organization: Invite nearby residents to a worship service and holiday community event. Sample headline: “You’re Welcome Here This Holiday Season.”
- Educational organization: Invite local families to an open house or enrollment information night. Sample headline: “Come See What Students Can Discover.”
- Scientific organization or qualifying educational museum: Announce a new exhibit, public science program, or research talk to nearby households. Sample headline: “A New Discovery Is Waiting Around the Corner.”
- Charitable organization: Recruit volunteers and promote a community food drive. Sample headline: “Help Stock the Shelves for Our Neighbors.”
- Agricultural organization: Share a member meeting, agricultural education session, or community program with rural addresses. Sample headline: “Join Us for a Day of Ideas for Local Farms.”
- Labor organization: Remind members about a meeting and share information about eligible member resources. Sample headline: “Your Next Member Meeting: What to Know.”
- Veterans’ organization: Invite the community to a post event or membership information session. Sample headline: “Join Us to Honor and Support Local Veterans.”
- Fraternal organization: Invite residents to a community fundraiser organized by the lodge. Sample headline: “Come Together for a Good Cause.”
Keep sponsors and business mentions simple. A sponsor acknowledgment may be allowed in some situations, but promotional messages or advertisements for a for-profit business can make a mailing ineligible. The rules depend on the content and arrangement. Check USPS DMM 703 before including sponsor promotions.

Common mistakes to avoid
- Assuming nonprofit status is enough: USPS considers the organization’s main purpose, actual work, financial conditions, and application documents.
- Mailing for another organization or business: An authorization is not a discount to lend or rent. The mail must be the authorized organization’s own eligible matter.
- Treating it like First-Class Mail: Nonprofit USPS Marketing Mail has different delivery timing and handling for mail that cannot be delivered.
- Using the discount while an application is pending: Wait for approval before claiming nonprofit prices.
- Forgetting the two-year use rule: Plan at least one eligible nonprofit-price mailing every two years and keep your authorization information current.
