Need someone to print and mail your catalog? One of the most powerful methods of advertising is through the use of a catalog. Research has shown that as many as 165 million people in the United States purchase from catalogs sent to them through the mail and they make over $1.8 billion sales. This does not even include the $100 billion or more that is purchased through business to business catalogs.

Nonprofit Mail Instruction

Once you have been approved to mail at nonprofit rates, you must make a mailing at nonprofit rates at least once during a two-year period at each office where you are authorized, in order to keep your authorization. Otherwise, your authorization could be revoked.

You will find step by step instructions below...

1. Get a copy of Form 3624, Application to Mail at Nonprofit Standard Mail Rates, from your postmaster or local business mail entry unit.

2. Fill out from 3624.

3. Submit documentation with your application to verify your nonprofit status:

1. Formative papers (articles of incorporation, constitution or charter).


2. IRS letter of exemption from payment of federal income tax.


3. Other evidence, such as a financial statement prepared by an independent auditor substantiating your nonprofit status (must include balance sheets, notes, etc.).

4. Some mailers provide additional supporting documentation:

1. List of the organization's activities during the past 12 months.


2. Financial statement showing receipts and expenditures for the past fiscal year, plus budget for the current year.


3. Other documents of operation, such as the organization's bulletins, meeting minutes, brochures, etc.

5. Submit the completed form and supporting documentation to your postmaster or at the business mail entry unit.

6. Your application will be reviewed by the Postal Service. If there are any questions, or if additional supporting documentation is needed, a postal specialist will contact you directly. It usually takes about two to three weeks for your application to be approved.
