What Is A Bulk Mail Indicia? 

A bulk mail indicia, also known as a permit imprint, is a printed postage mark used on commercial mailings in place of a stamp. This mark indicates that postage has been prepaid for a bulk mailing, which must contain at least 200 identical pieces or 50 pounds of mail, and is submitted at a discounted rate. An indicia is printed directly onto the mailpiece as part of the design, which is more efficient for high-volume mailings than applying individual stamps.

Who Should Use a Permit Imprint?

Permit imprints are specialized tools best suited for professional mailers, mail service providers, and large organizations that send consistent, high-volume mailings.

For individuals and most businesses, it is highly recommended to avoid getting your own mailing permit and designing your own indicia. The process involves strict USPS rules regarding design, placement, and mail preparation, and a single error can result in a costly reprinting of your entire mail run.

Instead, businesses should work with a mail service provider or mail house. These professionals use their own permits and expertise to handle the entire process. They will provide or help incorporate the correct indicia into your mailpiece design, using their own permit number, so you can avoid the fees and complex requirements.

Designing a Permit Imprint Indicia

The USPS has strict rules for the design and placement of an indicia. Failure to follow them can lead to your entire mailing being rejected. The indicia must appear in the upper-right corner of the mailpiece, be legible, and not be typewritten or hand-drawn.

A standard permit imprint indicia includes these required elements:

• Line 1: The class of mail (e.g., "First-Class Mail," "USPS Marketing Mail," etc.).
• Line 2: The words "U.S. Postage Paid." This is now suggest to be on two lines like below.
• Line 3: The city and state where the mailing permit is held.
• Line 4: The word "Permit" followed by the permit number.

It's also possible to use a company permit imprint, which omits the city, state, and permit number but includes the company name. This is useful if a professional mailer handles mailings from multiple post offices but wants to use a single design.

The Connection to a Mailing Permit

To use an indicia, a mailer must have a mailing permit, which is the permission granted by the USPS to use a specific postage payment method for commercial mailings.

• Application Process: To get a permit, you must complete PS Form 3615, submit it to the post office where you'll mail, and pay the required fees.
• Fees (as of July 2025): The one-time application fee is $370.00 to set up your account. In addition, there is an annual mailing fee of $370.00 for each class of mail.

Frequently Asked Questions (FAQs) About Permit Imprints

Q: What is the main difference between a permit imprint and a stamp? A: A permit imprint is a printed postage mark used for commercial bulk mailings (200 pieces or more), while a stamp is used for individual, First-Class mail. An indicia requires a mailing permit and an advance deposit account with the USPS.

Q: Do I need a mailing permit to use an indicia? A: Yes and no. For most commercial mail, a permit is required but you do not need to acquire your own permit. You can have a mail service provider mail for you using their own mailing permit and indicia. The exception is the Every Door Direct Mail (EDDM) Retail program, which has a special, universal indicia that does not require a mailing permit at all.

Q: Can I use a permit imprint for a single letter? A: No. A permit imprint is only valid for commercial mailings that contain at least 200 identical pieces or 50 pounds of mail. You cannot use it to send a single letter.

Q: If I use a mail service provider, do I still need my own permit? A: No. A major benefit of using a mail service provider is that you can use their permit. This saves you from having to pay the application and annual fees and ensures your indicia is designed and placed correctly according to USPS regulations.
