USPS Bound Printed Matter is a special postal category that offers low rates for catalogs, books and other bound printed materials. Bound Printed Matter rates can be used for pieces weighing up to 15 pounds, and are usually the cheapest rate available for pieces that qualify. (For pieces under one pound, Marketing Mail is sometimes cheaper, especially for nonprofit mailers.)

Postage Saver software makes postal bulk mailing easy For example, the Bound Printed Matter rate for a two-pound box is just $3.77 per piece for up to 299 pieces, and drops to $1.33 - $2.36 (depending on where it's mailed) for shipments of more than 300 pieces. The same parcel sent using USPS Parcel Select Ground ground would cost $7.53 - $11.25, depending on distance.

See our rate calculator below to get the postage for your mail piece.

To qualify as Bound Printed Matter: Bound Printed Matter rates are available for flat-sized mail and for parcels. There is no minimum quantity, but there's an extra price break for mailings of 300 pieces or more.

If your contents don't meet those requirements, you can probably use one of the other bulk mail categories. For flat-sized or letter-sized mail, check out Marketing Mail. For parcels, see our bulk parcel shipments page.

Bound Printed Matter rates can be used only for domestic mail (including military addresses, Puerto Rico and U.S. territories and possessions). If you need to send large quantities of international mail, check out this guide.

What are the permit fees for using Bound Printed Matter rates?

You must have a mailing permit for Bound Printed Matter before you can use Bound Printed Matter rates. There are two fees that you may (or may not) need to pay to get your permit: a Permit Imprint Authorization Fee and an Annual Mailing Fee. These fees are paid directly to USPS. A vendor cannot issue a mailing permit to you.

Bulk Mail IndiciaThe Permit Imprint Authorization Fee ($275 one time) allows you to use a "postage paid" box (also called "indicia") on your mail instead of stamps or meter postage. For Bound Printed Matter, the postage paid box is required. Stamps or meter postage are not allowed.

The Annual Mailing Fee ($275 yearly) is for authorization to mail at Bound Printed Matter rates.

Here are the rules for which fees are required for Bound Printed Matter mailers: How to apply for a Bound Printer Matter permit: You can apply online for a Bound Printer Matter permit and for a permit imprint authorization. Or, you can apply in person using USPS form 3615.

Either way, you'll need to choose a post office where your permit account will be kept. You should select the post office where you expect to take your mail. That would normally be the post office that is most convenient for you, but not all post offices accept bulk mail, and sometimes you can get a better postage rate by taking your mailings to a regional sorting center.

In suburban and rural areas, many post offices accept bulk mail. But in major cities, bulk mail is generally accepted only at the regional sorting center and sometimes at a few smaller post offices.

To find out whether bulk mail is accepted at a specific post office, find the post office using the post office locator on USPS.com, and see if it shows "Bulk Mail Acceptance Hours" in the chart of that office's hours. To find all of the post offices in your area that accept bulk mail, call the USPS District Business Mail Entry office for your area, which you can find using the USPS locator screen.

If you're not far from the USPS sorting center for your area, and much of your mail is going to addresses processed by that sorting center, you'll get better postage rates by mailing your bulk mail from that sorting center (if you're mailing 300 pieces or more at one time). You can see your possible savings by using the rate calculator above. If you will be mailing from the sorting center, you should get your permit at that center rather than at your neighborhood post office.

USPS "Mailer ID" number: When you get your permit, you will be assigned a "Mailer ID" number, which is NOT the same as your permit number. The Mailer ID number is a 9-digit number that begins with 9 (unless you are a very large volume mailer). Make sure you find out what it is, because you will need your Mailer ID when preparing your mailing.

What software and other supplies do I need to prepare Bound Printed Matter?

To prepare your mail, you'll need software to do the required sorting and to print the necessary postal paperwork. You'll also need USPS mailing sacks, and, for flat-sized mail and non-rectangular parcels, rubber bands.

Bound Printer Matter presort software: To qualify for Bound Printed Matter rates for mailings of 300 pieces or more, your mail must be sorted and placed in mailing sacks according to very detailed USPS rules.

It's not just sorting by zip code - various zips must be combined with others, depending on quantity, where you're mailing from and to, the size of the mailpiece, etc... It's literally a book full of sorting rules, and the routings change each month.

You'll also need to print paperwork for submitting your mailing and special barcoded tags to label each mailing sack. And, for parcels, you'll need to print USPS tracking labels and to upload a special tracking file to USPS.

For a shipment of less than 300 pieces, the tracking labels and tracking file are not required, and you have the option of sorting by postal zone instead of by combinations of zip codes. But you get free tracking and hopefully faster delivery by doing the complete preparation as if there were at least 300 pieces.

The easiest way to do all of this is to use software designed to prepare bulk mail. Our Postage $aver Pro software prepares letter-size and flat-sized mailings, including Bound Printed Matter flats. Postage $aver for Parcels prepares various parcel categories including Bound Printer Matter parcels.

USPS sackMailing containers: You'll need to sort your mail into specific mail sacks before you can mail it at Bound Printed Matter rates. The sacks are provided by the USPS at no charge. You can pick them up at the post office where you are mailing your bulk mail.

Size 64 rubber bands: If you are preparing flat-sized mail, or irregular-shaped parcels less than 10 pounds, you'll need rubber bands to bundle your mail. You can buy a bag at your favorite office supply store.


Congratulations! You're now ready to move on to actually preparing your mailing.
