Periodical Class Bulk Mail Prices and Requirements

Periodical Class bulk mail is used for mailing newspapers, magazines and other regularly-scheduled publications, including college course catalogs, bus schedules, and legal reporting services. To qualify, a publication must be published at specified intervals, at least four times per year, to continue indefinitely.

A product catalog is not eligible for Periodical Class, but would usually qualify for Marketing Mail or Bound Printed Matter bulk mail prices.

Periodical Class mailers must keep accurate records for each issue published, including the number of copies printed, how the copies were distributed, and lists of subscribers and/or requesters.

Periodical Class postage is the most complicated of all USPS services to calculate. The only way to really know what a particular mailing might cost is to run the circulation list through software like Postage $aver. But our postage calculator will at least give you an idea of the pricing.

The postage price for Periodical Class bulk mail depends on the size and weight of the mail piece, the distance to its delivery facility, how much of the publication is advertising, and whether the recipient is in the same county as the sender. There are also discounts for taking your mailing to a major sorting facility.

There's a pretty good chance that you'll pay several different postage rates on different pieces in the same mailing, depending on where the pieces are going.

Nonprofits get additional discounts off of the commercial Periodical Class rates, and there are also discounts for publications for classroom use and for certain publications related to agriculture.

After calculating the postage for each piece, there are also charges for each "bundle" of mail, and for each tray or sack. For mailings that are large enough to require pallets, there is a charge for each pallet. You can use our Periodical Class bulk mail postage price calculator to find the postage prices available for your mailing.

(ADCs are Area Distribution Centers, mail sorting hubs that typically serve a large part of one or more states.)

If you already have the list you want to mail to, we recommend you download a free demo copy of our Postage Saver bulk mail software, and run your list through it. It will figure out the exact postage you'd pay for mailing that specific list, and let you try various options.
