Presorting is the process of grouping mailpieces together by destination.
Presorting is the process of grouping mailpieces together by destination, commonly by ZIP Code, into the same bundle or tray to expedite mail delivery.

By presorting, you’re doing some of the work the Post Office would normally do to prepare your mailpieces, which can result in significant postage discounts.

Why is Presorting Important?

Lower Costs - USPS Presort Mailing is available for Standard and First Class mail. Whether done in-house or using a service, businesses can save money by presorting, especially when sending mail in large quantities. For example, for a 1 ounce single-piece flat, the USPS charges $1.00 for processing, but the presort rate is .81 per piece - resulting in a savings of $0.19 per piece. As the example below shows, for a 10,000 piece mailing, the savings can be significant.

1 10,00 $1.00 $0.81 $0.19 $1,900.00

Faster Processing & Delivery - Presorting means less work for the Post Office, so mail is processed and delivered more quickly, efficiently and accurately.

Quicker Response Rates - Faster processing and delivery increases the likelihood that recipients will respond quickly to your mailpiece.

How Do I Prepare My Mailings?

Commercial mail is prepared in higher volumes at reduced postage. To receive commercial mail pricing, the USPS recommends taking the following steps to prepare your mail:

  • Get a mailing permit (permission to mail) and pay an annual mailing fee for each class of mail (First-Class Mail and USPS Marketing Mail).
  • Pay postage using one of several convenient methods: precanceled stamps, metered postage or permit imprint.
  • Determine the size, shape and weight of your mailpiece.
  • Ensure that your addresses are accurate.
  • Presort the mailpieces (separate or sort your mail by ZIP Code).
  • Take your mail to the Post Office where you hold your mailing permit.
