What is presorted First Class mail

Presorted First-Class Mail is a category of mail in the United States that includes letters, postcards, and flats (large envelopes) that meet specific sorting requirements before being handed over to the United States Postal Service (USPS). The primary characteristic of Presorted First-Class Mail is that the mailpieces must be presorted by the mailer based on certain criteria, such as ZIP codes or destination addresses.

Key features of Presorted First-Class Mail include:

  • Presorting Requirement: Mailers are required to presort their mailpieces based on destination ZIP codes to receive discounted postage rates. This means grouping the mail by ZIP code in a specific order before submitting it to the USPS.

  • Barcoding: In addition to presorting, mailers often include intelligent mail barcodes (IMb) on their mailpieces. Barcodes help automate the sorting process at USPS facilities, leading to more efficient processing and faster delivery.

  • Get Postage Discounts: The presorting and intelligent mail barcoding efforts made by mailers make mail processing more cost-effective for the USPS. In return, the mailers are eligible for discounted postage rates compared to regular First-Class Mail.
