What Is Presort Mail?
A plain-English guide to USPS presort programs, 2026 postage rates, and how businesses on the Delmarva Peninsula save money on every mailing.
Quick Answer
Presort mail is a USPS discount program in which a mailer (or their mail house) sorts pieces by ZIP code or carrier route before drop-off. Because USPS skips its own sorting step, it lowers the postage rate. In 2026, First-Class presort starts at $0.593 per piece versus $0.74 for a single stamp—a savings of about $0.147 per piece. Marketing Mail presort starts at $0.178 per piece.
How Presort Mail Works
Every piece of mail that enters the postal system must be sorted—either by USPS machines at a processing facility or by the mailer before drop-off. When a mailer does the sorting work, USPS rewards them with a reduced postage rate called a presort discount.
The more precisely a mailing is sorted, the larger the discount. USPS recognizes three primary sort levels:
- 5-Digit Presort — all pieces in a bundle share the same 5-digit ZIP code. This earns the highest discount.
- 3-Digit / SCF Presort — pieces share the same first three digits of their ZIP code (same Sectional Center Facility). Earns a mid-level discount.
- AADC / Mixed AADC — pieces are sorted to the same Automated Area Distribution Center. Earns the base presort discount.
A certified mail house like Mail Movers handles all sorting, tray preparation, Intelligent Mail barcode (IMb) application, and USPS electronic documentation (eDoc) on your behalf. You provide the mailing list and printed pieces; we do the rest.

Frequently Asked Questions About Presort Mail
What is presort mail?
Presort mail is a USPS program that lets mailers sort letters, flats, and parcels by ZIP code or carrier route before drop-off. Because the post office skips its own sorting step, it rewards mailers with postage discounts of up to $0.15 per piece compared to single-piece First-Class rates.
How much can I save with presort mail?
Savings depend on mail class and sort level. First-Class presort starts at $0.593/piece versus $0.74 for a single stamp—a savings of about $0.147 per piece. Marketing Mail presort starts at $0.178/piece. On a 10,000-piece mailing, that can mean $1,470–$5,620 in postage savings.
What is the minimum quantity for presort mail?
USPS requires at least 500 pieces for First-Class Presort and at least 200 pieces (or 50 lbs) for Marketing Mail. Smaller quantities can still qualify if combined with other mailers through a commingling service.
What is the difference between presort and standard mail?
"Standard mail" is an older term for what USPS now calls Marketing Mail. Both terms refer to the same class: bulk, non-time-sensitive advertising mail that is presorted to earn discounts. First-Class presort is a separate, faster class with forwarding and return service.
Do I need to sort the mail myself?
No. A USPS-certified mail house like Mail Movers handles all sorting, barcoding, tray preparation, and electronic paperwork (eDoc) on your behalf. You simply provide the mailing list and printed pieces.
What is commingling and how does it help small mailers?
Commingling pools your pieces with mail from other clients to meet USPS volume thresholds. This lets mailers with fewer than 500 pieces still qualify for presort discounts they could not achieve on their own.
How long does presort mail take to deliver?
First-Class presort mail typically delivers in 2–5 business days, the same as regular First-Class. Marketing Mail presort typically delivers in 3–14 business days depending on destination and season.
What is Full-Service presort?
Full-Service presort adds Intelligent Mail barcodes (IMb) and electronic documentation to standard presort. It unlocks an additional per-piece discount and provides real-time mail tracking through USPS Informed Visibility.
Can nonprofits use presort mail?
Yes. Nonprofits approved by USPS can use Nonprofit Marketing Mail rates, which are even lower than standard Marketing Mail presort rates—often around $0.10–$0.15 per piece for qualifying organizations.
