Commercial First-Class Mail Rates: Presort Costs and Eligibility

Current First-Class Presort letter rates#

First-Class Presort can lower postage on a qualifying business mailing, but the savings must cover the extra preparation costs. Presort means grouping mail by destination and preparing it to USPS standards. You can do that work yourself or pay a mailing provider; compare the complete cost with your current mailing method.

The automation prices below apply to qualifying domestic First-Class letters weighing up to 3.5 ounces, effective July 12, 2026. They are postage only, before applicable incentives. Printing, envelopes, inserting, address preparation and provider charges are separate.

A mailing can contain letters at different prices. Its total quantity does not establish the lowest tier. Ask for the expected piece count and postage subtotal at each tier, using the actual address list and preparation. The USPS price-application rules (opens in new tab) determine which groups qualify.

Automation is one preparation route. USPS also publishes nonautomation prices for machinable and nonmachinable letters, plus separate commercial card and flat schedules. A piece that cannot use the automation table needs the correct alternative schedule, not an assumed discount from one of these rows.

For ordinary stamps, metered postage and retail prices by weight, use the First-Class Mail rates guide. Metered postage and First-Class Presort are different price categories: printing postage through a meter does not, by itself, qualify the mailing for Presort.

Which mailings qualify for Presort?#

USPS sets a 500-piece mailing minimum for First-Class Presort, with additional requirements for the chosen preparation category. That is a mailing requirement, not a promise that every group earns the five-digit price. The letter's shape, weight, addresses and preparation also matter. See DMM 233, First-Class commercial eligibility (opens in new tab).

The five-digit automation tier generally requires qualifying groups of at least 150 pieces; USPS specifies tray and overflow rules. Regional and mixed preparation have their own conditions. Your provider or USPS business-mail entry office should confirm the categories for the actual mailing before you use them in a budget.

If your own job is smaller, ask a mailing provider whether it can accept it as part of a qualifying combined mailing. Do not assume the provider's minimum order matches the USPS mailing minimum, or that combining jobs guarantees a particular rate. Ask what it will charge for your quantity.

The contents come first when choosing the mail class. Bills, statements of account and personal correspondence generally belong in First-Class Mail rather than advertising mail. A large quantity does not turn them into USPS Marketing Mail. If you are sending eligible advertising, compare the bulk-mail postage rates and content requirements before paying for First-Class treatment.

Preparation and fees depend on how you mail#

Automation prices require suitable mailpieces, accurate addresses, the applicable Intelligent Mail barcodes, sorting and documentation. Full-Service has additional barcode and electronic-documentation requirements; nonautomation Presort follows separate standards.

Address preparation is part of the work. Mailers claiming First-Class Presort or automation prices must meet applicable address-quality standards, including USPS Move Update requirements (opens in new tab). Ask who cleans and updates the list, what is included in the quote, and how undeliverable addresses are handled before printing.

You can handle the preparation yourself or pay a provider to handle it. That choice also affects which fees you pay directly.

Permit imprint is one postage-payment method. Do not add an application fee automatically to a mailing using another permitted method, an existing account or a provider's arrangement. A provider may enter client mail under its own paid or exempt Presort status; ask which permit and fees your quote uses. Its postal arrangement does not mean its preparation service is free.

Full-Service eligibility can change the annual-fee calculation, but it does not automatically remove a required permit-imprint application fee. Confirm the status with USPS or the provider. A quote that includes Full-Service, Seamless Acceptance or another incentive should identify the program, its conditions and the reduction already included in the price.

Full-Service can also provide qualifying address-correction services and mail-processing visibility. Barcode scan information is not a recipient's signature or a guaranteed delivery record. If a particular delivery receipt is part of your task, establish that requirement before comparing ordinary First-Class postage.

Work out the savings before paying for setup#

Consider an illustrative annual plan of four mailings, each containing 5,000 qualifying one-ounce letters. That is 20,000 letters during the year. For this example, every letter qualifies at the published Mixed automation base price of $0.707. The actual tier mix must be confirmed for a real mailing; this example assumes no additional incentives.

Using a $0.82 stamp on each letter would cost $16,400 in postage for the year. At $0.707, the Presort postage would be $14,140. The difference is $2,260, before paying for any extra work needed to obtain that price.

Now assume this is your first year using your own new permit imprint, both $390 fees apply, and neither is waived. The $780 in applicable fees leaves $1,480 available to cover extra preparation and service costs before the Presort approach becomes more expensive than the stamped comparison.

That $1,480 is a cost allowance, not a promised saving. Across the four planned mailings, the fee allocation is $195 per mailing and the remaining allowance is $370 per mailing. Printing, envelopes, inserting, labor and transport must still be compared on the same basis for both methods.

If you already pay the $0.78 one-ounce metered price, use that baseline instead. Annual metered postage would be $15,600, so the gross postage difference falls to $1,460. After the same illustrative $780 in fees, only $680 for the year, or $170 per mailing, remains for additional costs. See the USPS rates reference for the current retail comparison.

An existing permit, an applicable exemption or a provider handling the mailing changes those inputs. For a genuine one-off mailing, a newly required annual fee may belong entirely to that job. For recurring work, allocate it across the volume you realistically expect to send during its valid period.

To estimate your break-even volume, subtract extra preparation costs per letter from the postage saving per letter. Then divide extra fixed costs by that remaining saving per letter. Round up to a whole letter. If the remaining saving is zero or negative, sending more letters will not recover the fixed costs. Use actual costs or a provider quote.

What a complete Presort quote should include#

Send the provider a representative finished mailpiece and the information needed to assess your mailing. Ask the quote to identify:

• The letter's shape, finished weight, contents and quantity.
• The expected piece count, price and postage subtotal for each preparation tier.
• Printing, envelopes, inserting and other materials or production work.
• Address correction, sorting, barcodes, documentation and delivery to USPS.
• Permit ownership, applicable setup or annual fees, minimum charges and items you must pay separately.
• Any incentives already deducted, their eligibility conditions and the total payable for the agreed scope.

Compare the same job on both sides. A postage-only price should not be compared directly with a price that includes printing and mailing. Confirm that the quoted preparation fits your sample and address list before you commit to production.
