How to Fill Out and Submit PS Form 3541: PostalOne! Filing and Records

PS Form 3541 is the postage statement Periodicals publishers file with each issue or edition they enter into the mail. To complete it, gather your piece counts, weights, advertising percentage, and container details; fill in only the parts of the form that match your mailing type; roll those part totals up to the Postage section on page 1; then submit electronically through PostalOne! or in person at a Business Mail Entry Unit. The current version is dated January 2026 and is available at about.usps.com or at any BMEU.1United States Postal Service. Postage Statement – Periodicals

Only a publisher or registered news agent with authorized Periodicals mailing privileges may use this form. It cannot be used for USPS Marketing Mail, First-Class letters, or any mailing outside the Periodicals class. Each Form 3541 covers one issue or one edition; multiple editions of the same issue require separate statements.2PostalPro. Periodicals

What to Have in Hand Before You Start

Missing any of the following will stall your mailing at the acceptance window.

  • Publication title and publication number. The number appears on your authorization and in your identification statement, formatted like “USPS 876-690” (or an ISSN if assigned).3United States Postal Service. 207 Periodicals
  • Issue date and mailing date. The issue date on the form must match the publication itself.
  • Frequency of publication, matching the frequency stated on your original permit authorization.
  • Weight per copy. Weigh a random sample of at least 10 copies, divide by the number of copies, and express the result in decimal pounds rounded to four decimal places.4United States Postal Service. Domestic Mail Manual 207 – Commercial Mail: Periodicals
  • Advertising percentage, rounded to two decimal places.
  • Piece counts broken out by presort category (carrier route, 5-digit, 3-digit, ADC, mixed) and by destination zone (Local through Zone 8, plus mixed).
  • Container counts: number and type of sacks, flat trays, or pallets, and each container’s presort level.

Working Through the Form

The form runs eight pages, but you complete only the parts that apply. The official instructions on the form itself lay out a six-step sequence.1United States Postal Service. Postage Statement – Periodicals

Page 1 Setup

Fill in the mailer and mailing sections at the top: publication title, publication number, issue date, mailing date, number and type of containers, and whether this is a consolidated postage statement. Leave the Postage section blank for now. It receives totals from the inner parts after you finish them.

Parts A Through F and Part P

Jump to the parts that fit your mailing:

  • Part A: In-County piece and pound prices. Use only if your mailing qualifies for In-County rates.
  • Part B: Outside-County pound prices. Enter the zone-by-zone weight breakdown, split between advertising and nonadvertising pounds.
  • Part C: Outside-County piece prices. Record piece counts by presort level (carrier route, 5-digit, 3-digit, ADC, mixed ADC).
  • Part D: Outside-County bundle prices. Enter the number of bundles at each presort level.
  • Part E: Outside-County sack, tray, and pallet prices. Complete the distribution section to determine container-level charges.
  • Part F: Outside-County Ride-Along prices, for extra enclosures riding with a host Periodicals piece.
  • Part P: Periodicals Pending Authorization. If your publication is still awaiting full approval, check the applicable pending class and calculate pending postage using the percentage in DMM 207.5.2.3.

In-County-only mailings need Part A. Outside-County mailings need the applicable combination of Parts B through F. Each part has a Part Total box. Transfer those totals to the corresponding lines in the Postage section on page 1, then add them together for Total Postage.1United States Postal Service. Postage Statement – Periodicals

Part Z

Part Z is display-only. It summarizes promotions, discounts, or incentives already calculated elsewhere on the statement and does not feed into your postage total.1United States Postal Service. Postage Statement – Periodicals

Certification

The certification on page 1 must be signed by the publication’s owner or an authorized agent, with a telephone number included. The signature certifies that all information is accurate, that the mailing complies with postal standards, and that the mailing contains nothing prohibited by law. An agent who signs certifies authorization to bind the owner and may be personally liable for deficiencies caused by matters within the agent’s knowledge or control.1United States Postal Service. Postage Statement – Periodicals Attach all completed pages together when you submit, and leave out any blank pages for parts that do not apply.

Getting the Advertising Percentage Right

USPS charges different pound rates for advertising and nonadvertising content, so this number drives a real chunk of your postage bill. Measure both portions using column inches, square inches, pages, or any other recognized unit, but use the same unit for both. One full page of advertising equals one full page of nonadvertising regardless of white space. A blank page or border counts as advertising only if someone paid for that space; otherwise, borders and margins are excluded entirely. Advertising printed on envelopes and wrappers must also be included. Round to two decimal places and enter the result on page 1.4United States Postal Service. Domestic Mail Manual 207 – Commercial Mail: Periodicals

You must also file a marked copy of each issue with the postmaster at your original entry office or an additional entry office. On the first page of the marked copy, show the total units and percentage of space devoted to advertising and nonadvertising. If you publish more than one edition of an issue, submit the main or most prominent edition and keep the others available for USPS review on request. Two alternatives skip the marked-copy requirement: certification through the Periodicals Accuracy, Grading, and Evaluation (PAGE) Program, or participation in the Alternate Marked Copy process. Both require USPS approval in advance.4United States Postal Service. Domestic Mail Manual 207 – Commercial Mail: Periodicals

How Periodicals Postage Is Priced

Periodicals postage is layered, not a single rate, which is why the form has so many grids. The pound price depends on the zone and on whether the weight is attributed to advertising or nonadvertising content. Advertising pounds generally cost more. The piece price depends on how finely you presort: carrier-route pieces cost the least per piece, mixed-ADC pieces the most. Outside-County mailings add bundle prices based on bundle presort level and container prices based on whether you use sacks, trays, or pallets and how finely presorted each container is.3United States Postal Service. 207 Periodicals

Submitting the Form

You have two paths.

Electronic Submission Through PostalOne!

Most high-volume Periodicals mailers submit electronically. USPS accepts electronic documentation (eDoc) through three methods:6PostalPro. Electronic Documentation (eDoc)

  • Postal Wizard, a manual entry tool on the PostalOne! website. It handles Full-Service mailings under 10,000 pieces and supports only simple mailings.
  • Mail.dat, a mailing database generated by most commercial mail-preparation software. It carries all information about the mailing except the addresses. This is the established industry standard.
  • Mail.XML, a communication format from more advanced software packages that sends only the required mailing information directly to USPS.

After uploading, review the calculated totals on the confirmation screen and authorize payment from your advance deposit account. The system generates a tracking ID once the statement is accepted.

In-Person at a BMEU

Bring the completed Form 3541 and the physical mailing to your local Business Mail Entry Unit. A mailing requirements clerk reviews the statement against a sample of the actual mailpieces, checking items such as the advertising percentage, stated frequency, eligibility, postage payment, and the limit on nonsubscriber copies.7APWU. Business Mail Acceptance Once verified, postage comes out of your advance deposit account.

Records to Keep After Filing

USPS requires publishers to retain records for each issue for a minimum of three years from the issue date. Records for paid subscribers must be kept for at least 12 months following the issue date.8United States Postal Service. DMM Revision: Periodicals Requester Records Requirements At least once a year, USPS independently verifies the advertising percentage you reported by measuring one issue.4United States Postal Service. Domestic Mail Manual 207 – Commercial Mail: Periodicals

Mistakes That Bounce Statements

The same handful of problems come up again and again at the acceptance window. Check for each before you submit.

  • Advertising percentage errors: using the wrong unit of measure, leaving out wrapper advertising, or failing to round to exactly two decimal places. A mismatch between your marked copy and the form triggers review.
  • Weight-per-copy rounded too aggressively. The DMM requires four decimal places (0.1875 pounds, not 0.19), and short rounding changes the total-weight calculation and the postage owed.4United States Postal Service. Domestic Mail Manual 207 – Commercial Mail: Periodicals
  • Exceeding the nonsubscriber cap. Nonprofit and Classroom publications that go over the 10-percent limit on nonsubscriber or nonrequester copies must pay regular prices on the excess and report those copies on a separate Form 3541.1United States Postal Service. Postage Statement – Periodicals
  • Part totals that do not add up to the Total Postage on page 1. The clerk will send you back to find the discrepancy.
  • Missing marked copy. Showing up at the BMEU without one delays acceptance. File it in advance or bring it to the window.
  • Stale frequency. If your publishing frequency has changed but you have not filed a reentry application, the frequency on the form will not match USPS records.

Errors in the initial numbers can produce revenue deficiency assessments after the fact, and the certification you sign makes the owner liable for any underpayment. A few minutes checking the math before submission is cheap insurance.
