How to file a federal comment — a field guide

Regulations.gov’s own banner reads “Your Voice in Federal Decision-Making,” and it is that rare government slogan which is literally, mechanically true: the Administrative Procedure Act obliges agencies to invite comment on proposed rules and to consider what arrives, and the portal is the door. This guide is the federal companion to the front page’s How a bill is handed over — the same civic machinery, one level up — written because this project is about to use the door itself and researched the mechanics on the way in. Everything below is pinned; two of the pins are the government’s own instruction sheets, which are better than most commercial guides and almost entirely unread.

The two documents worth reading before this one. The federal Tips for Submitting Effective Comments (hosted on Regulations.gov’s own download service, downloads.regulations.gov/FS-2018-0053-0007/content.pdf) and the GSA Commenter’s Checklist (mirrored by the Administrative Conference of the United States, acus.gov). Nearly every rule of craft below traces to one of them.

1. What a docket is, and what commenting actually does

A docket is the public file for one agency action: the document itself, everything the agency adds, and every comment received. For a proposed rule, the APA’s notice-and-comment machinery applies: the agency must consider relevant comments, and its answer to the significant ones appears in the preamble of the final rule — which a commenter can be alerted to, and which courts can review. For a discussion paper or request for information — the FDA’s generative-AI paper is one — there is no rule at the end of the corridor yet; comments inform whatever the agency writes next. The honest expectation for that kind of docket: no reply letter, no obligation to respond point-by-point, and real influence anyway, because the staff drafting the next document read the file first.

2. The single most important fact about the process

It is not a vote. The government’s own tips sheet says so in italics: agencies decide on reasoning and evidence, not tallies, and one well-supported comment is often more influential than a thousand form letters. Mass campaigns are routinely batched and posted as a single document. This inverts the usual civic instinct: signing a petition is the weakest form of participation here, and writing three original paragraphs about something you specifically know is among the strongest.

3. The identity screen, decoded

The form’s first real choice offers three cards:

An Individual — your name, published with the comment. The government’s guidance actively invites this where you have relevant experience: identify credentials and experience that distinguish your comment — scientist, attorney, nurse, fisherman. Vantage is evidence. The card also permits filing for another person with their consent, which is how a caregiver or translator files for someone else.

An Organization — the comment speaks for the entity, and the entity’s name carries whatever weight its expertise earns. It confers no procedural advantage; a hospital’s comment and a nurse’s comment are read by the same staff under the same standard.

Anonymous — expressly provided, in those words: “a person who does not want their name associated with the comment.” An anonymous comment is accepted, posted, and considered; the burden it carries is the same one this repository carries, namely that the argument must survive on its citations because it has nothing else. Practical rule if you choose it: keep identifying details out of the text and attachments too, since the whole submission is published.

What all three share: everything submitted is public. Comments are screened before posting, and an agency may decline to post one that is duplicate or mass-campaign material, incomplete, off-topic, spam, profane, or containing personally identifiable information. Do not put into a comment anything — a phone number, a patient detail, a trade secret — that you are not content to see on the public internet permanently.

FDA dockets ask commenters to sort themselves into a coded taxonomy — the one on this docket runs from Academia – E0007 through Individual Consumer, Health Professional – A0007, and half a dozen flavours of government. The letter families are legible from the labels themselves: A health professionals, B consumer groups, C industry and media, D trade and professional associations, E academia and other organizations, G government at each level, I the international mirror of the same set.

Two things to understand about this box. First, it is a tabulation label: it lets the agency sort and summarize who commented, and it populates the tables in whatever summary-of-comments document follows. Second, it is not a scoring rubric. Nothing in the APA or the agency’s published procedure conditions the weight of a comment on the category ticked; weight follows substance, per the same tips sheet as everything else. The right way to fill it is therefore the boring way: pick the label that is true. An Individual Consumer with a specific, sourced observation outweighs a mislabeled one, and the category that flatters is worth nothing where the category that fits costs nothing.

5. The comment box, and the craft

The web form takes text of modest length — write anything substantial as a document and attach it; the portal accepts common formats including PDF, and an attachment is not a lesser submission. The craft, condensed from the government’s own sheets:

Head the comment with the docket ID and document title. It signals care and it files correctly.

Answer the questions the agency asked, by number. Agencies pose numbered questions precisely where they want input; a comment keyed to Question 21 lands on the desk of whoever owns Question 21. You are free to comment beyond the questions, but the questions are where the agency has pre-committed to listening.

Cite by page, column, and paragraph when addressing particular language, and by comment ID when addressing another commenter.

Say who you are and why your vantage matters — one sentence, early. Then bring the thing only you know: the workflow detail, the dataset, the incident, the operating reality. Agency reviewers are instructed to look for sound reasoning and evidence, and personal experience is expressly admissible evidence.

Address the trade-offs and the opposing view. A comment that concedes what cuts against it and argues anyway reads as analysis; one that doesn’t reads as position.

Propose language where you want language changed. The most usable comment in any file is the one the drafter can lift.

You need not cover everything. The sheets say so directly: pick the issues you understand best and go deep.

6. Deadlines and mechanics

Comment periods close at 11:59 p.m. Eastern time on the stated date, and the portal enforces it regardless of the commenter’s own time zone — the door shuts mid-evening on the West Coast and mid-morning in Sydney. Submission returns a tracking number; keep it, and keep your own copy of the text. Posting is not instant — screening comes first — so an absent comment the next morning is usually a queued one, not a lost one. The two counters are different things: a docket page’s “Comments Received” counts arrivals, while the browsable file shows only what the agency has posted after screening, and the gap between them can briefly be the entire docket. (Observed live, 20 August 2026: the FDA docket in § 7 showed seventeen received and zero yet posted, two days after opening — the government’s own API, queried with its public key, returned an empty file above a full waiting room.) For a proposed rule, the portal can alert you when the final rule issues, which is where the agency’s response to comments lives.

7. The worked example

This project’s own comment on FDA docket FDA-2026-N-7874 — the discussion paper on generative AI–enabled medical devices — answers four of the paper’s numbered questions with the four things this repository exists to argue for: a duty, a record, a clock, and a name. It files pseudonymously, which § 3 above is partly written to explain, and it will be published in this folder as filed, per the shelf’s standing rule. Whatever the docket’s readers make of it, the mechanics above are how it got there — and they are the same mechanics available, at the cost of an evening, to anyone reading this.
