Bates Stamp Your PDFs Without Uploading a Single Page
Free Bates numbering for discovery productions: set your prefix, start number, and digit padding, and Bates stamp PDF files sequentially, with a Begin and End Bates log for every document. Your files are processed on your own computer and never leave your browser.
Quick answer: Bates numbering stamps a unique sequential identifier, typically a prefix plus a zero-padded number like ABC000001, on every page of a document production so each page can be cited precisely. To Bates number a PDF, add your files below, set the prefix, start number, and padding, pick a corner, and download the stamped copies. Everything runs in your browser: no upload, no account, and the tool logs Begin and End Bates for each file.
Your documents never leave this browser. Every page is read, numbered, and rebuilt on your own computer. No upload, no server, no account: close the tab and nothing exists anywhere but your machine.

How to Bates Number a PDF, Step by Step
Bates numbering a PDF takes four decisions: the prefix, the starting number, the digit padding, and the stamp position. The prefix identifies the producing party or matter, usually two to six uppercase letters. The starting number is 1 for a first production; for a supplemental production it continues from the last number you produced, which is exactly why your production log records the End Bates of every volume. Padding of six digits (000001) is the common convention because it sorts cleanly and leaves room for large productions, and the bottom right corner is where reviewing attorneys, court reporters, and opposing counsel expect to find the number.
With those set, the order of your files is the order of your production: the tool numbers every page of the first file, then continues into the second without a gap, and shows you each file's range before you stamp anything. When the stamped copies download, save your originals unchanged. The unstamped set is your working copy; the stamped set is what you produce. If you later need a different format, restamp from the originals rather than stamping over a stamp.
Why a Bates Stamp PDF Tool Should Never Upload Your Documents
Most free online stampers work by uploading your PDFs to a server, processing them there, and handing back a download. For vacation photos that is fine. For litigation documents it is a problem: the files you Bates stamp are, almost by definition, case materials. They can contain attorney-client privileged communications, work product, trade secrets, medical records, or material covered by a protective order. Sending them to an unknown server means trusting an unvetted vendor's retention practices, security posture, and terms of service with exactly the documents you are obligated to protect.
This tool takes the other path. The stamping runs entirely client-side: your browser reads each file from your disk, writes the numbers onto the pages in memory, and saves the result back to your disk. No file contents are transmitted over the network, nothing is stored, and there is no account tying the activity to you. You can verify this yourself from your browser's developer tools: the network panel shows no request carrying your documents. Before producing, remember the stamp is only the visible layer; you should also remove hidden metadata from your PDFs so author names, tracked edits, and file paths do not ride along with the production.
The Bates Format: PREFIX + Zero-Padded Number (+ Optional Suffix)
ABC000001 reads as prefix ABC, number 1, padded to six digits. The prefix marks whose production it is, so different parties' documents never collide even when their numbers overlap. Padding keeps pages sorting in order in review platforms and exhibit binders: without it, ABC10 sorts before ABC2. Suffixes are rarer and typically mark volumes or confidentiality tiers. Whatever you choose, keep it consistent for the life of the case: a supplemental production continues the sequence, it does not restart it.
Bates Stamping Legal Documents for Discovery Production
Bates numbers exist because litigation runs on precise citation. When you respond to a request for production, your written responses point to documents by Bates range; when a witness is deposed, exhibits are identified by their numbers; when you move for summary judgment, the record cites specific stamped pages. A production without page-level identifiers forces everyone to describe documents by title and date, which invites disputes about what was and was not produced. The number makes the page a fixed point in the record.
The bookkeeping half of the practice is the production log. For every document you produce, the log records the Begin Bates (first page) and End Bates (last page), and your transmittal letter states the overall range of the volume, for example ABC000001 to ABC000482. Privilege logs use the same ranges to identify withheld or redacted documents. The tool above builds this log for you as it stamps and gives you a one-click copy, formatted with a column for Begin Bates, End Bates, and page count per file. If the underlying discovery documents still need to be drafted, from requests for production to interrogatories, our discovery drafting services cover that side, and our legal template library has starting points for common litigation filings.
Pro Tip: Stamp Last, After Redactions and Metadata Scrubbing
Bates numbering should be the final step before production. Apply redactions first (and flatten them so the text underneath is actually gone), scrub document metadata, convert to the agreed production format, and only then stamp. If you renumber after changing the set, previously cited ranges break, so lock the order of your files before you stamp and record the End Bates of every volume for the next production to continue from.
Do You Need Bates Numbering Software?
For most small and mid-sized productions, no. Dedicated Bates numbering software and desktop PDF suites do the same core job this free tool does: write a sequential identifier on every page in a chosen position. Paid platforms earn their keep at a different scale, when a production involves load files for review platforms, native-file productions with placeholder images, per-page confidentiality branding driven by a database, or millions of pages where throughput matters. If your production is a set of PDFs that needs clean, consistent numbers and a reliable log, the tool above covers it without installing anything or creating an account.
The honest boundary is volume and workflow, not the stamp itself. When a matter involves thousands of documents, review for privilege and responsiveness, redaction passes, and a defensible production protocol, stamping is the easy five percent. Our legal document review services handle that end to end: review, tagging, redaction, Bates numbering, and production logs, delivered ready to serve. And for the broader case workload, deposition summaries, exhibit preparation, and trial-ready organization, see our litigation support services.
This Tool Is Not Legal Advice
This free utility stamps numbers on pages; it does not decide what you must produce, withhold, or redact, and using it does not create an attorney-client relationship. Production format requirements vary by court and by case: your ESI protocol, case management order, protective order, and local rules control the numbering format, confidentiality legends, and production procedure. Confirm those requirements in your own case documents or with a licensed attorney before serving a production. We draft and process documents; you review, sign, serve, and file them.
Bates Numbering Questions, Answered
What is Bates numbering?
Bates numbering is the practice of stamping a unique sequential identifier on every page of a document set, most commonly in litigation discovery. A typical Bates number combines a short prefix identifying the producing party or matter (such as ABC or SMITH) with a zero-padded number (such as 000001), so every page in a production can be cited unambiguously: in depositions, in motions, in exhibit lists, and in meet-and-confer letters. Once a page has a Bates number, everyone in the case refers to that page by that number.
How do I Bates number a PDF for free?
Add your PDF files to the tool on this page, set a prefix (for example ABC), a start number, and the digit padding (six digits is the common convention), pick a corner for the stamp, and click stamp. The tool writes a sequential Bates number on every page of every file, in the order you arrange them, and downloads the stamped PDFs to your computer. It is free, there is no signup, and the files are processed entirely inside your browser, so nothing is uploaded anywhere.
What is the standard Bates numbering format?
The dominant convention is an uppercase alphabetic prefix followed by a zero-padded number, for example ABC000001 or SMITH000482. The prefix identifies the producing party, the client, or the matter; the padding (commonly six digits, sometimes more for very large productions) keeps numbers sorting correctly and visually uniform. Some productions add a suffix for confidentiality tiers or volumes. There is no single required format: if your case has an ESI protocol or a production agreement, use the format it specifies.
What are Begin Bates and End Bates numbers?
Begin Bates is the Bates number on the first page of a document, and End Bates is the number on its last page. Together they define the document boundaries inside a continuous production, which is why load files, production logs, and privilege logs record both for every document. This tool generates a Begin and End Bates log for each file you stamp, with page counts, and gives you both a CSV download and a one-click copy so you can put it straight into your production letter or log workbook.
Does this Bates stamping tool upload my files?
No. The files are read, stamped, and rebuilt entirely inside your browser on your own computer. There is no upload, no server-side processing, and no copy retained anywhere: the page never transmits your document contents over the network. That matters for legal work, because discovery documents are routinely privileged, confidential, or covered by a protective order, and pushing them through a third-party upload service creates a disclosure risk you do not need to take for a stamping task.
Can I Bates stamp multiple PDFs in one continuous sequence?
Yes. Add as many PDF files as you need, arrange them in production order with the up and down arrows, and the tool numbers sequentially across all files: the first page of the second file continues from the last page of the first. Each file keeps its own Begin and End Bates range in the log, and when you stamp more than one file the downloads are bundled into a single zip so nothing is missed.
Where should the Bates number go on the page?
The bottom right corner is the near-universal convention, and it is this tool's default. The number should sit in the page margin where it does not obscure content. Bottom left and bottom center are common alternatives, and top corners are occasionally used when the bottom margin is crowded, for example on forms or spreadsheets printed to PDF. If your ESI protocol or the requesting party specifies a location, follow it.
Can I stamp CONFIDENTIAL or another legend with the Bates number?
Yes. Enter the legend text, for example CONFIDENTIAL or SUBJECT TO PROTECTIVE ORDER, and the tool stamps it on every page on the opposite side of the bottom margin from the Bates number, so the two never collide. Use the exact wording your protective order prescribes: confidentiality designations are defined terms in most protective orders, and a wrong or missing legend can waive the designation for those pages.
What happens to pages that are sideways or cropped?
They are stamped where the corner is as you see it, not where it would be if the page were untouched. Two things in a real production break a naive stamp. A page a scanner fed the wrong way round carries a rotation flag, so the viewer turns it: place the stamp at the file's own bottom right and it lands on the left edge, printed sideways. And a page can carry a crop box smaller than its paper size, which is what every viewer and printer actually displays: a stamp measured against the larger size falls outside the visible area and simply does not appear, so the production letter says the pages are numbered and the pages show nothing. This tool reads both, rotates the stamp to read level, and measures the inset from the visible edge, so mixed scanned productions come out consistent.
How do I get the Begin and End Bates log into my production letter?
Two ways. Download CSV writes a file with one row per document (document name, Begin Bates, End Bates, page count) that opens straight into Excel or a privilege-log workbook, with commas and quotes in filenames escaped properly. Copy log puts the same table on the clipboard as tab-separated text for pasting into a letter or an email. The CSV is the safer of the two for a record you have to keep: browsers refuse clipboard access in some contexts, and a clipboard is gone the moment you close the tab.
Why is it called Bates numbering?
The name comes from the Bates Automatic Numbering-Machine, a hand-held stamping device patented in the late 1800s and sold by the Bates Manufacturing Company of New York. The machine advanced its number wheel automatically with each stamp, which made sequential page numbering practical for the first time, and law offices adopted it widely. The physical stampers are long gone, but the name stuck to the practice of sequentially numbering production pages.
What if my PDF is password protected or will not stamp?
Encrypted or password-protected PDFs cannot be modified without the password, so the tool flags them with a per-file error instead of producing a broken output. Open the file in your PDF viewer with the password, save an unprotected copy (or print to PDF), and add that copy. A file that fails without being password protected is usually damaged or is not a real PDF; re-export it from the source application and try again.
Do courts require Bates numbering?
No rule says every production must be Bates numbered, but the practice is effectively standard in litigation. Federal Rule of Civil Procedure 34 requires documents to be produced as kept in the usual course of business or organized and labeled to correspond to the requests, and Bates numbering is how parties make labeling and later citation workable. Many ESI protocols, case management orders, and production agreements expressly require Bates numbers and specify the format. Check the discovery orders and agreements in your own case: they control.
Will the Bates stamp cover up text on my pages?
The stamp is placed in the outer margin, about half an inch from the page edges, which clears the content area of most documents. Pages with edge-to-edge content, such as full-bleed scans, spreadsheets, or drawings, can have material near the corners, so spot-check a few stamped pages before you produce. If a corner is crowded, switch the stamp to a different position and restamp: the tool is free to rerun as many times as you need, always starting from your original files.
