Bates numbering for PDFs, in your browser

Number a whole production in one pass — prefix, sequential counter, zero-padding, and a confidentiality legend and date in the same stamp if you need them. It runs entirely inside your browser, so a privileged document never leaves your machine to get numbered.

What Bates numbering is

Bates numbering is a sequential identifier applied to every page of a document set so that any page can be cited unambiguously. Each page carries a unique number, usually with a prefix identifying the party or matter and zero-padding to a fixed width — ABC-000123.

It is named after the Bates Automatic Numbering Machine, a self-incrementing hand stamp from the 1890s. The paper is gone; the convention survives because discovery still needs every page to have one unchanging name.

Step by step

How to add Bates numbers to a PDF

  1. Open your PDF. Choose the file. It loads straight into the page; nothing uploads.
  2. Open the Stamp tool and tick Bates number.
  3. Set your scheme. Prefix ABC-, start at 1, 6 digits. The live preview above the segments shows ABC-000001 immediately.
  4. Add a legend if you need one. Tick Free text and type CONFIDENTIAL. The preview becomes ABC-000001 | CONFIDENTIAL.
  5. Position it. Drag the stamp to the bottom-right corner, or type the coordinates — the default already sits half an inch in from the corner.
  6. Save. Every page gets its own number in sequence.

Build the whole stamp from four parts

Four elements, each optional, in any order you like — drag them to rearrange and the preview updates as you drag.

  • Bates number — prefix, zero-padded counter, suffix: ABC-000123
  • Free text — a confidentiality legend, a matter name, a party
  • Date — six formats, including 2026-08-08, 08/08/2026 and 8 August 2026
  • Page numbersPage 3 of 35 or 3/35

Join them on one line with a separator of your choice, or stack them as separate lines with left, centre or right alignment.

Number only some pages without breaking the sequence

Every number is derived from the page’s real position in the source document, not from its rank among the pages you happened to select. Stamp only the odd pages and page 5 is still ABC-000005 and still reads “Page 5 of 35” — the sequence has a gap, which is the truth, rather than being silently compressed into ABC-000003.

That matters because a Bates number is a citation. A number that changes depending on which subset was stamped is not an identifier.

  • All pages, one page, odd, even, or a custom range like 2, 5-7, 10
  • Numbering and page counts always reflect the full document
  • The preview shows exactly which pages are stamped before you save

Save a numbering scheme for the whole matter

A Bates scheme is usually stable for an entire matter — same prefix, same digit count, same legend. Save it once by name and load it on every subsequent batch; only the starting number changes.

Saved schemes keep the prefix, digits, suffix, legend text, date and page-number formats, the order of the elements, and all the styling. They do not keep your document, so the same scheme works across files.

Privileged documents that never leave your machine

Most online Bates tools require you to upload the document to a server. For material under a protective order, or anything privileged, that upload is itself the problem — you are handing a copy to a third party in order to stamp it.

This tool does not have an upload step. The PDF is opened, numbered and saved by your own browser. There is no copy on any server, including ours, so there is nothing to request the deletion of afterwards.

How this works

FAQ

Bates numbering

Is Bates numbering free here?

Yes. Every feature is free while the tool is in beta — no account, no card, no page limit.

What format do Bates numbers usually take?

A prefix identifying the producing party or matter, then a zero-padded sequential number: ABC-000123. Six digits is the most common padding. A suffix is occasionally added for volume or custodian.

Can I start at a number other than 1?

Yes. Set the starting number to continue a sequence from a previous batch — start at 1501 and the first stamped page is ABC-001501.

Can I add CONFIDENTIAL alongside the number?

Yes. Enable the free-text element and it joins the same stamp block. You choose whether it sits before or after the number, and whether they share a line or stack.

Does it work on scanned PDFs?

Yes for stamping — the number is drawn onto the page like any other content. It does not read or index the scanned text; there is no OCR here.

Will it change my original file?

No. You download a new PDF; the file on your device is untouched.

Can I remove Bates numbers later?

Not with this tool. The number becomes part of the page content, which is the point — keep your unstamped original.
