Bates numbering (DEF000001, DEF000002…) identifies every page of an entire production uniquely, so lawyers can cite exact pages across hundreds of documents. Page numbers (1, 2, 3) restart in every document and only organize the file they are in. Rule of thumb: if pages will ever be cited in a proceeding, use Bates; if it is an ordinary report or memo, page numbers are enough. Below is the full side-by-side comparison — and you can apply either one to a PDF free, entirely in your browser.

| Bates numbering | Page numbers | |
|---|---|---|
| Looks like | DEF000001, CONF000874 | 1, 2, 3… or "Page 4 of 60" |
| Scope | Unique across the whole production | Unique inside one document |
| Sequence | Runs unbroken across all files | Restarts at 1 in every file |
| Identifies | The page + the producing party | Position within the document |
| Purpose | Citation in proceedings | Navigation and reading |
| Used for | Discovery, exhibits, bundles | Reports, contracts, books, memos |
Choose Bates whenever a page needs to be pointed at from outside its own document. Litigation discovery is the canonical case: "see Bates DEF000042" names one page in a 10,000-page production with zero ambiguity. Arbitration exhibits, regulatory production sets and trial bundles work the same way — every participant shares one page language. Bates labels also carry the producing party in the prefix, so DEF000120 and PLT000120 are visibly different sources even when quoted side by side. Courts and discovery protocols in common-law jurisdictions expect this; producing unnumbered pages into a contested matter is asking for a citation dispute. Background on the system: What is Bates numbering?
For everything that is not a formal production, plain page numbers are the better choice: they are lighter, universally understood, and don't imply a legal context that doesn't exist. Contracts, annual reports, white papers, e-books, internal memos, invoices — all of these are read within their own document, where "page 47" is perfectly clear. Stamping DEF-prefix labels on a quarterly report would confuse the reader and misrepresent the document's status. Our Add Page Numbers tool stamps clean 1-2-3 numbering (or "Page X of Y") onto any PDF in your browser, with a choice of position and starting number.
Productions frequently carry both: the document's own page numbers stay in their original footer for readability, and the Bates label is stamped in a separate corner for citation. The only rule is to keep the two visually distinct — page numbers centered at the bottom, Bates labels at the bottom right, for example — so nobody accidentally cites a plain page number as a Bates reference. If you are preparing a formal production, read the full workflow first: How to add Bates numbers to legal documents.
Two other labels get confused with these. A watermark like CONFIDENTIAL or DRAFT marks the document's status — it adds no page identity and no citation power. A document control number identifies the document as a whole ("Document 47"), while Bates identifies each page within it. A confidential production typically carries all three roles at once: a CONFIDENTIAL watermark for status, plain page numbers for reading, and a CONF-prefix Bates label on every page for citation. Use our watermark tool for the status mark, the page-number tool for navigation, and the Bates tool for citation identity.
Whether you stamp Bates labels or plain page numbers, the privacy question is the same — and it matters more for legal documents than for almost anything else. Adobe Acrobat's web tools require an account and process your upload on Adobe's servers; by design, your full document leaves your machine. Many "free Bates stamp" sites combine an upload with a per-page fee and retention windows buried in their privacy policies. For discovery productions and privileged material, that is an unnecessary exposure: sequential stamping is trivial local bookkeeping on a file you already hold.
Both stamping tools on this site — Bates numbering and Add Page Numbers — draw the labels onto the pages with pdf-lib entirely in your browser. Nothing is uploaded, there is no account, no quota and no server copy. Open the network tab of your browser's developer tools while either tool runs: you will not see a single upload. That is the difference between a tool whose business model needs your file and one whose architecture doesn't. For the broader picture on upload-based PDF tools, see Are online PDF tools safe?
Page numbers (1, 2, 3) restart in every document and locate a page inside that file only. Bates numbers (DEF000001, DEF000002…) are unique across an entire production of many documents — the counter runs unbroken from one file to the next, and the prefix identifies the producing party. Page numbers organize a document; Bates numbers identify pages for citation in legal proceedings.
Bates numbering is expected whenever pages must be cited across a multi-document production: litigation discovery, arbitration exhibits, regulatory productions, and trial bundles. Courts and opposing counsel need "see Bates DEF000042" to point at one unique page. Simple page numbers are fine for ordinary business documents, reports and memos with no citation requirement.
Yes, and productions often do: original page numbers stay in the document's own footer (useful for reading), while the Bates label is stamped in a separate corner for citation. Keep the two visually distinct — for example page numbers centered at the bottom, Bates labels at the bottom right — so nobody cites the wrong one.
No. Watermarks mark status ("CONFIDENTIAL", "DRAFT"); Bates labels identify pages for citation. A confidential production typically carries both: a CONFIDENTIAL watermark and a CONF-prefix Bates label on every page. Use our watermark tool for the status mark and the Bates tool for the page identity.
Use the Add Page Numbers tool for simple sequential numbers (1, 2, 3) on any document, and the Bates Numbering tool for prefixed, zero-padded production labels (DEF000001) on legal matters. Both run 100% in your browser — no upload, no account.
Security depends on where the processing happens, not on the label type. Server-upload tools receive your full document either way — a real risk for legal productions. Browser-only tools like these stamp either label type without the file ever leaving your device, which is why they are the safer choice for both.
