## Fast answer: how to Bates number a PDF

To Bates number a PDF, use dedicated Bates stamp software that applies sequential identifiers to every page. With BatesFast you open the app in any browser, drag and drop your PDF files, set a prefix (for example, **ABC**), a starting number, and digit padding, choose where the stamp sits on the page, then click Run. BatesFast stamps each page locally in your browser, so the PDF is never uploaded to a server, and continuous numbering carries the Bates range across every file in the batch. You can then download the stamped PDFs individually or as a ZIP, optionally renamed with their first and last Bates numbers. The first full production is free after Google sign-in; continued use is a one-time $199 purchase per device, excluding tax — a practical alternative to Bates numbering a PDF in Adobe Acrobat.

## What is Bates numbering on a PDF?

Bates numbering on a PDF is the practice of stamping a unique, sequential identifier onto every page of a PDF file. The name comes from the Bates Manufacturing Company, whose mechanical numbering machines stamped paper documents for over a century. Today the same job is done digitally: a PDF Bates stamp writes a fixed prefix plus an incrementing number — such as **SMITH000001**, **SMITH000002** — into a corner of each page.

Legal teams rely on Bates-numbered PDFs so that a deposition, a motion, or opposing counsel can reference a single page precisely. “Please turn to SMITH000512” is unambiguous in a way that “page 512 of the third file” is not. The same discipline helps medical records teams, compliance departments, and corporate legal groups keep large productions organized and defensible.

Adobe Acrobat Pro can Bates number a PDF, but it is a full PDF suite priced on a recurring subscription. If Bates numbering is the job you need, a purpose-built browser workflow may be simpler.

| Need | BatesFast | Adobe Acrobat Pro |
| --- | --- | --- |
| Price | $199 one-time | Recurring monthly subscription |
| Install | None — runs in the browser | Desktop install required |
| Where files go | Stay on your device (client-side) | Local, but cloud features may sync |
| Batch + image inputs | PDF, JPEG, PNG, TIFF in one run | Supported non-PDFs are converted to PDF |
| Output file naming | Optional Bates range in filenames | Output Options can add Bates numbers to filenames |

## Bates numbering confidential PDFs without uploads

Discovery PDFs are often privileged work product or HIPAA-sensitive medical records. BatesFast processes every page client-side in your browser, so the source PDF is never transmitted to a server. That keeps confidential productions inside your control while still giving you batch stamping, continuous ranges, and exportable Bates indexes.

## Bates numbering PDF format best practices

A clean, consistent Bates format prevents renumbering headaches later. Follow these rules when you stamp a PDF production:

- Use a consistent alphabetic prefix per producing party (for example, SMITH or DEF).
- Zero-pad digits to cover your largest production — six digits (000001) handles up to 999,999 pages.
- Place the stamp in a bottom corner so it never covers exhibit text or existing page numbers.
- Keep one continuous Bates range across a document set rather than restarting per file.
- Export a Bates index so every document's first and last number can be verified later.

Need non-standard formats? See [custom Bates number formats](https://www.batesfast.com/blog/custom-bates-number-formats) for prefixes, suffixes, and template variables.
