What is PDF Bates Numbering?
Bates numbering (also called Bates stamping) is a standard way of assigning unique, sequential identifiers to pages in a document set. It is widely used in law firms, courts, compliance teams and corporate archives to keep track of large collections of PDFs.
With this online PDF Bates numbering tool, you can generate consistent stamps
like DOC-000123 or CASE-2025-001000-CONF across hundreds of pages.
The tool lets you control the prefix, starting number, number of digits and an optional suffix,
so your Bates numbers sort correctly and match your internal file standards.
How to Add Bates Numbers to a PDF
- Upload your PDF by clicking the upload box or dragging and dropping the file.
- Enter an optional prefix (for example, a case ID or project code).
- Set the starting number and digit length (e.g. 6 digits → 000123).
- Add an optional suffix for tags like “CONF” or “INT”.
- Choose the position on the page and adjust the font size.
- Click Generate Bates Numbers and wait for your stamped PDF to download.

Frequently Asked Questions
Is this Bates numbering tool really free?
Yes. The DevineTools PDF Bates numbering tool is free to use. There is no registration, subscription or watermark added to your files.
Are my legal documents uploaded or stored?
No. The tool uses a client-side PDF engine (PDF-lib) to process your file in the browser. The PDF never leaves your device, which is helpful for sensitive legal or compliance material.
How many pages can I Bates stamp?
The practical limit depends on your browser and device memory. For good performance we recommend keeping files under about 50 MB. Very large PDFs may take longer to process.
Can I control the number of digits?
Yes. The Number of digits setting lets you choose how many digits you want, for example 4, 6 or 8. The tool automatically pads numbers with zeros so they sort correctly in file systems and review platforms.
Can I change the Bates number style later?
Once a PDF has been stamped, you would need to run it through the tool again with different settings and replace the older copy. For that reason, it is a good idea to test a small sample document first and confirm the format with your team.
