What is Bates numbering and why do I need it?

Bates numbering is a sequential page-identification system used in legal, medical, and business settings. Each page receives a unique identifier (typically a prefix plus a sequential number, like 'SMITH-000001'). Courts and regulatory bodies require Bates numbering during litigation discovery, patent filings, and compliance audits to ensure every page can be precisely referenced and verified. Without Bates numbers, opposing counsel or regulators may challenge the completeness of your document production.

Can I set a custom starting number for continuation across document sets?

Yes. You can specify any starting number, so if your previous batch ended at SMITH-000450, you can start the next batch at SMITH-000451. This is essential for multi-volume discovery productions where numbering must be continuous across hundreds of documents.

Will Bates numbering affect the original content of my PDF?

The Bates stamps are added as an overlay in the header or footer margins of each page. Your original document content, formatting, and layout remain completely untouched. The stamps can be placed in any of six positions to avoid overlapping with existing headers or footers.

Is this secure enough for privileged legal documents?

Absolutely. Unlike cloud-based Bates numbering services that require uploading sensitive case files to remote servers, our tool processes everything locally in your browser using WebAssembly. Attorney-client privileged documents, work product, and confidential evidence never leave your computer. There is no server transmission, no cloud storage, and no third-party access.
