How to Add Bates Numbering to PDF Documents

Bates numbering (also called Bates stamping) is the practice of assigning sequential numbers, letters, or date labels to each page of a document set. It is widely used in legal discovery, medical records management, contract administration, and any industry that needs to index large volumes of pages. Adding Bates numbers manually is tedious — a dedicated tool automates the process in seconds.

Why Use Bates Numbering?

• Legal discovery — Numbered pages make it easy to reference exhibits and depositions
• Document indexing — Every page gets a unique identifier for filing and retrieval
• Contract management — Track versions and amendments by sequential page labels
• Medical records — Maintain page order and audit trails in patient files
• Compliance — Meet regulatory requirements for tamper-evident page numbering

Bates Numbering Options

A good Bates numbering tool lets you control every aspect of the label:

• Prefix — Add a text prefix like DEF- or EXH-A-
• Suffix — Append text after the number, e.g. -v1
• Start number — Begin from any number, not just 1
• Digit padding — Zero-pad to 3, 4, 5, or 6 digits for consistent alignment
• Position — Place the label at any corner or centered at the bottom

Example output: DEF-00001-v1, DEF-00002-v1, DEF-00003-v1 across all pages.
