If you’ve ever been involved in litigation or document-heavy cases, chances are you’ve heard the term Bates stamp or Bates numbering. But what exactly does it mean—and why is it such a vital tool in legal document management?
In this article, we’ll break down what Bates stamping is, why it matters, and how to use it effectively in your legal practice.
What Is a Bates Stamp?
A Bates stamp (also known as Bates numbering or Bates labeling) is a method of applying sequential identifiers—usually numbers or a combination of letters and numbers—to individual pages within a set of documents.
Each page receives a unique number (e.g., AMATA_000001, AMATA_000002, and so on), making it easier to:
- Track documents
- Refer to specific pages during legal proceedings
- Organize discovery materials
- Prevent accidental duplication or omission
The process was originally done using a mechanical stamping machine created by Edwin G. Bates in the late 1800s. Today, Bates numbering is typically applied using document management software, scanners, or specialized legal tools like Adobe Acrobat, LexisNexis, or CaseMap.
Why Bates Stamping Matters in Legal Practice
In legal proceedings, clarity and organization are everything. Bates stamping helps ensure that your documentation is:
- Traceable – Each page has a unique identifier, so nothing gets lost or misfiled
- Citable – You can reference specific pages in pleadings, depositions, or hearings
- Auditable – Courts, opposing counsel, and clients can follow the document trail
- Compliant – Bates stamping is often required in discovery protocols and court rules
Whether you’re managing discovery, preparing exhibits, or producing documents under subpoena, Bates numbers make your document set cleaner, more professional, and easier to defend.
When to Use Bates Stamping
You should consider using Bates stamping anytime you’re working with large volumes of legal documents, especially when sharing materials with opposing counsel or the court.
Common use cases include:
- Civil litigation and eDiscovery
- Document productions during discovery
- Exhibits for depositions or trials
- Case file organization
- Legal audits or compliance reviews
At Amata, our paralegal and administrative support teams regularly help clients apply Bates stamps for document productions—whether it’s physical documents being scanned and stamped or electronic files needing consistent page numbering.
Best Practices for Bates Numbering
To get the most out of Bates stamping, keep these best practices in mind:
- Prefix your identifiers (e.g., SMITH_000123) to associate documents with a client, case, or party
- Don’t skip or reuse numbers—this can cause confusion or call document authenticity into question
- Stamp both hard and digital copies for consistency
- Use secure, court-compliant tools that log timestamps and user actions
- Include a Bates reference table if producing complex document sets
