Table of Contents

In legal practice and commercial litigation, preparing thousands of pages of discovery documents requires a reliable, court-accepted identification system. Bates numbering assigns unique alphanumeric codes to every page, ensuring attorneys, judges, and opposing counsel can cite specific evidence without ambiguity.

#11. The Structure of a Standard Bates Identifier

A compliant Bates number consists of three primary components:

1. Prefix: A short alphanumeric code identifying the case or producing party (e.g. `CASE-` or `DEF-EX-`).

2. Padded Number: A sequential numeral with fixed zero-padding (typically 6 digits, such as `000001` through `000250`) to maintain uniform character width.

3. Suffix (Optional): Additional exhibit identifiers or confidentiality classifications (e.g. `-CONF`).

  • Bottom-Right Anchor: The most universally accepted court position, placed at least 0.5 inches inside the page margin.
  • Uniform Sizing: 10pt or 12pt monospaced or sans-serif typography ensures instant legibility on electronic discovery portals.
  • Sequential Continuity: Missing or skipped numbers trigger evidentiary objections, making deterministic numbering essential.

#22. Privacy in Discovery: Why Local Stamping Matters

Uploading sensitive corporate discovery files, trade secrets, or unredacted medical evidence to commercial web converters risks severe ethical and confidentiality violations.

Frequently Asked Questions

Can I customize the starting number offset?

Yes, set any starting integer (e.g. start at 1001 for Exhibit B) to maintain continuity across multiple production batches.

Does Bates stamping overwrite existing page text?

Bates numbers are placed in standard margin safe-zones. You can select between top-right, bottom-right, or bottom-center to avoid existing footers.
