What is Bates Numbering on a PDF?
Bates numbering (also known as Bates stamping) is an indexing method used in legal discovery and corporate compliance to assign unique, sequential reference identifiers to each page of a document packet. Commonly formatted with case-specific prefixes (such as CONFIDENTIAL-, PLTF-, or DEF-) and zero-padded digits (e.g., 000001), Bates stamping prevents document tampering and ensures precise page citation during trials, depositions, and regulatory audits.
Standard Legal Bates Numbering Formats
Depending on your jurisdiction and case role, Bates numbering uses standard convention codes to distinguish evidentiary sources:
| Prefix Type | Example Stamp | Standard Legal Application |
|---|---|---|
| Plaintiff Production | PLTF-000001 | Used by plaintiff counsel to number initial complaints and discovery exhibits. |
| Defendant Production | DEF-000001 | Used by defendant counsel during mandatory document disclosures. |
| Confidential Materials | CONFIDENTIAL-000001 | Protective order designations for sensitive financial records, PII, and trade secrets. |
| Deposition Exhibits | EXHIBIT-A-001 | Specific courtroom or arbitration evidentiary identification packets. |
Unlike legacy online PDF tools that upload sensitive litigation files to remote third-party servers, FileCraft processes document streams entirely inside your browser's local memory via WebAssembly. Your confidential client records, tax filings, and evidence packets never leave your machine—preserving strict attorney-client privilege.

Frequently Asked Questions
How do I Bates number a PDF for free?
Drag and drop your PDF into FileCraft, customize your prefix (e.g. CONFIDENTIAL-), set your starting number and digit padding (e.g. 6 digits), choose placement (such as bottom-right), and click Apply Bates Numbering. Your stamped document will be generated locally within seconds.
Will Bates stamping alter or blur existing PDF text?
No. Bates numbering is injected as an overlay on the PDF content stream with configurable margin padding, ensuring underlying text, signatures, and stamps remain fully legible.
Are there any file size or page count limits?
Because processing happens on your local device CPU rather than a shared cloud server, you can process large litigation binders with hundreds of pages without subscription fees or artificial limits.
