About This Tool
Bates numbering (or Bates stamping) is the standard method used in legal discovery, litigation, and trial preparation to uniquely identify every page of evidence and documentary production. A standard Bates stamp consists of an alphanumeric party identifier or exhibit prefix followed by a zero-padded sequential serial number (commonly 6 to 8 digits).
### Tool Implementation and Capabilities The interactive tool on this page provides an instant client-side format and sequence previewer. It allows paralegals, litigation support specialists, and attorneys to test custom case prefixes (such as PLAINTIFF-, DEF-EXHIBIT-, or SEC-PROD-) and starting page numbers to verify zero-padding formatting before applying stamps in discovery production software. Note that this tool does not upload or modify PDF files directly; it generates and previews the exact Bates identification string format in your browser.
### Worked Example A legal team is preparing responsive documents for Defendant ACME Corp in federal litigation:
- **Prefix:** DEF-ACME- - **Starting Number:** 145 - **Formatted Output:** The generator produces DEF-ACME-000145 using 6-digit zero padding. - **Subsequent Pages:** In a 50-page production batch, stamps will run sequentially from DEF-ACME-000145 through DEF-ACME-000194.
### Client-Side Privacy Note This previewer operates entirely within your browser local JavaScript environment. No document identifiers, case prefixes, or evidentiary numbers are transmitted across any network or recorded on our servers.
How to Use
- 1
Type your designated party or production prefix into the Prefix field (for example, PLAINTIFF- or EXHIBIT-).
- 2
Enter your initial document page sequence number in the Starting Number input.
- 3
Review the live 6-digit zero-padded stamp preview generated immediately below the controls.
- 4
Copy the verified formatting string into your case management or PDF production numbering template.
Frequently Asked Questions
What is the standard digit length for Bates numbering?
Most legal discovery protocols and court rules require 6 to 8 zero-padded numeric digits (such as 000001 through 000999 for 6 digits) to maintain consistent column alignment in discovery indices and production logs.
Does this tool burn Bates stamps directly into uploaded PDF documents?
No. This tool is an interactive sequence and prefix preview utility. It runs in your browser to verify stamp formatting without requiring document uploads. For actual document stamping, use dedicated PDF redaction and production software with the tested prefix.
Is my case or client prefix tracked or sent to a server?
No. The tool runs purely client-side via React state. No inputs, prefixes, or sequence values are ever uploaded or stored.
