How to Bates Number Text Message Evidence: A Practical Guide

If you are preparing text message exhibits for civil litigation, arbitration, divorce discovery, or administrative hearings, your attorney or local court rules may require Bates numbering (also known as Bates stamping).

While legal teams use specialized enterprise e-discovery platforms to process corporate emails, self-represented litigants and individual plaintiffs frequently struggle to apply Bates stamps to personal iPhone text messages.

This guide explains what Bates numbering is, why legal proceedings require it, manual methods to number pages, and how TextDocket on Mac automates the process.

What Is Bates Numbering and Why Do Courts Require It?

Bates numbering is a standardized legal indexing system used in pretrial discovery and courtroom presentations. It assigns a unique, sequential identifier to each page of documentary evidence.

A typical Bates stamp consists of:

• An alphanumeric prefix identifying the producing party or exhibit (e.g., PLTF for Plaintiff, DEF for Defendant, or EXHIBIT-A).
• A sequential number, often padded with leading zeros (e.g., 0001, 0002).

Example: PLTF_0001, PLTF_0002, EXHIBIT-A-001.

Why Bates Numbering Matters in Litigation:

1. Precise Reference During Testimony: When examining a witness or arguing before a judge, attorneys must cite exact locations (e.g., "Please direct your attention to Exhibit A, page 14, lines 5 through 10"). Bates stamps eliminate ambiguity.
2. Preventing Missing Pages: Consecutive numbering makes it immediately obvious if a page was omitted or lost.
3. Compliance with Discovery Rules: Under civil discovery rules such as Federal Rules of Civil Procedure Rule 26 (General Provisions Governing Discovery) and Rule 34 (Producing Documents and Electronically Stored Information), parties are required to organize and label responsive documents to correspond with categories in the request.

Free Ways to Bates Number Text Message Records

If you have already created a PDF of your text messages, you can apply page numbers manually using built-in or free tools:

Method 1: Using macOS Preview / PDF Annotations (Manual)

1. Open your exported PDF in Preview on your Mac.
2. Select Tools > Annotate > Text.
3. Type your identifier (e.g., EXHIBIT-A-001) into a text box and drag it to the bottom-right corner of the page.
4. Repeat this step manually for every single page in the document.

• Drawback: Extremely tedious and prone to human numbering errors on documents longer than 10 pages.

Method 2: Printing and Using a Physical Bates Stamp Machine

1. Print your text message transcript onto physical paper.
2. Use an ink-based mechanical rotary numbering stamp to manually stamp the bottom corner of each sheet.
3. Scan the stamped physical papers back into a PDF.

• Drawback: Requires purchasing a physical stamp machine, consumes paper and ink, and degrades digital text clarity during scanning.

The Automated Solution: Native Bates Stamping with TextDocket

Instead of manually annotating PDFs or scanning physical pages, TextDocket applies clean, digital Bates numbering during the initial export process.

How to Apply Bates Numbering in TextDocket:

1. Open TextDocket on your Mac and choose your contact conversation.
2. Set your start and end dates.
3. In the export settings panel, enable Bates Numbering.
4. Enter your custom prefix (e.g., PLTF-MSG or EXHIBIT-1).
5. Set your starting number (e.g., 1 for 001).
6. Click Export PDF.

TextDocket automatically renders crisp, vector Bates identifiers and page counters (PLTF-MSG-001 - Page 1 of 28) across every page footer, perfectly aligned without overlapping any message bubbles or timestamps.

Best Practices for Bates Numbering Text Evidence

• Keep Prefixes Short and Consistent: Use simple prefixes like EXHIBIT-A or your last name so references remain clean.
• Pad Numbers with Leading Zeros: Using formats like 001 to 999 keeps file sorting orderly across file systems.
• Maintain a Master Index: If you produce multiple exhibits, keep an index tracking the date range, participants, and Bates range for each exhibit (e.g., Exhibit A: Texts between John and Jane (Jan 1 – Mar 15, 2026), Bates PLTF_0001 to PLTF_0042).
