Bates numbering assigns unique sequential identifiers to legal documents so every page or file in a production can be precisely cited and located. Hintyr supports document-level and page-level numbering with configurable format, position, and typography.
What is Bates numbering
Bates numbering is the legal industry standard for stamping each page or document in a matter with a unique sequential identifier. The term comes from the Bates Automatic Numbering Machine, a mechanical device once used to imprint consecutive numbers on paper documents. Today the process is digital, but the purpose remains the same: create a permanent, unambiguous reference system for every item in a document collection.
A typical Bates number has an optional prefix, a zero-padded numeric sequence, and an optional suffix. For example, DOC_00001-PRIV contains the prefix "DOC_", the padded number "00001", and the suffix "-PRIV". This format ensures numbers sort correctly and stay readable in production logs, deposition transcripts, and court filings.
Document-level vs page-level Bates numbering
Hintyr offers two numbering modes. In document mode, each file gets a single Bates number regardless of page count. A 50-page contract and a 1-page letter each get one number. This mode works well for early case assessment, internal reviews, or matters where page-level citation isn't needed.
In page mode, every page of every document gets its own sequential number. A 10-page PDF receives 10 consecutive numbers, one per page. This is the standard for most litigation productions and regulatory submissions because it lets counsel cite a specific page with certainty. Page mode is the default in Hintyr.
Ways to apply Bates stamps
Hintyr provides several ways to apply Bates numbers, each suited to a different stage of your workflow:
- Automatic - Turn on auto-numbering in case settings so every new upload gets a Bates stamp immediately. Learn more in automatic numbering.
- Manual - Select files from the document browser, open the file menu, and choose Bates Number. A dialog lets you configure all options before stamping. See manual numbering.
- During export - Apply Bates stamps as part of your production export. Your original files stay unmodified. See export with Bates.
- AI agent - Use natural language commands to apply Bates numbering to all files or filtered subsets. See AI Bates numbering.
Why Bates numbers matter in litigation
Without Bates numbers, referencing a specific page in a large document collection means writing something like "page 47 of the contract attached as Exhibit B to the Jones deposition." With Bates numbers, the same page is simply "ABC000047." Every party, the court, and the record can use that reference without ambiguity. This consistency reduces confusion, prevents citation errors, and is often required by court rules governing document production under FRCP Rule 34(b)(2)(E) and local discovery orders.
Bates numbers also serve as an audit trail. If a party disputes whether a particular page was included in a production, the Bates sequence provides a verifiable record. Hintyr's gap detection feature goes further by identifying missing or duplicate entries in the sequence.
