About Bates Numbering

What Is Bates Numbering?

Bates numbering is a method of indexing legal documents for identification and retrieval. Each page gets a unique sequential identifier — typically a prefix, a zero-padded number, and optionally a suffix. The standard format looks something like ABC000001 or CASE-001234-EX.

OxygenPDF stamps Bates numbers directly onto your PDF pages. You configure the prefix, suffix, starting number, digit count, position, font size, and margin. Everything runs in your browser.

Who Uses Bates Numbering

Bates numbering is a requirement in legal proceedings and regulated industries where every page of every document must be uniquely identifiable.

Litigation & Discovery

Court rules require Bates-stamped documents for discovery productions. Every page gets a unique number so attorneys can reference specific pages in motions and depositions.

Regulatory Compliance

Government agencies and regulators expect sequentially numbered pages in submissions. Bates numbers create an audit trail.

Document Management

Large document sets become navigable with Bates numbers. Each page has a permanent reference that doesn’t change if documents are reorganized.

Archival & Records

Medical records, financial audits, and insurance claims benefit from Bates numbering for traceability and cross-referencing.

Configuration Options

Prefix and suffix are optional text that bookend the number. Digit count controls zero-padding — set it to 6 and page 1 becomes 000001. The start number lets you continue a sequence from a previous document.

Nine position options place the Bates number wherever it’s needed. Font size and margin are adjustable. The preview updates in real time as you change settings.

How It Compares

Bates numbering is primarily a legal tool. Most PDF editors treat it as a premium feature.
