About Bates Numbering

What is Bates Numbering? A legal document indexing system that assigns unique sequential identifiers to each page. Named after the Bates Automatic Numbering Machine patented in 1891.

Common Uses: Legal discovery, court filings, evidence tracking, document control, medical records, business contracts, and regulatory compliance.

Format Examples: CASE-001-000001, TRIAL-2024-000042-PAGE, DOC-000001-EX, SMITH-V-JONES-000123

Best Practices: Use consistent prefixes across related documents, maintain sequential numbering without gaps, and keep a master index of Bates ranges for each document set.
