What is Bates numbering?
Bates numbering is a method of indexing legal documents with a unique, sequential identifier on every page. It is named after the Bates Automatic Numbering-Machine, a hand stamp patented in the 1890s. A typical Bates number combines a prefix identifying the party or case (SMITH, ACME-PROD), a fixed-width number padded with zeros (000001), and sometimes a suffix such as -CONF for confidential material. Because the sequence continues across the entire production, a Bates number identifies not just a page but its exact place in everything exchanged. That is why order matters: add files in the order they should be produced. Courts and opposing counsel usually expect the stamp in the lower-right corner, clear of existing content — the PDFWix default.
