How to: Bates Numbering
- Select one or more PDFs in order.
- Set prefix, start number, digits and position.
- Click Start and download.
Bates numbering gives every page in a set of documents a unique, sequential identifier, such as ABC000001 – a standard in litigation, discovery and compliance work. Because Fileopia runs locally, privileged and confidential documents are never sent to a third-party server.
Common uses
- Number documents for legal discovery or disclosure.
- Label pages of evidence bundles and exhibits.
- Track pages in audit, insurance or compliance submissions.
Tips for best results
- Choose enough digits for the whole production (6 digits covers up to 999,999 pages).
- Order files correctly before starting; numbering continues from one file to the next.
- Use a matter-specific prefix to avoid confusion between cases.
Bates number format
A typical Bates number combines a prefix (often a case or party code), a zero-padded sequence and optional suffix, for example SMITH-000123. Positioning in the bottom-right corner is a common convention.
