Private by design. This tool runs entirely in your browser — your file is processed on your device and is never uploaded to us. How this works

Bates Numbering stamps a unique, sequential identifier on every page — like ABC-000001, ABC-000002 and so on. It’s the standard way legal, accounting and eDiscovery teams label documents so any page can be referred to unambiguously across a case or an audit.

The numbering is applied in your browser, so sensitive case files never leave your device — free, private, no account and no watermark. Set a prefix and a starting number, and Ream stamps the rest in order.

How it works

ABC-000001 ABC-000002 ABC-000003 sequential, one per page

Ream adds a bold identifier to the bottom-right of each page: your prefix followed by a zero-padded number that increases by one per page, starting from the number you choose. Because it stamps in order, you can carry on from where a previous batch left off simply by setting the start number.

What is Bates numbering?

ABC-000001 ABC-000002 ABC-000003

Named after the Bates automatic numbering machine, Bates numbering gives every page in a set a unique, sequential label. In litigation and eDiscovery it makes documents citable and traceable — a lawyer can point to “ABC-000142” and everyone knows the exact page. A consistent prefix identifies the producing party or matter; the running number keeps order.

Working across batches

  • Use a prefix that identifies the case, party or set (e.g. SMITH-).
  • To continue a sequence, set the start number to one past where the last file ended.
  • Bates numbers are permanent once printed — if a document also needs sensitive parts hidden, redact it first, then stamp.
