Bates numbering for discovery, done on your own machine

Bates numbers are unique, sequential labels stamped on every page of a document production, with a prefix, zero-padding and no gaps or restarts across batches. Filozy applies them locally, with a start value so the next batch continues where the last one stopped.

Every page produced in litigation gets a name it will keep for the life of the case: ACME-000417. When a deposition refers to it, a brief cites it, or a judge asks for it, that label is how everyone finds the same page. That is Bates numbering, and it has rules that ordinary page numbering does not.

The rules

Break continuity — restart at 1 for a new batch, skip a range, produce a duplicate — and the production is challenged. The rules exist because the labels are evidence.

Doing it on your own machine

Discovery documents are, by definition, the ones with the highest stakes for confidentiality: privileged communications, personal data, trade secrets. Uploading them to a stamping website means a third party holds an unredacted copy of a production, however briefly.

Header, footer & Bates numbers applies the stamps inside your browser. The document is read into memory, the labels are drawn into each page’s content, and the result is saved locally — nothing is transmitted.

What the tool gives you

Two constraints worth knowing: the stamp is set in a standard font whose encoding covers Latin text, so prefixes should use plain letters and digits; and the stamp is placed relative to the visible page area, so on a scan whose page box starts off the corner the margin is measured from where the page actually shows.

Step by step for a scanned production

  1. Prepare the scans. Auto crop removes scanner borders so the stamp lands in a clean margin.
  2. OCR with OCR PDF if the production must be searchable — most protocols require it.
  3. Open Header, footer & Bates numbers. Set the prefix, the padding width, and the start value (1 for the first batch; the previous last number plus one for any later batch).
  4. Choose the position — bottom right is conventional — and a page range if any pages are excluded.
  5. Preview the first, a middle and the last page. Confirm the number sequence reads correctly and does not overlap content.
  6. Save. Record the range — first and last number, and the batch — in your production log.
  7. Protect PDF if the production is delivered encrypted, or Flatten first if it carries annotations.

The Prepare a scanned contract for filing workflow runs this sequence — trim, recognise, number, protect — passing the file between tools without re-selecting it.

Questions people ask

Bates numbers or page numbers?

Different things. Page numbers restart with each document and describe position within it. Bates numbers run across an entire production — every page of every document, in order, never restarting — and identify a page uniquely for the rest of the case. A page can carry both.

How do I continue numbering in a second batch?

Note the last number of the previous batch and enter the next one as the start value. If batch one ended at ACME-000482, batch two starts at ACME-000483. Keep a log of ranges per batch; opposing counsel will ask.

Can I use a non-English prefix?

Stick to Latin letters, digits and basic punctuation. The stamp is set in a standard PDF font whose encoding covers those; characters outside it — Japanese, Arabic, some accented letters — come out as question marks.
