How to use it
Four steps
- 1
Set the prefix and start number
The prefix usually names the party or the file. The start number continues an existing set.
- 2
Choose the padding
Six digits is common. The tool warns you if your total will overflow it.
- 3
Paste your sources
One per line, as source name then page count, separated by a comma.
- 4
Copy the index
Take the table into your bundle, or export it as CSV.
Background
What the numbers mean
Why the index matters more than the stamps
When counsel asks what the examiner actually saw, the answer is the index, not the PDF. A source, a date, and a page range for every document is the difference between a five-minute answer and a day of a paralegal's time.
Common ways numbering goes wrong
The three that recur: a source added late and appended out of order, a page count taken from the PDF viewer rather than the document, and a padding width chosen before anyone knew the file would run past 100,000 pages. The tool flags the third and the first.
Nothing leaves your browser
You paste source names and page counts, not documents. Even so, remove identifying names before you paste. Use a description like 'GP clinical records' rather than a patient name.
FAQ
Questions people ask
What is Bates numbering?
A sequential number stamped on every page of a document set, so any page can be cited exactly. It is standard in litigation disclosure.
How many digits should I use?
Six digits covers 999,999 pages and is the common default. Use more only if you know the set will be larger.
Can I continue an existing set?
Yes. Set the start number to the next unused number and keep the same prefix and padding.
Does this stamp my PDFs?
No. It produces the ranges and the index. Stamping happens in your document software.
