Frequently asked questions

What are Bates numbers?

Sequential reference numbers stamped on each page — traditionally used in legal discovery, medical records, and evidence to identify and cite pages uniquely.

How is the format controlled?

Set a prefix, a suffix, a starting number, and the digit width. For example, ABC-000001, ABC-000002, and so on.

Can I change the number position?

Yes — choose any of the six corners for the stamp.
