What is Bates numbering?
Bates numbering applies a unique sequential number to every page of a document set, commonly used in legal document production. Numbering here continues across all uploaded files in order.
Bates numbering stamps a unique sequential identifier on every page of a document set, so any page can be cited exactly. It is the standard way lawyers and investigators refer to pages in discovery. Here you set the prefix, the start number, the digit count, the separator, the position and the font size, then download the stamped file.
The prefix identifies the set, the start number sets where counting begins, and the digit count pads numbers with leading zeros so they sort correctly. The preview shows the first page, so check the position and size there before you stamp the whole set. Numbering continues across files in the order you add them.
Stamping adds a mark on top of each page. It does not change the page text, the page order, or the file structure. Because numbering continues across files, the order you add files is the order they are numbered, so arrange them first.
Can I number several files as one set?
Yes. Numbering continues across files in the order you add them.
What if numbering must start at a specific number?
Set the start number. The digit count controls zero padding, so 7 can print as 0007.
Does stamping change the original text?
No. It only adds the stamp on each page. The original content stays as it is.
