I'm unable to follow the only guide available from Adobe as it doesn't seem to apply to Adobe Acrobat DC. Here is a highlight from the support article which I will link below, there is no "More" option in the secondary toolbar under the "Edit PDF" tool utility. Can anyone explain how to add bates numbering to documents in Acrobat Standard DC?
When designating documents for Bates numbering, you can add PDFs, and any non-PDF files that can be converted to PDF. The process converts non-PDF file types to PDF, and then adds Bates numbers to the resulting PDF.
Look at the link. You can add bates numbers with Acrobat Pro.
I found it under "Stamp"
