Scenario
Combining multiple PDF documents from various sources into one file and needing sequential pagination across the whole document.
Observed behavior
The goal is to append new page numbers as a separate layer or distinct element so that original headers and footers remain intact.
Before you start

Before adding new page numbers, ensure you have finalized combining your PDF documents and have saved a backup copy of the original file in case the formatting overlaps.

Solution 1Recommended

Use Bates Numbering in Adobe Acrobat Pro

Bates numbering allows you to add sequential page numbers as a separate layer, ensuring it doesn't interfere with existing headers and footers.

Bates numbering is specifically designed to add indexing to legal, medical, and business documents without modifying the original content. It acts as an overlay rather than replacing existing header and footer metadata.

1
Open the Bates Numbering Tool

Open your combined PDF in Adobe Acrobat Pro. Navigate to 'Tools', select 'Edit PDF', click on 'More' in the secondary toolbar, and choose 'Bates Numbering' > 'Add'.

2
Configure Numbering Format

In the dialog box, set up your desired numbering format, including the number of digits, prefix, and suffix.

3
Select Placement

Click into one of the header or footer text boxes where you want the number to appear. Ensure this location does not share the same physical space as the text in your existing headers.

4
Apply and Save

Click 'OK' to apply the Bates numbering across the specified page range, then save your updated PDF file.

Frequently Asked Questions

Can I adjust the starting page number when combining multiple PDFs?

Yes, most professional PDF editors, including Adobe Acrobat and WPS PDF, allow you to specify the starting number and the specific page range when applying page numbers.

What is Bates numbering used for?

Bates numbering is an indexing method used primarily in the legal and medical fields to assign unique, sequential identification numbers to each page of a document without altering or replacing the original text.

Why are my new page numbers overlapping with existing headers?

This happens when the placement settings for the new page numbers use the same margins as the original headers. You can fix this by adjusting the margin settings or selecting a completely different location (like the bottom corner) for the new numbers.

Is it possible to remove page numbers later if I make a mistake?

Yes. If you used Bates numbering or the standard Header & Footer tool, you can go back to the same menu in your PDF editor and select the 'Remove' option to clear the newly added sequence.
