- Device & OS
- not provided
- 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 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.
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.
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'.
In the dialog box, set up your desired numbering format, including the number of digits, prefix, and suffix.
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.
Click 'OK' to apply the Bates numbering across the specified page range, then save your updated PDF file.

Use Standard Header & Footer with 'Add New' Option
If you don't require Bates numbering, you can use the standard page number tool and choose to add a new layer instead of replacing existing ones.
Add Page Numbers Easily with WPS Office
WPS PDF provides powerful, intuitive tools to insert page numbers, modify headers and footers, and combine PDF files effortlessly without losing your original formatting.
- 1. Open your PDF in WPS: Launch WPS Office and open your combined PDF file using the built-in WPS PDF tool.
- 2. Navigate to the Insert Tab: Click on the 'Insert' tab in the top navigation menu and select 'Page Number'.
- 3. Select Placement: Choose a position for the page numbers that avoids overlapping with your existing document headers and footers.
- 4. Apply Formatting: Adjust the font size and starting number, then click 'Insert' to apply the sequence to your combined document.

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.
