How to Automatically Create Multiple Numbered PDFs in Acrobat
Question details
The user needs to automatically generate 50 separate copies of a three-page PDF, with each copy featuring a unique serial number repeated on every page.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Batch creating customized PDF copies with sequential serial numbers for distribution or record-keeping.
- Observed behavior
- Manual duplication and numbering is inefficient and prone to errors, requiring an automated batch processing workflow.
Ensure you have Adobe Acrobat Pro installed, as standard versions may not include the Action Wizard or advanced Bates Numbering features required for automated batch processing.
Automate Serial Numbering using Acrobat Action Wizard and Bates Numbering
Utilize Acrobat's built-in Bates Numbering combined with the Action Wizard to automatically stamp unique serial numbers across multiple PDF copies.
Bates numbering is specifically designed to add sequential numbers to PDF pages. By combining this feature with the Action Wizard, you can automate the process across numerous duplicate files without manual editing.
First, duplicate your original three-page PDF 50 times in a dedicated folder using your operating system's file manager.
Open Adobe Acrobat Pro, navigate to the 'Tools' menu, and select 'Action Wizard'.
Click 'New Action'. Under 'Files to be Processed', add the folder containing your 50 PDF copies.
From the 'Choose tools to add' panel, select 'Pages' > 'Bates Numbering' > 'Add', and click the '+' icon to add it to your action steps. Uncheck 'Prompt User' so it runs automatically.
Specify the Bates Numbering options, such as the number of digits, starting number, and position on the page (e.g., top right corner).
Save the action, then run it. Acrobat will process all 50 files in the folder, applying sequential numbering across every page of every document.

Use a Custom Action or Stamping Script
If standard Bates numbering does not meet specific formatting requirements, a custom dynamic stamp or third-party action script can be used to apply file-specific numbers.
Add Sequential Numbers Easily with WPS PDF
WPS Office provides robust PDF editing tools, including Bates Numbering and header/footer customization, allowing you to easily index and add sequential serial numbers to your PDF documents.
- 1. Open your PDF: Launch WPS Office and open your source PDF document.
- 2. Access Bates Numbers: Navigate to the 'Insert' or 'Edit' tab on the top ribbon and locate the 'Bates Numbers' tool.
- 3. Add and configure: Select 'Add Bates Numbers'. In the dialog box, configure your numbering format, prefix, and starting number.
- 4. Apply to pages: Set the page range to apply the numbering to all pages, then click 'OK' to stamp the document.

Frequently Asked Questions
What is Bates Numbering in PDFs?
Bates numbering is an indexing method used primarily in legal, medical, and business fields to assign unique, sequential alphanumeric identifiers to every page of a document or set of documents.
Can I use standard Adobe Acrobat to batch add serial numbers?
Batch processing features like the Action Wizard are typically restricted to Adobe Acrobat Pro. Standard versions generally only allow you to apply Bates Numbering to one file or a manual selection of files at a time.
Why is the sequential numbering not applying to every page?
Ensure your Bates Numbering settings are configured correctly. Check the page range options in the setup dialogue to guarantee it is set to apply to 'All Pages' rather than just the first page.
