We don't automatically include page numbers on the PDF.
But you can use your own PDF editing tool to add if you need them.
e.g. In Adobe Acrobat:
1. Launch Adobe Acrobat and open the file into which you want to add page numbers.
2. Click “Tools” on the main menu in Acrobat and click “Pages.” Select “Header & Footer” on the Pages submenu and click “Add Header & Footer.” In Acrobat for Mac, click “Document” on the main menu, hover your mouse over “Header & Footer” and click
If you don't have Adobe Acrobat there are free tools online like https://www.ilovepdf.com/add_pdf_page_number that also allow you to add them.
