A single InDesign document can contain up to 9,999 pages, but page numbers can be as large as 999,999. (For example, you can correctly number a 100‑page document that starts on page 9,949.) By default, the first page is a recto (right) page numbered 1. Odd-numbered pages always appear on the right; if you use the Section Options command to change the first page number to an even number, the first page becomes a verso (left) page.
My quick process involves setting up a row of plaques with a01, a02, a03, thru a09. Then copy the plaques to the clipboard. Run the REPLACE TEXT feature to replace "a" with "1". Move row down and paste clipboard back into page. Run REPLACE TEXT to replace "a" with "2". Repeat until I get all the numbers. It's faster than manually typing the numbers in but I know there's go to be someway of automating the process. document numbering in publisher
