If you’re a self-taught InDesign user, you may not have been introduced to automatic page numbering, one of the biggest time-saving features in the program. InDesign allows you to set up the page numbering feature in your Master Pages. Then, as you add or shuffle pages, InDesign updates individual page numbers accordingly. You can style the page number any way you like.
Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
