You can exclude the first page(s) from numbering. This may be needed if page 1 follows after pages that have no numbers, or have individual numbering as the table of contents in large books. To show number 1 on page 2, double-click on its page number field and set First page to 2. Note that to have the correct page numbers on the following pages, you need either place the page number field on a master page, or set the same First page value on all pages.
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
