InDesign numbers pages consecutively when you add a page number marker to your document's master pages. You can change the appearance of these page numbers and control when the numbering restarts ...

Any InDesign user can still open and edit your document; clients can even add pages to the document, but only at the page specified when you initially set up the document.
