You can choose to have the page numbers shown in your header or footer start with a value other than 1.
For example, if the document you’re working on follows another document or file in a larger collection of printed pages, you might want numbering in your current document to start with a later page number.
Tip: You can also choose to start page numbering later in your document. For example, if the first page is a cover page and the second page is a table of contents, you might want the third page to show “Page 1.” To learn how to do that, see Start page numbering later in your document.
To start page numbers with something other than 1, follow these steps.
Double-click in the header or footer area of a page in your document.
Word opens the header or footer for editing and displays the Header & Footer tab.
If your document does not already have page numbers, click Page Number in the Header & Footer tab, and then click Page Number.
Word displays Page Numbers, where you can select the position and alignment of page numbers, and then click OK to add them to your document.
Click Page Number > Format Page Numbers.
In the Page Number Format dialog box, select Start at, and then type the number you want as the starting page number for the document.
To stop editing the header or footer, click Close Header and Footer, or double-click anywhere outside the header or footer area.
