You can insert page numbers at the top or bottom of the page, and choose the position of the page number. You can also control the style of numbering, and the starting page number.
If your document already has a header or footer, see Add page numbers to a header or footer rather than using the steps below.
Insert and format a page number
On the Insert tab, click the Page Number icon, and then click Page Number.
In the Page Numbers dialog box, select a location, such as Bottom of page (Footer)) and then pick an alignment style. Word automatically numbers every page, except designated title pages.
To change the numbering style, in the Page Numbers dialog box, click Format and then choose the formatting you want to use.
Click OK twice to close both dialog boxes.
Remove page numbers
Caution: If you have headers or footers set up, using this option might remove them entirely. Instead, open the header or footer, select the page number, and then press Delete. You might need to temporarily move or resize any objects that are on top of the page number so you can select it.
On the Insert tab, click the Page Number icon, and then click Remove Page Numbers.
Page numbers can be formatted for each section individually. To change the format or style or start number for a section, put your cursor somewhere in that section, and then on the Insert tab, select the Page Number icon, and then select Format Page Numbers.
Sometimes when you work with page numbers, the header or footer area might stay open. To close the header or footer, on the Header & Footer tab, click Close Header and Footer, or double-click anywhere outside the header and footer area.
