Add automatic page numbers to a Word document and control where they start.
It's in the Header & Footer group. A menu lets you choose where the number goes.
Choose Top of Page or Bottom of Page, then an alignment (left, center, right). Word inserts the number and opens the header/footer area.
With the header/footer open, check "Different First Page" on the Header & Footer Design tab. The first page's number disappears while the rest stay numbered.
Click Page Number > "Format Page Numbers" to start at a different number or use roman numerals. Click "Close Header and Footer" (or double-click the body) when finished.
