How to add page number in word from 3rd page?

Of course, this is a classic Word puzzle! The key is to use a Section Break. This tells the software that your document has different parts.

First, go to the very end of your second page. Navigate to the ‘Layout’ tab. Click on ‘Breaks’ and then select ‘Next Page’. This creates a new section that starts on your third page.

Now, double-click in the footer (or header) of page 3. You must disable the ‘Link to Previous’ button in the menu. This step is essential! Once it is unlinked, you can go to ‘Page Number’ and insert your number. You can even format it to start counting from ‘1’. The first two pages will remain completely blank. Voilà
