Here are the steps to find the page ID in WordPress:

1. Access the WordPress Admin Section.
2. In the main WordPress menu on the left, click on Pages > All Pages.
3. If the page is recent, find it in the list. If not, use the search feature in the top right corner.
4. There are two ways to check page ID now:
- Check the URL in the address bar at the top of the browser window.
- Hover over the page title in the list and look at the link that appears at the bottom of your browser window. The link will show a URL with a post= parameter followed by a number. That number is your page ID.
