Finding Post ID in 3.3

If you go to your admin panel, and go to either posts or pages (depending on which one you need to find), and hover (don’t click) over each post/page and look toward the bottom left of right of your browser window, you will see a link.

Near the end of the link you will see something like pageID= followed by a number. That’s the ID of that post/page.

Alternatively, there are a few plugins out there which will add a column to your admin panel displaying the ID of every post or page. My plugin, Ultimate Tinymce will do this for you.
