Spotting Blogger post identification number is simple and same as what you did above to find out your blog ID. Go to posts from your Blogger blog dashboard and you will see all your posts. You can hover over the post title and you can see the post ID at the bottom corner, but few browsers won’t show the full URL. So open your post editor screen and check the URL in address bar where you will see your post ID. Your Blogger post will have a 19 digit identification number and you can see it next to your blog ID.
