How to find post, page, tag, category and media ID in WordPress
It should be so simple: Add a column to the post, page, category and tag overviews displaying each item’s ID. I’m sure the WordPress development team is aware of this omission, but for some reaso they have chosen not to implement it. The fact remains that webdesigners and administrators need to look up the ID’s of these items regularly, especially when developing or customizing themes. Or when you need to create redirections after a permalink settings change. There are numerous occasions where I have had a need for them.
