Age verifiers post the user info to a thread in a private area of the forum. Every so often (usually 7-10 days), one of the admins goes through the list and makes the updates.
So yeah, 4 days since verification is nothing. It could take up to another week.
EDIT: I just checked. Your info was submitted 2 days ago by Defcon 1. The last batch update was about a week ago, so you'll more than likely have access in the next few days.
