I was due for a renewal in late August but I renewed in last week (I’m turning 21 at the end of this month!) The only thing is that if you get it renewed BEFORE you’re 21, the “Under 21” text will still be there. It doesn’t matter how close to your birthday you renew, if it’s before, then the text will be there. You can still use the license to by drinks though, just make sure they look at the birthdate.
