They are but some clerks are extra suspicious. When I was 24 (coincidentally!) I thought I definitely looked 20-something, but I walked into a liquor store and tried to buy some vodka and the clerk took my real, legitimate ID, squinted at it, accused me of not being the person depicted on the ID, held it under the UV light that reveals the marks that are supposed to make it hard to counterfeit, squinted at it some more, took it in the back and started making a phone call…

I thought she was going to call the cops on me, but eventually she came back and sold me the booze.

I read your comment, thought “Am I dealing with one?” and had to reach into my shirt to check if it had one or not. It turns out it does! So… I guess so. I’m irregular in other ways, though, so I might not be a good point of comparison.
