At what age do you not need to bring ID to buy alcohol?

I think i may have phrased my title wrong but the law states that no store can sell alcohol to anyone under the age of 21 years old. I see a sign on 7/11 that says if you look under 27, you need to have ID with you. I just turned 21 and when i bought alcohol i showed ID because i hate paying and them asking for ID. I take ID and cash out before i get to the register.

I know that if you look old enough then you probably dont need but at what age did you guys not need to bring ID to buy alcohol? I know the law requires the store and bar owners to enforce it very strictly. Of course your appearance would count a lot too.

Do any of you guys who are 25 and up still get carded to buy alcohol sometimes? I am 21 and my face looks around there but I might even look younger to most people. I am asian by the way. Are there any of you guys who are underage or around 21 22 but never have been asked for ID when you were buying alcohol?
