. I'm 30 years old, but I look so young that I get carded all the time.

What does it means to be carded?

to ask someone to show you a document, especially an identity card, in order to prove how old they are.

What happens when you get carded?

@MiltonG “to get carded” normally means to be asked for your identification card (ID or license). Usually it's used when someone is purchasing alcohol. “I was trying to buy beer, but I got carded.”
