How can you tell if someone is lying about their age?

What access to information, are you in person, online only?

Ask them year specific questions
Make up a year and say "oh you're a '92 as well" or something like that
Check their ID

Generally hard. But look at their hands skin and neck skin. Makeup and genetics can disguise many things but hand skin and neck skin... no

What if the range is still 20-30? Young-looking but can't say if 18 or 28.

Ask the school they went to, ask for record, year book, etc.

Ask them what the first movie they remember watching? Or child hood movies, if you really want to be a scumbag just jack their wallet or get their personal info and run background checks and do detective work interviewing the family etc.

-Ask what was the first movie they saw in theaters
-ask when their first voting season was
-look at pictures of them as a kid (hairstyles, popular toys, camera quality, style of furniture)
-if you have them on Facebook, look at their Friends; the most common age group could be their ballpark age
