Do you need a valid id to get into Las Vegas Nevada?

Answer 1

No, there's no guards at the city limits checking identification.

Perhaps you mean do you need a valid ID to drink or gamble in Las Vegas, and the answer is yes, unless you look like you're self-evidently over 21.

Underage children are allowed to walk through casinos when accompanied by parents, but anyone who looks like they might possibly be under 21 can expect to find security checking their IDs in short order if they attempt to gamble or even if they pause for very long when walking through a gambling area.

The gaming commission takes this pretty seriously, so most casinos do also. It doesn't matter if your parents are right there with you or not, you are not allowed to loiter in a gaming area if you're under 21.

Answer 2

Yes, absolutely.
