Kendall Jenner ﻿got lucky when she was turned away from a 21 and over event at Coachella -- she didn't bother trying to flash a fake ID because everyone knows she's underage -- but hundreds of other teenage scofflaws were humiliated in a series of fake ID seizures.

Festival security busted 354 IDs presented by kids who wanted to score drinks with the help of phony IDs. Although technically it's a crime to flash one, no one really gets prosecuted.

The bogus IDs are actually put to good use. They're sent to the California Dept. of Alcoholic Beverage Control so investigators can eyeball state of the art counterfeit documents.
