Article 4 - Employment of Minors
135 - Duties of Employers.

(ii) As used in this subdivision, the term "establishment" includes a
factory, mercantile establishment, business office, restaurant, hotel,
and any other trade, business or service.
2. The employer of any person claiming to be between eighteen and
twenty-five years of age who does not present an employment certificate
duly issued for him or her must require from such person, and furnish
upon demand to the commissioner or his or her authorized representative,
proof of the age of such person in the form of a driver's license or
other documentation issued by the government of the United States or of
any state located therein, or a certificate of age issued to such person
by an employment certificating official. Such proof of age or a legible
photocopy thereof, or an employment certificate, previously issued for
such person and on file in the place of his or her employment, shall be
conclusive evidence that the person has reached the age certified to
therein.
