29 C.F.R. § 570.121 Age certificates.
Title 29 - Labor
(a) To protect an employer from unwitting violation of the minimum age standards, it is provided in section 3(1)(2) of the Act that “oppressive child labor shall not be deemed to exist by virtue of the employment in any occupation of any person with respect to whom the employer shall have on file an unexpired certificate issued and held pursuant to regulations of the Secretary of Labor certifying that such person is above the oppressive child labor age.” An age certificate is a statement of a minor's age issued under regulations of the Secretary (Child Labor Regulation No. 1),31 31 Subpart A of this part. (b) It should be noted that the age certificate furnishes protection to the employer as provided by the act only if it shows the minor to be above the minimum age applicable thereunder to the occupation in which he is employed. Thus, a State certificate which shows a minor's age to be above the minimum required by State law for the occupation in which he is employed does not protect his employer for purposes of the Fair Labor Standards Act unless the age shown on such certificate is also above the minimum provided under that act for such occupation.
