§ 3218. Evidence of age. 1. Evidence showing that the minor is of the
required age shall be presented as follows:

a. A duly certified transcript of a birth certificate filed according
to law, or duly certified transcript of a record of baptism, giving the
date of birth; or, if not available,

b. A passport showing the date of birth of the minor; or, if not
available,

c. Other documentary evidence or other recorded evidence in existence
two years or more, and satisfactory to the certificating officer, except
an affidavit of age.

2. Certificate of age. A person over eighteen years of age may apply
for a certificate of age to the superintendent of schools, the district
superintendent, or to the certificating officer. Upon such application a
certificate of age, containing the name, date of birth, address and
signature of the applicant, shall be issued to him if he furnishes such
evidence that he is over eighteen years of age as is required for the
issuance of an employment certificate. Such a certificate of age or an
employment certificate previously issued for such person shall be
conclusive evidence for an employer that the person has reached the age
certified to therein.
