Okla. Admin. Code § 310:210-5-1
A barber or instructor license shall only be issued to an individual who passes the required examination or meets the requirements for a reciprocal barber license as outlined in 310:210-5-9 of this chapter, and pays the appropriate licensing fee established by the Board. No person shall practice any phase of barbering for fee or otherwise who does not have a current valid barber, barber apprentice, graduate-apprentice, or instructor license, and a photo ID in their possession. A duplicate license shall be issued if the licensee submits a notarized statement as to its loss, except that an instructor upon a written request shall be issued a duplicate license as a barber without fee for use in a barber shop. The barber license number shall be the same as the instructor license.
