Ga. Code § 43-33-16
All licenses shall expire biennially unless renewed. All applications for renewal of a license shall be filed with the division director prior to the expiration date, accompanied by the biennial renewal fee prescribed by the board. A license which has expired for failure of the holder to renew may only be restored after application and payment of the prescribed restoration fee within the time period established by the division director and provided the applicant meets such requirements as the board may establish by rule. Any license which has not been restored within such period following its expiration may not be renewed, restored, or reissued thereafter. The holder of such a canceled license may apply for and obtain a valid license only upon compliance with all relevant requirements for issuance of a new license. The board shall require no less than four hours of continuing education in order to renew any license issued pursuant to this article.
