The unified number shall be included in the automated systems in the actual environment (direct work) only after conducting the necessary tests in a test work environment, after reviewing all risks and safety means, ensuring that those risks are closed, and after obtaining approval from the relevant work unit to move to the actual environment as per the policies approved in this regard. The unified number shall be closely monitored after its application in the actual environment and the necessary measures shall be taken if the financial entity is affected. This excludes some financial institutions (other than banks, finance, and insurance) whose work does not require application in a test work environment (depending on the nature of their activities, automated systems, number of customers, and methods of dealing).
