In India, insurance agents are licensed under rules set by the insurance regulator, IRDAI. Applicants generally need to meet a minimum age and education requirement, complete the prescribed training, and pass a pre-recruitment examination in life or general insurance, or both.
Licences are issued for a fixed period and must be renewed, so keeping your knowledge current is part of the job.
Requirements are updated from time to time. Always check the current rules with IRDAI or an authorised training institute before you apply.
