The Series 6, also referred to as the Investment Company and Variable Contracts Products Representative Qualification Exam, allows individuals to sell mutual funds, variable annuities, variable life insurance, unit investment trusts (UITs), and municipal fund securities. To obtain the Series 6 license, first, you must pass the Securities Industry Essentials (SIE) exam, and then obtain sponsorship from a FINRA member firm or a self-regulatory organization to take the Series 6 exam. The Series 6 is often seen as the ideal companion license for those in the insurance industry.
