The Independent Insurance Agents & Brokers of America (IIABA) is a national alliance of 300,000 business owners and their employees who offer all types of insurance and financial services products. Unlike company-employed agents, IIABA agents and brokers represent more than one insurance company, so they can offer clients a wider choice of auto, home, business, life, health and retirement products. IIABA agents and brokers not only advise clients about insurance, they recommend loss-prevention ideas that can cut costs. If a loss occurs, the independent agent or broker stands with the client until the claim is settled. IIABA was founded in 1896 as the National Local Association of Fire Insurance Agents. With the expansion of property-casualty business and coverages, the organization’s name was changed to the National Association of Insurance Agents in 1913. To emphasize its members’ ability to work with a variety of insurance companies, the organization became the Independent Insurance Agents of America in 1975. The Association’s name was changed in 2002 to the Independent Insurance Agents & Brokers of America to reflect the diversity of its membership, which includes both independent insurance agents and brokers. IIABA is a voluntary federation of state associations and local boards. Its independent insurance agents and brokers are politically astute and are involved both locally and nationally. They monitor and affect insurance agent and broker issues in Washington through IIABA’s active, professional staff on Capitol Hill. Their willing support has made IIABA’s political action committee-InsurPac-one of the largest federal trade association PACs in the nation.
