Final answer:
Brokers must notify the Commission of a change of company address within the period specified by their respective financial or securities commission's regulations, which varies by jurisdiction.
Step-by-step explanation:
The requirement for a broker to notify the Commission of a change of company address typically falls under regulations set forth by the relevant financial or securities commission. Such notifications are important for maintaining up-to-date records and ensuring compliance with legal and regulatory standards, though the specific number of days within which a broker must report this change can vary depending on the regulatory body and jurisdiction.
For example, the Financial Industry Regulatory Authority (FINRA) in the United States requires brokers to update their address within 30 days of the change. It is critical for brokers to consult their respective regulatory agency's rules to determine the precise notification period required. In a broader context, changing an address may also require updates to voter registration or through the Department of Motor Vehicles, depending on the state.
