Step-by-step explanation:
Agents and brokers must enter their National Producer Number (NPN) on a marketplace application to receive compensation from Qualified Health Plan (QHP) issuers with which they have an appointment when assisting a consumer with that application.
The NPN is a unique identifier that allows the marketplace to verify the agent or broker's identity and track their activities to ensure they are properly compensated for the services provided to consumers.
