Each Marketplace application has a unique identification number, or Application ID. After you apply for Marketplace coverage, you’ll get a notice with your eligibility results that contains your Application ID. You’ll need your Application ID to continue with an existing application, compare plans, and complete enrollment. If you are doing this by phone, you can provide your Application ID to the Marketplace Call Center representative so they can find your application faster. If you’re continuing your application, comparing plans, and enrolling online, you’ll be asked to enter your Application ID after you log in to your account and select “Find my existing application.”
