To sign up for a health plan under the Affordable Care Act (Obamacare), start by going online to learn about what's available and how much it will cost. If your state has set up its own online health insurance marketplace (exchange), start there. If your state doesn't have its own site, you'll use the federal exchange.
Most health insurance marketplace websites work great and can easily take you through the application process from start to finish. You can also get your health insurance questions answered over the phone or in person. Select your state from the list on this page to find out the options where you live.
