Why a walk-in office
An in-person meeting helps when your situation has moving parts: a household with mixed coverage, self-employment income that changes, or a doctor you need to keep.
What to bring
Photo ID, Social Security numbers for everyone applying, a recent pay stub or income estimate, and a list of your doctors and prescriptions.
Before you call an agent
- Compare total yearly cost (premiums plus deductible), not just the monthly premium.
- Make a list of your doctors, hospitals and prescriptions before you call anyone.
- Check that the agent's license is active with the state regulator.
- Have a realistic estimate of next year's household income; subsidies are based on it.
Checking an agent's license in Missouri
- The Missouri Department of Commerce & Insurance offers a License & Contact Info search where consumers can check an agent's or agency's license. It also shows the agency an agent represents. Source

What if an office I visited won't renew my plan?
Any licensed agent certified with the marketplace can help you switch plans or renew at open enrollment.
Can I do everything by phone instead?
Yes. Licensed agents can quote, enroll and send documents electronically, which is how most people enroll today.
