Official Health Insurance Marketplace Phone Number and Hours
The primary Health Insurance Marketplace customer service number is:
1-800-318-2596 (TTY: 1-855-889-4325)
This line connects you to the federal Marketplace (HealthCare.gov) or your state’s Marketplace if you’re in a state that uses the federal platform. Hours of operation vary depending on the season:
| Time Period | Hours (Eastern Time) |
|---|---|
| Open Enrollment (Nov 1 – Jan 15) | 24 hours a day, 7 days a week |
| Special Enrollment Period | 8 a.m. – 8 p.m., Monday–Friday |
| Outside Open Enrollment | 8 a.m. – 8 p.m., Monday–Friday |
During peak open enrollment weeks, you may experience longer wait times. Calling early in the morning (right at 8 a.m. ET) or later in the evening often reduces hold times.
If you need after-hours help outside of open enrollment, the automated system can handle password resets and basic account questions. For complex issues, plan to call during the windows above.
