Set up an online account at Social Security

• Note that you need an online account at Social Security to enroll in Medicare Part B. You do not have to retire or take Social Security income payments to have this account. If you have not already done so, please register for your Social Security Online Account on this link: ssa.gov/myaccount/create.html
• This account provides access to valuable information for you. For example, there is an annual report with estimated Social Security retirement payments at various ages. We can help you if needed.

Sign Up for Medicare Part B
