Signing up for Medicare online is, far and away, the best and most efficient way to enroll in Medicare. When you about three months before turning 65 or leading up to retirement and enrolling in Medicare for the first time, it is time to get signed up for Medicare A and B. This is done through the Social Security Administration.
Signing up for Medicare online is done through Sign up for Medicare | SSA. Once you go there, you will have two options – signing up for both parts of “original” Medicare, Part A and Part B OR signing up for only Part B (if you already have Part A). You would start by selecting whichever of those options applies to your situation.
There are a few things that you would need to have and provide when you are signing up. Those are listed here:
Basic information about yourself

- Social Security number
- Where you were born (city, state, country)
Health insurance information
- Start and end dates for any current group health plans
- Start and end dates for any group health plans after age 65
For Part B only
- Valid email address
- Your existing Medicare number
Once you start the process of signing up for Medicare online, you will be prompted for various pieces of this information. Also, as a part of that process, you will be prompted to create a login for the ssa.gov website if you do not already have one.
The alternatives to signing up for Medicare online would be going to a local Social Security office. You can find a local office near you using this tool: Social Security Office Locator, SSA Office Locator Social Security Office Locator, Social Security. However, it is strongly recommended, both by Social Security themselves and by us, that you apply for Medicare online if possible. Long wait times and other inconveniences associated with visiting a Social Security office in person are long-documented. You can also call Social Security at 1-800-772-1213 as an alternative, although many tasks cannot be completed by phone.
Once you have enrolled in Medicare, you would need to decide whether you are going to stay with “original” Medicare and possibly get a Medigap plan or whether you are going to consider going with a Medicare Advantage plan. Either way, we are an independent brokerage that can help you compare all of your options in a centralized place.
