After enrolling in Original Medicare Part A and Part B, but before signing up for a specific plan, you will need to gather the following information:
- ZIP code
- Medicare number
- Medicare effective dates
- Last name
- Date of birth
- Bank account or credit card information (If you need to pay for a premium)
If you do not yet have your Medicare ID card, call the Social Security Administration, 1-800-772-1213 or 1-800-325-0778 (TTY). A representative should be able to tell you the Medicare effective dates.
