Medicare Part A and Part B
To check your Medicare Part A and Part B effective date, look at the lower right corner of your Medicare card. The effective date is also stated on the letter that you received from Social Security or the Railroad Retirement Board.
If neither of these items are available, call the Social Security Administration Monday through Friday from 7 AM to 7 PM at 1-800-772-1213 or 1-800-325-0778 (TTY Services).
The Railroad Retirement Board can be reached at 1-877-772-5772 or 1-800-325-0778 (TTY Services) Monday through Friday, from 9AM to 3:30PM.
Medicare Advantage or Medicare Part D Prescription Drug Plan
There is a wide range of coverage start dates for both Medicare Advantage and Medicare Part D depending on when you choose to enroll and which election period you use. For more information, contact your plan's administrator.
