If your Medicare card is lost or damaged, you can order a new card at www.socialsecurity.gov on the web. Or, call Social Security at 1-800-772-1213. TTY users should call 1-800-325-0778. If you get benefits from the Railroad Retirement Board (RRB), call your local RRB office or 1-800-808-0772, or visit www.rrb.gov on the web and select "Benefit Online Services."
Your card may be slightly different. It's still valid.
