How do I get a new Medicare card if my card is lost, stolen, or damaged?

Beneficiaries may now request a replacement red, white, and blue Medicare card online on Social Security's web site. The card will be mailed within thirty days to the address SSA has on record. If a beneficiary is unable to use the online request to obtain a replacement Medicare card, he or she may call Social Security's toll-free number, 1-800-772-1213 or visit a local field office.
