How Do You Get a Replacement Medicare Card?

Online

You can also request a replacement Medicare card through Social Security at ssa.gov. Log in to your account and select the “Replacement Documents” tab. Then select “Mail my replacement Medicare Card.” 

Telephone

Call Medicare at 800-MEDICARE (633-4227), or Social Security at 800-772-1213, to get a new card. The best times to call are during off-peak hours, in midmorning or midafternoon. Try not to call first thing in the morning, during lunch hours or late Friday afternoons. 

In person

Visit your local Social Security office to get a replacement card. Check ahead to see what days and times the office is open. 

Did you get your new Medicare card?

All Medicare beneficiaries were supposed to get new cards by April 2019 featuring a randomly generated Medicare Beneficiary Identifier (MBI),2 This card uses numbers and letters, instead of a Social Security number.  This is meant to prevent identity theft. If you still haven’t gotten one, request a replacement card. Medicare recommends that you destroy the old card with your Social Security number on it when your new one arrives.

What if You’re New to Medicare? 

That depends on your enrollment status.

There are certain situations that result in automatic Medicare enrollment. Examples include those turning 65 who are already receiving Social Security retirement benefits and those under 65 who have been receiving Social Security disability insurance (SSDI) benefits for 24 months. These individuals will receive their Medicare cards in the mail about two to three months before the effective date. 

Those who are not enrolled automatically must take action to enroll in Medicare. These Medicare cards will arrive about 15 to 30 days after enrolling. 

If you are requesting a replacement, this card will also arrive within a month after the request. If you need your new Medicare card more quickly, you can request a temporary letter as proof of membership, which you should receive in about 10 days. Or, you can visit the mymedicare.gov site and print a temporary card.
