A) According to Social Security website – You can view or update your contact information (e.g. change your address) of record via the My Profile Tab on my Social Security. In addition, you can decide when your change of address will take effect.
Who can update their address information online?
People receiving Social Security (Retirement, Survivors and Disability) benefits and those enrolled in Medicare can use my Social Security to change their address and other contact information.
This service is not currently available to people who also receive Supplemental Security Income (SSI) or do not have a U.S. mailing address. However, if you are receiving SSI, you can still check your address we have on record via the My Profile Tab on my Social Security.
