Medicare numbers can be found on Medicare cards and also on much of the correspondence from the Social Security Administration or the Medicare provider. Medicare numbers can also be obtained by visiting a local SSA office or by calling the Medicare provider and establishing the member's identity.
A Medicare number includes a person's social security number followed by a small code that consists of letters or letters with numbers depending on various factors. It is also called a Medicare claim number on documents from the provider. Because the number is primarily made up of a person's social security number, it is not easy to look it up if lost or forgotten.
