I got a call today saying that there was something wrong with my medical insurance card and I wanted to stop using it. The number is 12333.

You must pay attention to this kind of phone call, which is generally deceptive. Because there is such a software, you can change the display when making a phone call, and you can display any number you want. Generally, the social security bureau will not call you, so it generally ignores it. I really don't trust. You can go to the Social Security Bureau to check your account online. But remember not to be credulous.
