If I been on DAC, should my Medicare has my mothers SS? It has my name and my mothers SS-C1 That is what it shows.?

A Medicare card shows a person's CLAIM NUMBER. Since you are drawing benefits off of your mother's account your claim number is her number followed by a C1, C2 or whatever. If there are several entitled children the youngest is C1, next youngest is C2, etc. Only if you were getting a social security benefit based upon your own earnings would it show your number.

If you look at any correspondence you receive regarding your DAC benefits you will notice that the claim # is on the letter. If you get SSI then the claim # is the person's own #.

Source: I was a social security claims rep for 32 yrs.

Never work. So I have no earnings. Was at the age of 21 then I got disable. So then the DAC all benefits should have my mothers SS?

Also is that correct? SSI TREAS 310 - XXSUPP SEC

Last month had also External Deposit - SSA TREAS 310 - XXSOC SEC but now is only the first.
