Do you get to keep a check if the person dies after the 20th of the month

I need to change my deposit account number

The check received each month is for the previous month, for Social Security and the current month for SSI. For Social Security checks, the person had to be alive every day for the month of entitlement, which would be the previous month. For SSI, the beneficiary is entitled for the month they receive the check, even if they die the same month.

I don't know. Call Social security
