Exactly. When we discuss “national ID” we are talking about an identification document: a tool that allows authenticating a person; an SSN doesn’t do that. It is an identifier, not an identification document.
(We do have a actual national IDs, but they aren’t universal or mandatory, either in theory or in practice, though they are required for certain purposes and will be soon for more, and are increasingly common. Passports, state-issued IDs meeting REAL ID standards, Enhanced Driver’s Licenses, etc.)
