> US still doesn't have a national-wide internal ID, and for the thing what essentially replaced it in function - driver's ID, every state has it's own format and idea what should be in it.

One of the nation-wide IDs actively in use is the tuple (state, driver_license_number).

Which means John Doe, DOB 11/12/1975, 6'12'' (OH, 123456) and John Doe, DOB 11/12/1975, 6'12'' (FL, 123456) are two different people!

Each identifier identifies a person. A person may have multiple identifiers. I have a non-US nationally-unique drivers license ID and a passport number.
