The US has no national ID and for historical ideological reasons the pushes for a national ID fail.
That's why social security numbers are abused as a form of national ID number. The closest thing we have is the "Real ID" standard for state IDs/driver's licenses (well, ignoring passports). [1]
So right now government solutions are done individually by states (if at all), usually as some form of "wallet" / "mDL" (mobile driver's license) phone app.
All the state ID databases are supposed to be able to talk to each other, eventually, so maybe some day a big state's system will allow verifying IDs from other states but there might be political issues that block that.
I guess the other option is that a big state's system (like say California's OpenCred[2]) gets popular enough for all the other states to implement it. But I'm not hopeful.
