In the US, corporate registration happens at the state level. The timeliness, availability, and licensing of this data varies among all 50 states. There is no federal dataset that contains all corporate registrations. It would be possible to create a unified open registry for all US corporations (even if only via aggregation from state ones) but this does not exist at this time.

Across those states performance varies widely and in many cases data is not available in bulk, is not machine readable, is not openly licensed etc. For more detail, see the per state summary on Open Corporates.

Reviewer comments

Good summary, I have no problem signing off on this. It's the best way of summing up a complex situation.
