What the Iowa data holds

The data is the Iowa Secretary of State's "Active Iowa Business Entities" list on data.iowa.gov (CC BY 4.0). It covers LLCs, PLLCs, corporations, nonprofit corporations, limited partnerships and LLPs, domestic and foreign.

Only active entities are served: an entity that leaves the list is no longer served. The list is published monthly and read weekly.

The official search is run by the Iowa Secretary of State. Sources as at 6 Nov 2026.

The Iowa number: IA- plus the register number

An Iowa company number is IA- and the register number: IA-253951 is Iowa Holdings, L.L.C. Only the shape is verified, there is no check digit. A name works as well: type it and pick the match.

The address is the home-office address, null where the register has none.

What is not served

General partnerships, unincorporated non-profit associations, farm trusts and authorities are never served. There are no officers, and registered agents (names and addresses) are never read.

In code

The same search as a request with an API key. The response has the same shape as every country the API covers.
