Search by name (the system automatically strips words like "The" and "Inc.") or entity number, then open the Business Entity Summary to see the registered agent, officers, and filed documents free. The database covers domestic and foreign LLCs, profit corporations, nonprofit corporations, limited partnerships, limited liability partnerships, cooperative associations, and unincorporated nonprofit associations.

Searching by name

Iowa's name search has a few behaviors worth knowing before you start. The system automatically strips common leading words — "THE," "AN" — and trailing designators like "CORPORATION" or "INC" before matching. Searching for "AN ORIGINAL DESIGN INC." and "ORIGINAL DESIGN" will reach the same records. Results are listed alphabetically up to a cap of 1,000 matches; if you exceed that cap, narrow the search by adding more of the name.

A "Modified?" flag in results means the entity's legal name contains special characters that can't be typed in a standard search field — a tilde, a degree symbol, or similar. These are displayed in the system only, not in the search input.

Searching by entity number

Every entity receives a unique numeric ID from the Iowa SOS at the time of formation or registration. Entering that number directly in the search field bypasses the 1,000-result cap and returns the single matching record. Numbers should be entered without formatting — digits only.

Entity detail page

The Business Entity Summary for each record includes the entity number, all registered name types (legal name, reserved names, fictitious names, foreign fictitious names, former names — 15 name-type codes are defined under Iowa Code), the entity type and applicable Iowa Code chapter, formation date, current status, registered agent name and address, officer and director information, and links to all filed document images. Social Security Numbers are redacted from all document images before they are published online.

Frequently Asked Questions

Why does searching 'AN ORIGINAL DESIGN INC.' find the same result as 'ORIGINAL DESIGN' in Iowa?

Iowa's system automatically strips common leading words like 'THE' and 'AN,' plus trailing designators like 'CORPORATION' or 'INC,' before matching names. So both searches reach the same record.

What does the 'Modified?' flag mean in Iowa business search results?

It flags that the entity's legal name contains special characters that can't be typed in a standard search field, such as a tilde or degree symbol. These display in the system only, not in the search input itself.

How many businesses are in Iowa's database, and is there a limit on search results?

Iowa's database holds records for more than 600,000 active and inactive entities. Name search results are capped at 1,000 matches, listed alphabetically; entering the entity's unique numeric ID bypasses that cap and returns a single record.
