Find Iowa LLC & Corporation Records
This guide helps you use the official Iowa Secretary of State Business Entities Search to look up LLCs, corporations, nonprofits, business numbers, filing records, biennial reports, certificates, and forms.
Use it before you file through Fast Track Filing, verify a company, check a business number, order a certificate, file a biennial report, or decide whether an online record is enough for your next step.
Fast answer: Use the Iowa Secretary of State Business Entities Search to search by Business Name or Business Number. Business name search can use the first few letters or words of the business name. Business number search needs the complete business number.
Important legal note: Iowa’s SOS page says the office is a filing repository and does not represent or warrant the correctness or completeness of filing information. Use the record as an official filing reference, not as legal, tax, license, or fraud verification.
Best practical workflow: search business name broadly → open close matches → confirm entity type and status → save business number → review available filings → use Fast Track Filing, certificates, biennial reports, or forms only after confirming the exact record.

How to Search Iowa Business Records by Name or Business Number
The Iowa search page is simple, but the search type matters. Use business name for broad lookup and business number for exact lookup.
Open the official Iowa Business Entities Search page
Use the Iowa Secretary of State search page. Step 1 lets you choose Search by Business Name or Search by Business Number, and Step 2 lets you enter the matching information.
Open official search
Image description: this user-help visual reference shows the Iowa Business Entities Search screen where users can choose Search by Business Name or Search by Business Number and enter business name or business number details. It is not a claim that this website is the official state website.
Choose the right search type
Pick Search by Business Name when you know the name or only part of it. Pick Search by Business Number only when you have the complete number.
Start with fewer words
For name search, enter the strongest beginning letters or words. Remove LLC, Inc, Corporation, Company, commas, apostrophes, and punctuation if the first search fails.
Open close matches
Do not rely only on the first result. Open similar spellings, suffix variations, older names, and close matches before deciding which record is correct.
Save the business number
The business number is the cleanest way to return to the exact same record later. Save it before filing reports, ordering certificates, or contacting Business Services.
Review available filings
Check the entity status, filing history, registered agent details if available, and document images or records before you rely on the result.
Use Fast Track Filing only after confirming the record
For filings, reports, and many online actions, go through Fast Track Filing after confirming the exact business name and number.
How to Read an Iowa Business Record Without Making a Wrong Assumption
An Iowa SOS record is useful only when you understand what each field can and cannot prove.
Business name
Compare exact spelling, suffix, punctuation, and close variations. Similar names may belong to unrelated entities.
Business number
Save this number. It helps you return to the same record, file reports, request certificates, and contact the SOS office.
Entity type
LLC, profit corporation, nonprofit corporation, limited partnership, cooperative, and foreign entities have different filing rules and fees.
Status
Status helps you understand whether the record appears active, inactive, dissolved, revoked, or otherwise changed.
Filed records
Document images may be available, with sensitive information such as Social Security numbers redacted before public display.
Authority limits
The SOS does not determine the authority of a filer to submit a filing or whether information was authorized to be included.
Iowa Business Number Search When Exact Lookup Is Better
Business number search is best when you already have the official Iowa number from a record, filing, invoice, certificate, or report notice.
Use business number search when
- You have the complete number from an Iowa SOS record.
- You need to avoid similar-name confusion.
- You are preparing a biennial report.
- You are ordering certificate proof.
- You are contacting Business Services about one exact entity.
Do not confuse it with
- Federal EIN.
- Sales tax permit number.
- Invoice number.
- License number.
- Third-party website tracking number.
Fast Track Filing After You Confirm the Entity
Iowa directs many online business filings through Fast Track Filing. Search first so you do not file under the wrong record.
Online filing portal
Fast Track Filing is Iowa’s online filing portal for many business filings and report tasks.
Open Fast TrackConfirm entity first
Before filing a report, amendment, or certificate-related request, confirm the legal name and business number.

Certificates, Forms and Filing Follow-Up After Search

Certificate of Existence
Use certificate proof when a bank, lender, vendor, agency, or contract asks for official evidence of entity existence.
Start with searchForms and fees
