How to Check If an LLC Name Is Available in Iowa

The short answer

Short answer: Iowa's official search is the Secretary of State's Business Entities Search at sos.iowa.gov. It is free and needs no login. The trap: a name can belong to a company that no longer exists and still be blocked — Iowa protects an administratively dissolved company's name for five years after dissolution, and the search only matches names that begin with what you type.

The official search

The registry is run by the Iowa Secretary of State, Business Services division.

The database covers over 600,000 entities, active and inactive — corporations, LLCs, partnerships, and other Secretary of State filers, plus reserved, registered, and fictitious names. It does not cover sole proprietors or partnerships trading under a name recorded only with a county recorder.

There is no separate "name availability" tool that gives a yes or no. You judge availability from the search results, and the Secretary of State makes the final decision when your Certificate of Organization or name reservation is reviewed — a reservation is granted only if the Secretary finds the name available.

A results list shows the business number, name, status, and name type. Clicking the business number opens the detail record, drawn from the filing information the state holds — addresses, previous names, agents, and filing history. The name-type code — legal, former, fictitious, reserved, or registered — matters, because any of those types can block you.

Step by step

  1. Open the Business Entities Search and choose Search by Business Name. The other mode, Search by Business Number, is only useful if you already know a company's state number.
  2. Enter the first few letters or words of your name, without "LLC." This is a begins-with search: typing "NOW" returns NOW INC., NOWHERE INC., and NOW PUBLICATIONS INC. Typing a word from the middle of your name will not find a company that starts with something else.
  3. Shorten your entry to widen the net. A shorter beginning catches more near-matches. Run the search again on the first word alone, and on any alternative opening words you are considering.
  4. Open every close match and check its status and name type. An active company blocks you, obviously — but so does an administratively dissolved one, for five years after dissolution. Reserved, registered, and fictitious names count too.
  5. Remember what the search strips out. The system removes noise words such as "THE" and "AN" from the front and words like "CORPORATION" and "INC" from the end, so do not rely on those words to make your name different.
  6. If nothing conflicting appears, the name is probably available — but only the Secretary of State's review of your filing is definitive. Searches return at most 1,000 results, so a common opening word may need a second word added.

Iowa's name rules

The rules are in Iowa Code §489.112 of the Iowa Uniform Limited Liability Company Act.

Designator. The name must contain "limited liability company" or "limited company," or the abbreviation "L.L.C.," "LLC," "L.C.," or "LC." "Limited" may be shortened to "Ltd." and "company" to "Co."

Distinguishable. The name must be distinguishable on the records of the Secretary of State from:

  1. The name of an existing entity on file — including one that has been administratively dissolved, for five years after the dissolution takes effect
  2. The name of a limited liability partnership whose statement of qualification is in effect
  3. The name under which a person is registered to do business in Iowa
  4. A name reserved under §489.113
  5. A name registered under §489.114
  6. A name registered with the Secretary of State as a fictitious name

Differences that do not count. Words and abbreviations that only indicate the type of entity — "corporation," "corp.," "incorporated," "Inc.," "Limited," "Ltd.," "limited partnership," "limited liability company," "LLC," "cooperative," and similar terms — are not taken into account. Changing only the ending, from Inc. to LLC for example, does not make a name distinguishable. With the other holder's consent in the form the statute requires, or a court judgment establishing your right to the name, an otherwise blocked name can sometimes be used.

Reserving a name. Iowa allows name reservations under §489.113: $10 for 120 days of exclusive use, filed with the Secretary of State. A reservation is optional — it does not form an LLC — and it can be transferred to another person by a signed notice, also $10.

What the search can't tell you

If the name looks available

File a Certificate of Organization — Iowa does not call it Articles of Organization — with the Secretary of State, online through the separate Fast Track Filing system at filings.sos.iowa.gov (an account is required there), or by mail or in person.

Ongoing: the biennial report.

FAQ

Is the Iowa LLC name search free? Yes. The Business Entities Search is free and requires no login. Only filing documents — through the separate Fast Track Filing system — requires an account.

Why didn't my search find a company I know exists? Probably the search mode. Iowa's name search only matches names that begin with what you typed, so search on the opening letters or words of the company's name, not a word from the middle.

Can I use the name of a dissolved Iowa company? Not right away if it was administratively dissolved. Under Iowa Code §489.112, that name stays unavailable for five years after the dissolution takes effect.

How much does it cost to form an Iowa LLC? The Certificate of Organization filing fee is $50. Reserving a name first is optional and costs $10 for 120 days.

When is the Iowa LLC biennial report due? Between January 1 and April 1 of odd-numbered years. It costs $30 online or $45 on paper, and going more than 60 days past due lets the state start administrative dissolution.
