Iowa Business Entity Search

Check your name against Iowa law before you file. The state's search tells you whether a name exists. It does not tell you whether yours is legal, or whether it is too close to one already on the register. This does both.

What this does not check

  • • Whether the name is already taken. That needs the state’s live register, which we link below.
  • • Trademarks. A name can be free on the state register and still infringe a federal or common law mark.
  • • Domain and social handle availability.
  • • Whether the name is available in any other state you later register in.

Iowa LLC naming rules

Iowa Code § 489.112 and Iowa Code § 489.112(2), (4)

Your name must include one of

  • Limited Liability Company
  • Limited Company
  • L.L.C.
  • LLC
  • L.C.
  • LC
  • Ltd. Co.
  • Limited Co.
  • Ltd. Company

Your name must not

  • • Words that may only be used with the approval of another Iowa department or agency, unless you obtain that approval and file a record certifying it with the Secretary of State

When is a name too close to one already registered?

This is what catches most filings. Iowa compares your name against what is already on the register, and a difference that looks obvious to you may not count.

These do not make a name different

  • • Words, phrases or abbreviations indicating a type of person are not taken into account: corporation, corp., incorporated, Inc., professional corporation, P.C., professional association, P.A., Limited, Ltd., limited partnership, L.P., limited liability partnership, L.L.P., registered limited liability partnership, R.L.L.P., limited liability limited partnership, L.L.L.P., registered limited liability limited partnership, R.L.L.L.P., limited liability company, L.L.C., LLC, cooperative, coop or CP

These do

  • • The name must be distinguishable on the records of the Secretary of State from existing entities, limited liability partnerships whose statement of qualification is in effect, names people are registered to do business under, reserved and registered names, and fictitious names registered with the Secretary of State
  • • An administratively dissolved entity still blocks its name for five years from the effective date of dissolution, so a dead company is not a free name in Iowa

Names Iowa will accept with the other company's consent

  • • The holder of the conflicting name consents in a record and submits an undertaking, in a form satisfactory to the Secretary of State, to change their own name to one that is distinguishable

Our comparison cannot judge: Repeated or dropped letters. Texas treats "Texxas Strong" as the same name as "Texas Strong". Words that sound alike. Texas treats "Xpress Auto" as the same as "Express Auto". Words that mean the same thing in another language, where the state translates them. Anything the filing officer decides at their own discretion, which every state reserves.

Searching the official register

  • • The five year rule on administratively dissolved entities is the one to watch. A name can look free on the register and still be blocked
  • • We have not published a direct link to the business entity search because the Secretary of State’s site would not serve us when we checked, and we only publish a link once we have loaded it ourselves
