Iowa business name search

Before you fall in love with a name, make sure it's free in Iowa. The only authoritative source is the state's own registry — here's the direct link, plus Iowa's LLC naming rules and what an "available" name does and doesn't get you.

Official state registry

Search the Iowa Secretary of State

This is the official government database for Iowa — free to search, and the single source of truth for whether a name is taken.

How to check Iowa name availability

  1. 1 Open the Iowa Secretary of State business search (linked above) — it's the official, free, authoritative registry.
  2. 2 Search your exact name, then variations (singular/plural, with and without "the", different designators).
  3. 3 An entity that already exists with a confusingly similar name means yours is likely unavailable — the name must be "distinguishable upon the record".
  4. 4 If it's clear, forming in Iowa costs about $50 in state fees for year one — reserve the name or file your Articles of Organization to lock it in.

Iowa LLC naming rules

Required designator

Every Iowa LLC's legal name must end in a limited-liability designator. Accepted forms include:

LLCL.L.C.Limited Liability Company

Distinguishability

Your name must be distinguishable upon the record from every entity already on file in Iowa. Tiny tweaks usually don't count — swapping "Inc." for "LLC", adding "the", or changing punctuation won't make a near-identical name acceptable.

Restricted & barred words

Words implying a bank, trust, insurance, or a regulated profession (e.g. “Bank”, “Insurance”, “Engineering”) usually need approval from the relevant state agency. Words suggesting a government agency (e.g. “FBI”, “Treasury”) are barred.

Reserving the name

Name reservation is available for 120 days.

Available ≠ yours to own

A clear Iowa entity search means the name is free to register as a business in Iowa. It does not give you a trademark — those are national, based on real use in commerce, and a business in another state could already own the brand. Before you print cards or buy a domain, run a free trademark search too.

Name's clear — ready to form in Iowa?

Forming an LLC in Iowa runs about $50 in state fees for year one. You can file directly with the state yourself, or use a formation service to handle the paperwork and act as your registered agent.

Frequently asked questions

How do I check if a business name is available in Iowa?

Use the Iowa Secretary of State business-entity search — the official state registry — and look up your proposed name. Iowa requires a new LLC name to be "distinguishable upon the record" from every existing entity, so search variations, not just the exact string. It's free and authoritative; third-party "name check" sites just query this same database.

What words must a Iowa LLC name include?

Your legal name must contain a limited-liability designator. In Iowa, accepted forms include: LLC, L.L.C., Limited Liability Company. Words implying a bank, trust, insurance, or a regulated profession (e.g. “Bank”, “Insurance”, “Engineering”) usually need approval from the relevant state agency. Words suggesting a government agency (e.g. “FBI”, “Treasury”) are barred.

Does an available name in Iowa mean I own the trademark?

No. A clear Iowa entity search only means no other Iowa business is registered under that name. It does NOT grant trademark rights, which are national and based on use in commerce. Before you commit to a brand, also run a free trademark search — see our trademark-search tool.

Can I reserve a name in Iowa before forming?

Name reservation is available for 120 days.
