How to Check If an LLC Name Is Available in Oregon

The short answer

Short answer: Oregon's official check is the Secretary of State's Business Name Search, and its Business Name Availability Check method is free with no login. The trap: Oregon's standard is so lenient that a single letter's difference can make a name "distinguishable" — so passing the state check is easy, but it tells you almost nothing about whether you can safely use the name, and the availability check only scans active businesses.

The official search

The registry is run by the Oregon Secretary of State, Corporation Division, through the Oregon Business Registry.

The database covers corporations, LLCs, limited partnerships, LLPs, business trusts, and assumed business names (ABNs) — Oregon's version of a DBA — registered with the Corporation Division.

Oregon gives you two layers of checking. The Business Name Availability Check compares the main words in your name against active businesses on file and suggests whether the name can be registered. The regular search methods return the actual matching records for you to judge. Either way, the Secretary of State is clear that the final determination is made at the time of filing — the search is a strong signal, not a ruling.

A results list shows the entity type, entity status, registry number, name status, and business name for each match, and the detail record shows the entity's registration information, including its registered agent and addresses. One warning from the state itself: its records do not include every business using a given name — a business that has not registered yet simply does not appear.

Step by step

  1. Open the Business Name Search from the Secretary of State's name-availability page and type your proposed name, without worrying about "LLC" — entity designators don't affect the result.
  2. Run the Business Name Availability Check first. This is the state's own availability method. If it suggests the name can be registered, keep going — don't stop here.
  3. Run "Exact words in any word order." This finds records containing your words in any order, combined with any other words.
  4. Run a Soundalike search. Oregon offers "Soundalike words" in exact or any word order, which catches names that are spelled differently but sound the same.
  5. Run the Extended search. This is the broadest pass — it also pulls in words with similar meanings or sounds. If a conflict exists anywhere in the registry, this is the search most likely to surface it.
  6. Check the assumed business names carefully. ABNs sit in the same database, and they count against you if they are of active record — but they are filed by county, so an identical ABN registered in a different county is a different situation from one in yours.
  7. If nothing close appears, the name is probably available — subject to the Corporation Division's review when you file.

Oregon's name rules

The rules are in ORS 63.094 of the Oregon LLC Act, with the Secretary of State's name-availability guidance explaining how distinguishability works in practice.

Designator. The name must contain "limited liability company" or the abbreviation "L.L.C." or "LLC." A low-profit LLC uses "L3C" instead.

Distinguishable — and Oregon's bar is low. The name must be distinguishable upon the Secretary of State's records from every other active LLC, corporation, professional and nonprofit corporation, cooperative, limited partnership, business trust, reserved name, registered corporate name, and assumed business name. But the state explains the standard this way: a name is distinguishable if it does not exactly copy a name already on record, and a word — or even a single letter's difference — can be enough. Different key words, key words in a different order, creative spelling, or a number written a different way (5 vs. Five vs. V) all count.

Differences that do not count. Changing only the entity word ("Inc.," "LLC," "Co.," "Corp."), punctuation or special characters, spacing, or capitalization does not distinguish a name. Neither does adding an "s" to make a word plural, singular, or possessive, or adding/removing words like "a," "an," "and," "at," "by," "for," "in," "plus," "the," "to," and "with."

Prohibited terms. An Oregon LLC name may not contain "cooperative," "corporation," "corp.," "incorporated," "Inc.," "limited partnership," "L.P.," "LP," "Ltd.," "limited liability partnership," "L.L.P.," or "LLP." The ban on "Ltd." catches people out — it is part of the legal designator in some other states and flatly forbidden here.

Characters. English letters, Arabic or Roman numerals, and incidental punctuation only.

Reserving a name. Oregon law (ORS 63.097) lets you reserve a name for 120 days if you are not ready to file. The reservation fee is reported as $100, matching Oregon's other $100 filings — confirm the current amount on the Corporation Division's fee schedule before you send anything, and skip the reservation entirely if you are ready to form now.

What the search can't tell you

If the name looks available

File Articles of Organization with the Corporation Division, online through the Oregon Business Registry or on the paper form.

Ongoing: the annual report.

Note the separate clock if you also register an assumed business name: an ABN costs $50 and renews every two years, not annually.

FAQ

Is the Oregon LLC name search free? Yes. The Business Name Search, including the Business Name Availability Check, is free and requires no login. You only need an account when you go on to file.

How different does my name have to be from an existing Oregon business? Not very. Oregon accepts a name if it does not exactly copy an active record — a different key word, a different word order, creative spelling, or even a single letter's difference can be enough. Changes to punctuation, spacing, capitalization, plurals, or the "LLC/Inc." designator do not count.

Can an assumed business name (ABN) block my Oregon LLC name? Yes, if it is of active record — assumed business names are part of the distinguishability test. But ABNs are filed by county, so identical ABNs can legitimately exist in different counties.

How much does it cost to form an Oregon LLC? The Articles of Organization filing fee is $100. The annual report is another $100 every year, due on your filing anniversary.

If the state accepts my name, does that mean I own it? No. Acceptance means the name is distinguishable on the Secretary of State's records. Your right to use the name comes from actually using it in business and from trademark law — the state gives its own warning example of registering a Starbucks-like name and still being sued.
