How to search for Nebraska business entities

The Nebraska Secretary of State offers a free Corporate & Business Search portal for looking up any registered entity in the state.

Navigate to the Nebraska Business Search portal and choose from five search methods:

• Name Starts With: returns names beginning with the words or letters entered (minimum three letters)

• Name Keyword Search: returns names containing the keywords entered; includes options to match all words or any of the words entered

• Name Sounds Like: phonetic matching for similar-sounding names

• Name Exact Match: requires the full entity name, including any corporate endings

• Account Number: searches by the SOS Account Number directly

Enter your business name, complete the reCAPTCHA verification, and submit your search. For precise results, use "Name Exact Match" with the full entity name including corporate endings; "Name Keyword Search" and "Name Starts With" support broader searches.

Click the "Details" button next to your entity name in the results to view complete information, including your SOS Account Number, formation date, Nebraska registered agent information, filing history, principal office address, and next report due date.

How to find your entity number in Nebraska

Your Nebraska entity number is a numeric identifier assigned by the Nebraska Secretary of State at formation. It appears as "Secretary of State Account Number" in search results and "SOS Account Number" on the entity details page. The SOS Business Services Division uses this number as the permanent identifier for all state filings and database searches.

Where to locate your Nebraska SOS Account Number

1. Nebraska business search (fastest method): displayed in search results and on the entity details page. The SOS does not publish a fixed digit count or pattern, so confirm your full number through the portal or your formation documents.

2. Certificate of Organization/Incorporation: usually at the top of the document, stamped by the Nebraska Secretary of State upon filing.

3. Biennial reports and state correspondence: appears on Nebraska SOS business documents and serves as your account identifier across all state filings.

How to find your entity type in Nebraska

Per the SOS Corporate & Business page, the database covers corporations (including professional corporations), LLCs, limited partnerships, and limited liability partnerships, along with trade names, trademarks, and service marks. General partnerships typically are not formed by filing with the SOS and do not have standalone entity records, though they may appear indirectly through a related LLP registration or trade name filing.

Where to find your Nebraska entity type

1. Nebraska business search (most accessible): clearly shown in search results under the "Type" column, listed as "LLC," "Corporation," "Limited Partnership," "LLP," etc.

2. Certificate of Organization/Incorporation: at the top of your formation document, using Nebraska's official entity type classifications. Cannot be changed without a formal amendment filing.

3. Nebraska biennial report filings: listed in the entity information section of every report.

Nebraska entity types at a glance

Common Nebraska SOS entity designations include Business Corporation, Benefit Corporation, Professional Corporation, Not-for-Profit Corporation, Limited Liability Company, Limited Partnership, Limited Liability Partnership, and Limited Cooperative Association. Nebraska's LLC statutes also recognize protected series as a sub-type of LLC. For the current list of recognized entity types and the statutes that govern each, see the SOS Select Corporation Statutes page.

How to find your formation date in Nebraska

Your formation date (when the Nebraska Secretary of State officially filed your business entity) appears on the entity detail page in the Corporate & Business Search and on your Certificate of Organization or Articles of Incorporation.

Where your Nebraska formation date appears

1. Nebraska business search (easiest access): listed as "Date Filed" on the entity details page, showing the official filing date with Nebraska.

2. Certificate of Organization/Incorporation: at the top of the document with the Nebraska Secretary of State filing stamp; may say "Filed on [date]" or "Date Filed: [date]" with the official state seal.

3. Biennial report confirmations: reference the original filing date. Nebraska sets biennial report due dates by entity type and filing date; check the SOS biennial reporting page or your entity's detail page for the next due date assigned by the SOS.

Formation date vs. effective date

Nebraska allows businesses to specify a future effective date when filing, creating two different dates:

• Formation date (file date): when the Nebraska Secretary of State processed your paperwork (use this one for compliance and onboarding purposes)

• Effective date: when your entity officially began operations, if you specified a later date

Under Neb. Rev. Stat. § 21-121, the general statute governing delivery and filing of records by the Secretary of State, a record may specify a delayed effective date up to 90 days after the filing date. This applies to both LLC and corporate filings, though most Nebraska entities have the same formation and effective dates.
