SOS Business Search

How to search Nebraska business entities online

Nebraska's business entity search is at nebraska.gov/sos/corp/corpsearch.cgi, operated by the Nebraska Secretary of State's Corporate Division. The portal uses a legacy CGI-based interface and requires a reCAPTCHA completion before each search. No account is needed to search; filing requires a separate eDelivery account.

Updated August 2026

reCAPTCHA required, and name availability isn't checked through the search

Nebraska's search portal requires completing a reCAPTCHA before each search, which blocks automated or scripted lookups. Separately, the portal is not a formal name availability tool — a name appearing or not appearing in results is not an official determination. To check name availability, you must submit a written request by email, fax, or mail to the Corporate Division.

What the search covers

The database covers all entities registered with the Secretary of State: domestic and foreign business corporations, professional corporations, Nebraska Benefit Corporations, nonprofit corporations, LLCs, professional service LLCs, limited partnerships, limited cooperative associations, LLPs, trade names, trademarks, and service marks.

Search modes

Five name-based modes are available along with an account number lookup:

  • Name Starts With — begins-with match
  • Keyword — All Words — every word you enter must appear
  • Keyword — Any Word — at least one word matches
  • Name Sounds Like — phonetic/Soundex matching
  • Name Exact Match — requires the full legal name
  • Account Number — the Nebraska Secretary of State entity account number

Name availability — a separate process

Nebraska does not provide name availability determinations through the public search portal. To check whether a specific name is available for registration, you must submit a written request by email to sos.corp@nebraska.gov, by fax to (402) 471-3666, or by mail to the Corporate Division. A name appearing or not appearing in search results is not a formal name availability determination.

Accessing filed documents and certificates

Filed documents and Certificates with Seal (Nebraska's equivalent of a Certificate of Good Standing) can be ordered through the authenticated subscriber portal at nebraska.gov/sos/ccorp. New entity formations and other document filings go through the eDelivery system at nebraska.gov/apps-sos-edocs.
