Maine business entities & Secretary of State workflows

Corporate search and related services

Search by name or charter number for status, filings, and paid certificates or copies when offered. Card or InforME may be required; read each screen before you pay.

  • Many entities must file an annual report by June 1; confirm your type and year on the official annual report flow from the hub.

File annual reports and other corporate filings

UCC information

Financing statements & lien search

UCC search and electronic filing

Open UCC Search or UCC Filing, then choose card or subscriber login. Filings need debtor, secured party, and collateral details. Maine uses exact debtor-name rules (suffix words count); odd characters may become spaces with a review step before submit. The page shows how current the index is.

Tips if the site feels confusing

  • ICRS and UCC use different Maine.gov applications; empty corporate search does not mean there are no UCC filings, and the reverse is also true.
  • Maine applies exact debtor-name rules for UCC search (organizational suffix words are not ignored); read the on-screen guidance before you treat a search as clear.
  • Questions about UCC Search and Filing: (207) 624-7752 or CEC.Corporations@informe.org as listed on the official UCC page.
