Data Sources

Maine uses a single integration against the Maine Secretary of State, Division of Corporations, UCC & Commissions via the public Information Corporate Registry System (ICRS) at apps3.web.maine.gov/nei-sos-icrs/ICRS. This is the official online register for business corporations, limited liability companies, limited partnerships, limited liability partnerships, and nonprofit corporations registered in Maine, covering both domestic entities and foreign entities qualified to do business in the state.

Maine SoS ICRS (verification, primary). Every request reads live against the register. The Information Summary returns legal name, charter number, filing type, status, filing or qualification date, jurisdiction, assumed and former names, the principal home office address, and the clerk or registered agent name and address.

Maine does not publish a free bulk extract. The state’s bulk corporate dataset is sold as a paid subscription product and is not part of this integration. Every call returns the register’s current state.

Company Identifiers

Query Identifiers

Identifier Type	Format	Example	Notes
Charter Number	8 or 9 digits followed by a 1 or 2 letter entity-type suffix. Single-letter suffixes are space-padded. Two-letter suffixes are flush.	`19970058LP`	The unique, constant identifier the Maine SoS assigns to each entity. Accepted with or without the separating space.

Both 19340021 D and 19340021D resolve to the same entity. The canonical form returned in API responses preserves the space for single-letter suffixes (19340021 D) and is flush for two-letter suffixes (19970058LP).

Identifiers in API Response

Identifier	Format	Example	Found In
`charterNumber`	8-9 digits + 1-2 letter suffix	`19970058LP`	All entities

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By Name	2-200 chars	`"L. L. BEAN"`	Substring (case-insensitive)	Up to 100
By Charter Number	8-9 digits + 1-2 letter suffix	`19970058LP`	Exact	Single entity

Name searches return one row per entity-name variant: an entity appears once under its legal name and once per assumed or former name. Results are deduplicated by charter number before being returned, preferring the legal-name row.

Quirks & Gotchas

Quirk	Details
Charter suffix encodes entity type	Single-letter suffixes (`D`, `F`, `N`) are written space-padded in the official register and in API responses. Two-letter suffixes (`LP`, `DC`, `FC`) are flush. The suffix is informative but the Filing Type field on the entity profile is authoritative for legal form.
Domestic vs foreign	Foreign entities (those formed outside Maine but qualified to do business in the state) carry suffix codes starting with `F` or `L` and a Filing Type that ends with “doing business in Maine”. They use a `qualificationDate` rather than a `registrationDate` in the source.
No officers or directors	Maine does not publish officer or director rosters on the public register. The only person returned is the clerk or registered agent, surfaced as an `otherKeyPerson` with the role “Clerk / Registered Agent”.
Registered agent can be a person or a company	The agent is returned as `type: "individual"` when the name is a natural person and `type: "company"` when it is a registered-agent service (CT Corporation, Cogency, Northwest Registered Agent, etc.). The mapping is based on common corporate suffixes and service keywords.
No shareholders or beneficial owners	Shareholder and beneficial-ownership records are not collected at the state level. Federal beneficial-ownership records are restricted and not part of this dataset.
No activity codes	The Maine SoS does not collect NAICS, NACE, or ISIC industry classifications.
Status is a short closed list	`GOOD STANDING` is the only active value. Every other observed value (administratively dissolved, dissolved, merged, expired, withdrawn, authority revoked, converted, not in good standing) maps to `active: false`. New status strings introduced by the SoS are surfaced verbatim rather than rejected.
Marks are excluded from search	Trademarks and service marks carry their own charter-number suffix (`M`). They are entities in the SoS register but are not companies. They are intentionally excluded from company-level results.
Pre-image-era filings are paper-only	Filings indexed in the register but flagged as “Image not available” predate digital imaging. Maine offers paper retrieval for these by direct request to the Division. They are intentionally excluded from the available documents list.

Mappings

Company Status

The Status field is read verbatim from the Information Summary. Only GOOD STANDING is treated as active. The list below covers the values observed across business corporations, LLCs, limited partnerships, and domestic and foreign nonprofit corporations.

Local Status	English Translation	Standardized
GOOD STANDING	In good standing	Active
NOT IN GOOD STANDING	Not in good standing	Inactive
ADMINISTRATIVELY DISSOLVED	Administratively dissolved	Inactive
DISSOLVED	Dissolved	Inactive
MERGED	Merged	Inactive
EXPIRED	Expired	Inactive
WITHDRAWN	Withdrawn	Inactive
AUTHORITY REVOKED	Authority to do business revoked	Inactive
CONVERTED	Converted to another form	Inactive

The list is open. A new status value introduced by the Division is returned verbatim as status.localName, with active: false unless it matches GOOD STANDING.

Legal Forms

The standardized legal form is derived deterministically from the entity-type suffix on the charter number. The local name returned in the API response is the Filing Type string the Information Summary actually displays (for example BUSINESS CORPORATION DOING BUSINESS IN MAINE for a foreign business corporation), falling back to the table label when the field is empty.

Domestic entities

Suffix	Local Name	English Translation	Standardized
`D`	Business Corporation	Business Corporation	Corporation
`B`	Business Corporation	Business Corporation	Corporation
`CP`	Business Corporation	Business Corporation	Corporation
`RR`	Railroad Corporation	Railroad Corporation	Corporation
`I`	Insurance Corporation	Insurance Corporation	Corporation
`DC`	Limited Liability Company	Limited Liability Company	Limited Liability Company
`DP`	Limited Liability Partnership	Limited Liability Partnership	Partnership
`LP`	Limited Partnership	Limited Partnership	Partnership
`ND`	Nonprofit Corporation (Title 13-B)	Nonprofit Corporation	Nonprofit Organization
`N`	Nonprofit Corporation (Title 13)	Nonprofit Corporation	Nonprofit Organization
`L`	Nonprofit Local Independent Church	Nonprofit Local Independent Church	Nonprofit Organization

Foreign entities

The Filing Type for these forms ends with “doing business in Maine”.

Suffix	Local Name	English Translation	Standardized
`F`	Business Corporation (foreign)	Foreign Business Corporation	Corporation
`FC`	Limited Liability Company (foreign)	Foreign Limited Liability Company	Limited Liability Company
`FP`	Limited Liability Partnership (foreign)	Foreign Limited Liability Partnership	Partnership
`LF`	Limited Partnership (foreign)	Foreign Limited Partnership	Partnership
`NF`	Nonprofit Corporation (foreign)	Foreign Nonprofit Corporation	Nonprofit Organization

ISO 20275 (ELF) codes are not assigned. The Legal Entity Identifier authority does not publish stable codes for Maine-specific sub-national legal forms. The standardized category above is the recommended cross-jurisdiction key.

Excluded suffixes

Name reservations and trademark filings carry their own charter-number suffixes and are not companies. They are intentionally excluded from results.

Suffix(es)	Meaning
`M`	Mark (trademark or service mark filing)
`RC`, `RD`, `RN`, `RP`, `LN`, `CR`, `LR`, `NR`, `PR`, `R`	Name reservation or registration of a reserved name

Other Key Persons

Maine publishes only one role on the public register. It appears as an otherKeyPerson on the company profile, not as a legalRepresentative.

Local Role Name	English Translation	Notes
Clerk / Registered Agent	Clerk (domestic) or Registered Agent (foreign)	Service-of-process designee. Returned with full name and address. Can be a natural person or a company.
