This guide contains public integration notes for Louisiana. Use it for identifier formats, search behavior, and country-specific caveats. The live source of truth for coverage, pricing, data sources, documents, legal forms, and status values is the pricing page.

Data Sources

Louisiana uses a single integration against the Louisiana Secretary of State, Commercial Division. This is the official register of business filings for the state. It covers domestic and foreign corporations (Title 12 of the Louisiana Revised Statutes), limited liability companies, limited and general partnerships, trade names and trademarks, name reservations, and historical name records.
  • CORAweb commercial-search portal at coraweb.sos.la.gov (verification, primary). The official public lookup served by the Commercial Division. Each query reads live against the register and returns the legal name, Charter Number, entity type, current status with the inactivation reason when applicable, the registration / file / qualified dates, the registered agent or agents with appointment date, the officer roster preserved as filed, and the five address types Louisiana publishes (Domicile, Mailing, Principal Business Office, Registered Office in Louisiana, Principal Business Establishment in Louisiana).
Sole proprietors and most general partnerships file at the parish (county) level and are out of scope at the state level. Trade names (“DBA”) and trademarks are searchable on the same portal but are not full business entities. They appear in search results but are not returned as company profiles.

Company Identifiers

Query Identifiers

Identifier TypeFormatExampleNotes
Louisiana Charter NumberUp to 10 numeric digits with an optional alpha suffix29504510FAlways uppercase, no separators. The suffix appears on most active filings. Older filings may have no suffix.
The Charter Number is shown on every page of the CORAweb portal as Charter Number:. It is the single primary identifier. Louisiana does not assign a separate state-level tax ID, NAICS code, or other public identifier we expose.

Name search returns up to 10 matches. Louisiana’s public results page does not include Charter Numbers, so each match is resolved by reading its underlying profile; the lookups run in parallel, so a full 10-result search typically lands in a few seconds. “Previous Name” and “Trade Name” rows are filtered out because they route to the same underlying entity and would duplicate the real result.

Quirks & Gotchas

QuirkDetails
Charter Number suffix is significantMost active filings have a single trailing letter (e.g. 29504510F, 36528934K). Older records may not. The suffix is part of the identifier and must be preserved in queries.
Five distinct address typesLouisiana publishes Domicile, Mailing, Principal Business Office, Registered Office in Louisiana, and Principal Business Establishment in Louisiana. The first three reflect the entity’s filing wherever incorporated; the last two are mandatory for any entity registered to do business in Louisiana. The API returns the most operationally relevant one as legalAddress.
Inactivation carries a reasonWhen an entity is Inactive, the register also exposes a free-form Inactive Reason (e.g. “Action By Secretary of State”, “Revoked”). The reason is folded into the status localName so customers see both the state and the cause.
Officer titles preserved as filedLouisiana files officer roles as comma-separated titles (e.g. President, Director, Executive Vice-President, Secretary). Roles are returned verbatim. LLCs typically use Member or Manager instead of the corporate vocabulary.
Previous name historyWhen an entity changes its legal name, the prior name(s) are kept on the public record with a change date.
No shareholder or UBO registerLouisiana does not publish shareholders or beneficial owners for any entity type at the state level. Federal FinCEN beneficial-ownership records are restricted and are not part of this dataset.
No industry classificationThe Commercial Division does not collect NAICS, NACE, or ISIC codes.
Apostilles are not orderable onlineApostilled certificates require a phone order through the Commercial Division (225.925.4704). They are not part of this integration.

Mappings

Entity Types

The CORAweb portal renders the entity type as a free-form label. The labels and their standardized mapping are stable; the live mapping is on the pricing page.
CORAweb LabelStandardized FormActive in this dataset
Business CorporationCorporationYes
Business Corporation (Non-Louisiana)CorporationYes
Limited Liability CompanyLimited Liability CompanyYes
Limited Liability Company (Non-Louisiana)Limited Liability CompanyYes
PartnershipPartnershipYes
Partnership (Non-Louisiana)PartnershipYes
Limited PartnershipPartnershipYes
Nonprofit CorporationNonprofit OrganizationYes
Trade NameOther (trade name)Listed only
TrademarkOther (trademark)Listed only
Previous NameOther (name history)Listed only
The (Non-Louisiana) suffix flags foreign entities that are registered to do business in Louisiana but were chartered in another jurisdiction. The data model is the same. The suffix is preserved on the returned legalForm.localName so downstream consumers can distinguish them.

Officer Roles

Louisiana files officer titles as free-form labels and may include multiple titles per officer (comma-separated). The most common values are listed below; less common combinations are preserved verbatim.
Local TitleMapped Role
PresidentPresident
Vice-PresidentVice-President
Executive Vice-PresidentVice-President (Executive)
SecretarySecretary
TreasurerTreasurer
DirectorDirector
OfficerOfficer
MemberMember (LLC)
ManagerManager (LLC)
When an officer holds multiple titles (e.g. President, Director), every title is preserved on legalRepresentative.role.localName. The standardized role reflects the senior-most position.

Status

Louisiana exposes a small set of status values. When an entity is Inactive, the API surfaces the cause in status.localName (e.g. Inactive — Action By Secretary of State).
Local StatusActive
ActiveYes
Inactive — Action By Secretary of StateNo
Inactive — RevokedNo
Inactive — WithdrawnNo
Inactive — MergedNo
Inactive — DissolvedNo
The Annual Report Status (e.g. In Good Standing) is also published on the profile when applicable.
