# Louisiana (US)
> Country-specific identifiers, data sources, and integration details
This guide is outdated and will be removed on 1 November 2026. The up-to-date Louisiana (US) reference is on the [Louisiana (US) country page](https://www.topograph.co/countries/us-la).
## Start here
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.
Open the current catalog for supported datapoints, documents, sources, identifiers, and availability.
This jurisdiction may be in preview or limited availability. Check the live pricing page or contact support before relying on it in production.
Country details below are preserved as integration notes. If a table or example conflicts with the live pricing page, use the pricing page as the source of truth and contact support.

**API access:** `US-LA` is accepted by the API, but it is not yet listed in the request `countryCode` enum of the OpenAPI reference.
## Data Sources
Louisiana data comes from 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.
* **Prefill** (fast, non-authoritative). Answers from a regularly refreshed copy of the register's business-name index: legal name, Charter Number, status (active / inactive) and city. Legal representatives and registered agents come back empty in this mode, and shareholders are not available.
* **Verification** (authoritative). 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 date, the registered agent or agents with their address, the officer roster preserved as filed, owners for member-managed LLCs and registered partnerships, and one entity address chosen from the 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 Type | Format | Example | Notes |
| - | - | - | - |
| **Louisiana Charter Number** | 8 digits followed by one uppercase letter (9 characters), leading zeros included | `29504510F` | No separators. The register documents this shape and requires all 9 characters for a lookup (e.g. `36528934K`, `03002150N`). |
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.
### Identifiers in API Response
| Identifier | Format | Example | Found In |
| - | - | - | - |
| `charterNumber` | 8 digits + one uppercase letter | `29504510F` | All entities |
### Legal Entity Identifier (LEI)
GLEIF is the supplementary data source for this identifier.
`company.identifiers.lei` is returned when a company identifier has a unique match against this jurisdiction's registration or validation references in GLEIF.
An [LEI (Legal Entity Identifier)](https://www.gleif.org/en/about-lei/introducing-the-legal-entity-identifier-lei) has 20 uppercase letters and digits, ending in two check digits.
Coverage varies by entity. The field is omitted when no unambiguous match is available. Lapsed or retired LEIs may be returned; annulled records are excluded.
## Search Capabilities
| Search Type | Pattern | Example | Match Type | Expected Results |
| - | - | - | - | - |
| By Louisiana Charter Number | 8 digits + one letter (all 9 characters) | `29504510F` | Exact | Exact match returned first (matchType: id); other results may follow |
| By name | 2–200 characters | `"Walmart"` | Substring (case-insensitive) | Up to 10 |
Name search returns up to 10 matches, each with its Charter Number. "Previous Name" and "Trade Name" rows are filtered out because they route to the same underlying entity and would duplicate the real result.
### Active companies only
Search can return companies that are no longer active. Each result carries the register's status, so [`activeOnly=true`](/essentials/search#active-companies-only) removes the inactive ones.
## Quirks & Gotchas
| Quirk | Details |
| - | - |
| **Charter Number suffix is significant** | Most 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 types** | Louisiana 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 reason** | When 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 filed** | Louisiana 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 history** | When an entity changes its legal name, the prior name(s) are kept on the public record with a change date. |
| **Owners for some entity types only** | Louisiana publishes the members of member-managed LLCs and the partners of registered partnerships. They are returned as `shareholders` in verification mode, with no ownership percentage (a sole member or sole partner is reported at 100%). Corporations and manager-managed LLCs publish no owners, so the datapoint returns an explanatory error for them. There is no beneficial-ownership register at the state level, and federal FinCEN records are restricted. |
| **No industry classification** | The Commercial Division does not collect NAICS, NACE, or ISIC codes. |
| **Apostilles are not orderable online** | Apostilled certificates require a phone order through the Commercial Division (225.925.4704). They are not part of this integration. |
## Mappings
### Entity Types
The register publishes the entity type as a label. The labels and their standardized mapping are stable.
| CORAweb Label | Standardized Form | Active in this dataset |
| - | - | - |
| Business Corporation | Corporation | Yes |
| Business Corporation (Non-Louisiana) | Corporation | Yes |
| Limited Liability Company | Limited Liability Company | Yes |
| Limited Liability Company (Non-Louisiana) | Limited Liability Company | Yes |
| Partnership | Partnership | Yes |
| Partnership (Non-Louisiana) | Partnership | Yes |
| Limited Partnership | Partnership | Yes |
| Nonprofit Corporation | Nonprofit Organization | Yes |
| Trade Name | Other (trade name) | Listed only |
| Trademark | Other (trademark) | Listed only |
| Previous Name | Other (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 Title | Mapped Role |
| - | - |
| President | President |
| Vice-President | Vice-President |
| Executive Vice-President | Vice-President (Executive) |
| Secretary | Secretary |
| Treasurer | Treasurer |
| Director | Board Member (other key person) |
| Officer | Officer |
| Member | Other (LLC member; authority depends on management) |
| Manager | Manager (LLC) |
When an officer holds multiple titles (e.g. `President, Director`), every title is preserved on `legalRepresentative.role.localName`. Each office is classified separately: an executive office can appear in legal representatives while a governing Director office appears in other key persons. Known labels have deterministic English and standardized meanings; unfamiliar titles retain their source text and may use AI enrichment. Corporate office powers depend on bylaws or board authorization. LLC members represent where management is reserved to members; a manager roster routes nonmanaging members to other key persons. No sole or joint signing mode is inferred.
### 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 Status | Active |
| - | - |
| Active | Yes |
| Inactive — Action By Secretary of State | No |
| Inactive — Revoked | No |
| Inactive — Withdrawn | No |
| Inactive — Merged | No |
| Inactive — Dissolved | No |
The `Annual Report Status` (e.g. `In Good Standing`) is also published on the profile when applicable.
## Statutory Filings
Louisiana entities file an annual report confirming the entity's particulars are current. The register publishes "Last Report Filed", returned on the cross-country [`statutoryFilings`](/essentials/compliance-signals) field as `lastFiled.filedOn`. No forward-looking due date is published.
```json theme={null}
{
"statutoryFilings": {
"annualFiling": {
"cadence": "annual",
"lastFiled": { "filedOn": "2025-04-30" },
"source": "la_sos"
}
}
}
```
US states publish no statutory accounts, so the `accounts` obligation is **absent** rather than returned empty. An empty object would read as "we looked and found nothing", which is a different claim. Placeholder cells such as `N/A` or `Inactive, Not Applicable` are dropped rather than parsed as dates, so an entity with no obligation simply has no `statutoryFilings`.
## Data Availability
| Datapoint | Available | Notes |
| - | - | - |
| Company profile | Yes | Verification: legal name, Charter Number, entity type, status with inactivation reason, registration date, and one entity address as `legalAddress`. Prefill: legal name, Charter Number, status and city. Prior names are not returned in the API response. |
| Registered agent(s) | Yes | Returned as `otherKeyPersons` with the role `registeredAgent`. Includes name and address; the appointment date is not returned. Louisiana allows multiple registered agents per entity. Verification only; empty in onboarding. |
| Legal representatives | Yes | Representing executive and management offices; governing-only directors and nonmanaging members appear in other key persons. Source titles are preserved. Verification only; empty in onboarding. |
| Shareholders | Yes (verification, some entity types) | Members of member-managed LLCs and partners of registered partnerships, with no ownership percentage (a sole owner is reported at 100%). Corporations and manager-managed LLCs return an explanatory error. |
| Ultimate beneficial owners | No | Louisiana does not maintain a public beneficial-ownership register. |
| Activity codes | No | The Commercial Division does not collect NAICS, NACE, or ISIC codes. |
| Trade Register Extract | Yes | Printable PDF of the CORAweb Commercial Search Details page, captured at request time. Included with the company profile at no extra charge. |

## Documents
| Document | Format | Certified | Notes |
| - | - | - | - |
| Trade Register Extract | PDF | No | Printable rendering of the public profile, generated at request time. Included with the company profile at no extra charge. |
| Information Certificate | PDF | Yes | Official certified data snapshot (name, Charter Number, type, status, addresses, registered agent, officers), sealed by the Secretary of State as of the issue date. |
| Certificate of Good Standing | PDF | Yes | Official certificate attesting that the entity exists and is current on filings and fees, sealed by the Secretary of State as of the issue date. |
Both certified documents are issued live by the Louisiana Secretary of State and are retrievable for 120 days after issue. The Trade Register Extract is generated on-demand and reflects whatever the public profile shows at the moment of the request.
Certified documents are paid by the Secretary of State per certificate. See the live pricing page for the current rate.
## Example API Responses
Search returns the exact match first by Charter Number (other results may follow), and the profile carries the foreign-chartered Domicile address alongside the Louisiana registered office.
