# Louisiana (US)
> Country-specific identifiers, data sources, and integration details
## 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.

## 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 Type | Format | Example | Notes |
| ---------------------------- | ----------------------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------- |
| **Louisiana Charter Number** | Up to 10 numeric digits with an optional alpha suffix | `29504510F` | Always 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.
### Identifiers in API Response
| Identifier | Format | Example | Found In |
| --------------- | --------------------------------------- | ----------- | ------------ |
| `charterNumber` | 1–10 digits + optional uppercase letter | `29504510F` | All entities |
## Search Capabilities
| Search Type | Pattern | Example | Match Type | Expected Results |
| --------------------------- | --------------------------------------------- | ----------- | ---------------------------- | -------------------------------------------------------------------- |
| By Louisiana Charter Number | Up to 10 digits + optional letter (uppercase) | `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. 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
| 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. |
| **No shareholder or UBO register** | Louisiana 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 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 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 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 | Director |
| Officer | Officer |
| Member | Member (LLC) |
| Manager | Manager (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 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.
