Data Availability

API access: US-MS is not yet part of the public countryCode enum. Contact us to enable it on your workspace. Requests sent with countryCode: "US-MS" will otherwise return 400 until the enum is expanded.

Data Sources

Mississippi uses a single integration against the Mississippi Secretary of State, Business Services portal (corp.sos.ms.gov). The register covers all for-profit corporations, limited liability companies, non-profit corporations, limited partnerships, limited liability partnerships, general partnerships, sole proprietorships, cooperatives, foreign business trusts, and the foreign variants of these structures registered to do business in Mississippi. Each entity on the live portal carries a numeric Business ID as its primary identifier, together with the legal name, filing type, status, formation date, principal office address, registered agent, full officer and director roster (name, mailing address, and title), and name history.

Mississippi does not publish a bulk data extract or open-data feed. All data is fetched live from the Secretary of State public portal on each request.

Company Identifiers

Query Identifiers

Identifier Type	Format	Example	Notes
Business ID	Numeric, typically 6-7 digits	`104297`	Unique identifier assigned by the Mississippi Secretary of State. No leading zeros.

Use /v2/search to resolve a company name to its Business ID before calling /v2/company. The Business ID returned by search is the exact value to pass as id in the profile request.

Identifiers in API Response

Identifier	Format	Example	Found In
`businessId`	Numeric, typically 6-7 digits	`104297`	All entities

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By Name	2-100 chars	`"Delta Power"`	Starts-with (case-insensitive)	Multiple results
By Business ID	Numeric	`104297`	Exact (`matchType: id`)	Single result

Name search anchors on the beginning of the legal name. The result set is capped at 50 matches. Use a more specific query string to narrow results. The same entity may appear multiple times in name-search results when it has aliases or a prior legal name; deduplicate on the entity’s Business ID.

Quirks & Gotchas

Quirk	Details
Multiple name rows per entity	A single entity can appear more than once in name-search results when it carries aliases or previous legal names. Deduplicate by Business ID.
Name Reservations have no Business ID	Administrative name reservations do not receive a Business ID. They appear in search results but cannot be profiled and are outside company entity scope.
Empty detail page for some dissolved entities	A small number of dissolved entities return an empty detail page from the register. The API returns `resource_not_found` for these cases; retrying will not help.
Officers holding multiple roles	The register stores compound titles (for example “President, Chairman, Chief Executive Officer”). Topograph splits these into one entry per role in `legalRepresentatives`.
Empty officer title	Some officers appear in the register with no title at all. These records are still returned in `legalRepresentatives` with the person’s name and address; the role fields will be absent or unspecified.
No shareholder or UBO register	Mississippi does not publish shareholders or beneficial owners for any entity type.
No activity codes	The Secretary of State does not publish NAICS, NACE, or ISIC codes on the entity detail page.
Sole proprietorships included	Unlike many US states, Mississippi publishes sole proprietorship registrations and fictitious name (DBA) registrations alongside corporate entities.
Trade Register Extract is included	The printable detail page is bundled with the company data at no extra charge. See Documents below.

Mappings

Legal Forms

The Filing Type field on the portal is a closed vocabulary of 14 values. These were enumerated from live portal data by sweeping ten distinct name-search queries across the full register.

All 14 Mississippi entity types

MS Filing Type	Standardized	ISO 20275
Business Corporation	Corporation	`C3JQ`
Foreign Corporation	Corporation
Limited Liability Company (LLC)	LimitedLiabilityCompany	`JY0X`
Foreign Limited Liability Company (LLC)	LimitedLiabilityCompany
Non-Profit Corporation	NonprofitOrganization	`4RCO`
Foreign Non-Profit Corporation	NonprofitOrganization
Limited Partnership (LP)	Partnership	`T91T`
Foreign Limited Partnership (LP)	Partnership
Limited Liability Partnership (LLP)	Partnership
General Partnership	Partnership
Cooperative	Cooperative
Foreign Business Trust	Trust
Sole Proprietorship	SoleProprietorship
Name Reservation	Other

Foreign variants carry no ISO 20275 ELF code because the ELF code belongs to the jurisdiction of formation, not the state of registration. See the pricing page for the full searchable table.

Officer Roles

The register publishes officer titles as free text. The set of observed values is small and largely closed. Topograph maps each raw title to a standardized role.

Common Register Title	Standardized	Notes
President	President
Vice President	VicePresident
Secretary	Secretary
Treasurer	Treasurer
Director	Director
Chairman	Chairman
Chief Executive Officer	ChiefExecutiveOfficer
Chief Financial Officer	ChiefFinancialOfficer
Assistant Secretary	AssistantSecretary
Assistant Treasurer	AssistantTreasurer
Incorporator	Incorporator	Formation-time role only
Other	Other

Officers holding multiple titles are emitted as separate legalRepresentatives entries, one per role. The Registered Agent is returned under otherKeyPersons (not legalRepresentatives) as a service-of-process designee.

Company Statuses

Mississippi publishes 12 distinct status values. Entities in Good Standing are active and in compliance. All other statuses indicate an inactive or terminated state.

Register Status	Notes
Good Standing	Active and in compliance
Dissolved	Voluntarily or administratively dissolved
Cancelled	Registration cancelled
Revoked	Authority to do business revoked
Withdrawn	Foreign entity withdrawn from Mississippi
Merged	Entity merged into another entity
Inactive	No longer active
Void-Failure to File	Voided for failure to file required reports
