Mississippi Business Entity Search (2026)
The Mississippi business entity search is a free online tool run by the Mississippi Secretary of State. You search by business name or by filing/business ID number, and the record shows the entity's status and standing, formation date, registered agent, principal office, and filing history including annual report status. It is the go-to way to check name availability before forming and to verify a company's good standing during due diligence - at $0.

What the Mississippi Business Entity Search Is
The Mississippi Secretary of State (SOS) maintains a public online registry of every business entity registered to do business in the state - LLCs, corporations, limited partnerships, nonprofits, and foreign entities that have qualified in Mississippi. The business entity search is the free lookup tool on the Secretary of State's Business Services portal that lets anyone view those records. Because business filings are public, you do not need an account or a fee to search; you only pay if you later order a certified copy or file a document.
The registry is the authoritative source for what has been filed with the state about a company. It is the same system where you form and maintain a Mississippi LLC, so the search reflects real-time registration data. Whether you are naming a new company, vetting a vendor, or confirming your own filings are current, this tool is where you start. For the broader formation path, see our how to form an LLC hub and the glossary for the terms used below.
How to Run a Search
Searching is straightforward. From the Secretary of State's Business Services portal, open the business search and choose how you want to look:
- By business name: type the company name or a portion of it. Partial or "starts with" searches help when you are not sure of the exact wording or want to see similar names.
- By filing/business ID number: if you know the entity's state-assigned ID, searching by number takes you straight to the exact record.
Results return a list of matching entities. Click a name to open the full record. If you are checking a common word, expect several matches - review each to find the specific entity. Because the tool searches the live registry, newly filed entities appear once the Secretary of State processes the filing. If you are researching your own company, confirm the details match your articles of organization exactly.
What Data the Record Shows
An entity record on the Mississippi registry typically includes the following fields, which make it useful for a range of tasks:
| Field | What it tells you |
|---|---|
| Entity name and type | Exact legal name and structure (LLC, corporation, LP, nonprofit). |
| Status / standing | Whether the entity is active, dissolved, or otherwise, and whether filings are current. |
| Formation / registration date | When the entity was created or (for foreign entities) qualified in Mississippi. |
| Registered agent & office | Who accepts legal service and the Mississippi address of record. |
| Principal office address | The business's main address on file. |
| Filing history | Formation documents, amendments, and annual report status. |
These fields let you confirm who is behind a company, whether it is current, and where to serve legal papers. The registered agent field is especially useful for contracts and disputes, and the filing history shows whether the entity has kept its annual report up to date.
Using the Search for Name Availability
The most common reason people search before forming is to check name availability. Mississippi, like other states, requires a new entity's name to be distinguishable from names already on the registry. Before you file, search your desired name to see whether an active entity already uses it or something confusingly similar. If the name is clearly taken, choose another; if nothing similar appears, that is a good sign, though only the Secretary of State's review at the time of filing is final.
A clear search does not reserve the name or grant trademark rights - it only shows what is currently registered. If you want to hold a name while you prepare your paperwork, ask the Secretary of State about a name reservation. And remember that a state entity name is different from a brand: to protect a name as a brand, look at trademark registration or a DBA. If you plan to operate under a different name, see Mississippi DBA filing.
Good-Standing and Due-Diligence Checks
The entity search is also a due-diligence workhorse. Before signing a contract, lending money, or buying a business, you can confirm that the other party is a real, registered entity in good standing rather than an inactive or dissolved shell. The status field indicates whether the entity is active and current on filings; a lapsed annual report or an "administratively dissolved" status is a red flag worth investigating. For an official determination, order a Certificate of Good Standing (also called a certificate of existence) from the Secretary of State - the free search is a strong indicator but the certificate is the formal proof banks and courts accept.
Keep in mind what the search does not cover. It shows state registration records only. A federal EIN is a separate IRS number and never appears in the state system, and Mississippi tax accounts are handled by the Department of Revenue (DOR), not the Secretary of State. For tax registration and filings, see Mississippi LLC tax filing and the business tax hub. Used together, the entity search, an EIN, and DOR registration give you the full picture of a Mississippi business.
Frequently Asked Questions
How do I search for a business in Mississippi?
Use the Mississippi Secretary of State's online Business Search on the Business Services portal. You can search by business name or by the filing/business ID number. The tool is free and returns registered entities, their status, and their public filing details.

What information does the Mississippi search show?
A record typically shows the entity name, type, status or standing, formation or registration date, registered agent and office, principal address, and filing history including annual report status. The exact fields depend on the entity type and what has been filed.
Can I check name availability before forming in Mississippi?
Yes. Search your desired name in the registry to see whether an active entity already uses it or a confusingly similar name. Your name generally must be distinguishable from existing names. A clear search suggests availability, but only the Secretary of State's review at filing is final.
Does the entity search confirm good standing?
The search shows a status that indicates whether an entity is active and current on filings, which is a strong indicator of standing. For an official good-standing determination, request a Certificate of Good Standing (existence) from the Secretary of State.
Is a business entity search the same as an EIN lookup?
No. The Mississippi entity search covers state registration records with the Secretary of State. An EIN is a separate federal number issued by the IRS and is not shown in the state search. The two systems and agencies are entirely distinct.
