"Not registered" is the registry's answer at this moment. It is not a promise that the name can be bought at the standard price, since some unregistered names are reserved or sold at a premium. The buttons open Spaceship, a domain registrar, where the price is shown.

Example: a check of "Blue Heron Bakery LLC" against Mississippi's rules.

Ends with "L.L.C.", an ending Mississippi lists for an LLC.

This checks the ending and the restricted words Mississippi publishes. It does not tell you whether another company already holds the name. Only the state's own search can show that.

How the Mississippi Business Search works

The Secretary of State's Business Search lives on the corp.sos.ms.gov filing system. A stored copy of the search page from November 2026 lists four ways to search: Business Name, Business ID, Officer Name and Registered Agent. The same copy offers five match options: Starting With, All Words, Any Words, Sounds Like and Exact Match. The live form may differ from that copy.

That copy also carries a warning from the state. It says the office has received reports of both fraudulent business filings and lawsuits filed against incorrect business entities. It lists recently named agents too.

What makes a Mississippi LLC name distinguishable

The name rules here come from the Secretary of State's posted copy of the 2010 Act. Amendments may have changed section 79-29-109 since then, and that copy is not a promise of the current text.

In that copy, an LLC name must contain "limited liability company," "L.L.C." or "LLC." It may contain the name of a member or manager. It must be distinguishable on the Secretary of State's records from these entities, if organized or registered in Mississippi and not dissolved:

a domestic or foreign corporation
a nonprofit corporation
a limited partnership
a limited liability partnership
a limited liability company

Words the 2010 Act bars from an LLC name

Section 79-29-109(1)(d) bars these words from an LLC name:

bank, banker, bankers and banking
trust company and trust
insurance
corporation and incorporated
partnership and limited partnership

The bar also reaches any combination or abbreviation of those words, and any words or abbreviations of similar import. A name such as Blue Heron Insurance Group LLC runs into it. So does any LLC name that uses "Corp." or "Inc."

Reserving a Mississippi name for 180 days

The LLC name reservation, form F0110, costs $25 on the fee schedule. Section 79-29-111 of the posted copy has the Secretary of State reserve the name for the applicant's exclusive use for 180 days.

What Mississippi charges after formation

The Certificate of Formation, form F0100, costs $50 on the fee schedule. Articles of Incorporation for a profit corporation also cost $50. The state's FAQ says filing fees are set in statute by the Mississippi legislature.

The LLC annual report costs $0, while a profit corporation pays $25 for its report. Both reports are filed any time on or after January 1 and are due by April 15. A fictitious business name registration, form F0070, costs $25 under the schedule's Trade Names heading.

The state's new-filings page, in a stored copy from October 2026, says business documents may be filed only through the online filing system. The FAQ says online filings that need staff review should be returned within 24 hours of submission. Use the LLC cost calculator to total the first year.

Checking and claiming a name in Mississippi

Open the Business Search and search the name by Business Name, trying Starting With, All Words and Sounds Like.
Compare it with the corporations, nonprofits, partnerships and LLCs in the results.
Confirm that the name contains an ending from the name endings for every state and none of the barred words.
Reserve the name for 180 days at $25 if the paperwork is not ready.
File the $50 Certificate of Formation online, then calendar the April 15 annual report.

Mississippi name search questions

Can a Mississippi LLC put a member's name in its name?

Yes. Section 79-29-109 in the posted copy of the 2010 Act says an LLC name may contain the name of a member or manager. The name must still contain "limited liability company," "L.L.C." or "LLC."

Is Inc. or Corp. allowed in a Mississippi LLC name?

Not under the posted copy of the 2010 Act. It bars "corporation" and "incorporated" from an LLC name, along with any abbreviation of those words and words of similar import.

When is the Mississippi LLC annual report due?

The state says the report can be filed any time on or after January 1 and is due by April 15 of that year. Its fee schedule lists the LLC annual report at $0.

What does a foreign LLC pay in Mississippi?

Registering a foreign LLC costs $250 and its annual report costs another $250, according to the Secretary of State's fee schedule. A Mississippi LLC pays $0 for the annual report.

What does reinstating a Mississippi LLC require?

Corporations and certain LLCs seeking reinstatement need a tax clearance letter from the Mississippi Department of Revenue, says the state's FAQ. Not every LLC needs one, since the FAQ names only certain LLCs.
