How Business Name Availability Works in Mississippi
Mississippi moved its business filings almost entirely online: the Secretary of State's corporate filing portal handles searches, reservations, formations, and annual reports, and paper is the rare exception. The business search is free and covers the entities and reserved names your proposed name will be checked against.
The availability standard is the modern one — "distinguishable upon the records of the Secretary of State" under Mississippi Code § 79-29-109(1)(c). What sets Mississippi apart is the reservation mechanics: $25 buys a 180-day hold under § 79-29-111(2), one of the longest single terms anywhere, but it is nonrenewable, and the same applicant cannot re-reserve the same name until 60 days after expiration. There is no chaining reservations here.
The rest of the cost picture is friendly: the LLC filing fee is just $50, the annual report is required but free for domestic LLCs, and the optional fictitious-name registration is $25. If you want a cheap state to test a business idea under a protected name, Mississippi makes a strong case.

How to Check Name Availability in Mississippi
Use the tool above to open the Mississippi Secretary of State — Business Search search and look up existing LLCs, corporations, and reserved names. Mississippi's name reservation runs a generous 180 days but cannot be renewed — and the same applicant is locked out from re-reserving the same name until 60 days after it expires. Use the window or lose it.
Search the USPTO database at uspto.gov — clearing the Mississippi registry does not protect you from a federal trademark claim.
Check that the matching .com domain is available before you commit — renaming an LLC later means an amendment filing and new bank paperwork.
Confirm your name is free on Instagram, X, Facebook, and LinkedIn so your branding stays consistent everywhere.

Frequently Asked Questions
How do I check if a business name is taken in Mississippi?
Use the Mississippi Secretary of State's free business search inside its online corporate filing portal. It covers registered entities and reserved names — the records your proposed name must be distinguishable from under Mississippi Code § 79-29-109(1)(c). Search variants and word stems too, since punctuation or designator changes will not make a similar name available.
How much does it cost to reserve a business name in Mississippi?
A Mississippi name reservation costs $25 and holds the name for 180 days under Mississippi Code § 79-29-111(2), filed online through the Secretary of State's portal. It is nonrenewable, and the same applicant cannot re-reserve the same name until at least 60 days after the reservation expires — so start the clock only when your launch fits inside the window.
What suffix does a Mississippi LLC name need?
Mississippi Code § 79-29-109(1)(a) requires an LLC name to contain "limited liability company" or the abbreviation "L.L.C." or "LLC." Corporations must include "corporation," "incorporated," "company," or "limited" (or an abbreviation) under § 79-4-4.01. The name cannot imply the entity is a different type than it actually is.
Is a DBA required in Mississippi?
No — Mississippi is one of the few states where fictitious-name registration is voluntary. You may register a Fictitious Business Name with the Secretary of State on form F0070 for $25, and it is often worth doing: banks commonly require it to open an account in the trade name, and the filing creates a public record of when you began using the name. But there is no legal mandate to register before operating.
What happens if my Mississippi name reservation expires?
The name returns to the available pool, and you specifically are locked out: under § 79-29-111(2) the same applicant cannot reserve the same name again until at least 60 days after expiration. During that gap anyone else can take the name by reserving it or forming an entity. The safest play is to file your Certificate of Formation well before the 180 days run out.
How much does a Mississippi LLC cost to form and maintain?
The Certificate of Formation costs $50, filed online — one of the cheapest formation fees in the country. Ongoing cost is even better: domestic Mississippi LLCs must file an annual report with the Secretary of State, but it is free. Add the optional $25 fictitious-name registration and the optional $25 name reservation, and a fully set-up Mississippi LLC still costs about $100.

Searching Mississippi Names on the Online-Only Portal
The Mississippi Secretary of State's business search is free and lives inside the same online portal used for filings. Search for exact names, then word stems and variants — the "distinguishable upon the records" test means small cosmetic changes to an existing name will not clear a conflict.
Mississippi is essentially online-only: reservations, formations, and annual reports all flow through the portal, so there is no mail lag between finding a clear name and claiming it. That immediacy cuts the risk window that plagues paper states — you can search and file the same afternoon.
Filing the Certificate of Formation costs just $50, among the cheapest in the country. If you are not ready to form, the $25 reservation buys 180 days of protection — but read the fine print on renewal below before you rely on it.
Mississippi Naming Rules and the 180-Day Reservation Lockout
Under Mississippi Code § 79-29-109(1)(a), an LLC name must contain "limited liability company," "L.L.C.," or "LLC." Corporations follow § 79-4-4.01: "corporation," "incorporated," "company," or "limited," or an abbreviation. The name must be distinguishable upon the Secretary of State's records from existing entities and reserved names.
The reservation, under § 79-29-111(2), is where Mississippi gets strict: $25 holds the name for 180 days, but the reservation is nonrenewable. When it lapses, the same applicant cannot reserve the same name again until at least 60 days have passed — a lockout designed to stop indefinite name-parking.
Practically, that means the 180-day clock should start only when your launch is realistically inside it. If you reserve too early and the window closes, your name sits exposed for 60 days during which anyone else — including a competitor — can take it.
Mississippi's Voluntary Fictitious Name Registration
Mississippi treats DBAs unusually: the Fictitious Business Name Registration (form F0070, $25, filed with the Secretary of State) is voluntary. You can lawfully do business in Mississippi under an unregistered trade name — most states make registration a legal prerequisite.
Registering is still usually worth $25. Banks often want the registration before opening an account in the trade name, and the public record establishes your dates of use — useful evidence if a name dispute ever surfaces.
As everywhere, the registration is not a trademark and confers no exclusivity. If the brand matters, clear it against the USPTO database and consider a federal registration; the Mississippi filing only records that you use the name.
