How to File a Fictitious Name for an LLC in Mississippi

By Edmond Hui · Last updated October 6, 2026

Short answer

Mississippi does not require an LLC to register a fictitious name; registering is optional. Mississippi registration is voluntary, so an LLC may trade under another name without filing. Registering puts the name and its owner on the state's public record. An LLC files the Fictitious Business Name Registration with the Secretary of State, Business Services Division.
