For Limited Liability Companies (LLCs), the name must contain the words 'Limited Liability Company' or the abbreviation 'LLC' or 'L.L.C.' It must also be distinguishable from the names of other LLCs or corporations already on file with the Secretary of State. This means your name can't be identical or deceptively similar to an existing registered entity. For corporations (both

For sole proprietorships and general partnerships, registering a DBA with the county clerk is the primary method. However, for LLCs and corporations registered with the state, they can also file a 'Business Name Registration' (often referred to as a DBA) with the Illinois Secretary of State if they wish to use a name different from their official reg
