Connecticut Corporation Name Requirements

Key Guidelines

Connecticut has official requirements for its corporation names.

The name must contain one of the following words or abbreviations: corporation, incorporated, company, Societa per Azioni, limited, corp., inc., co., S.p.A., ltd., or words or abbreviations of like import in another language.

There are also restricted words, such as “FBI” or “Treasury,” that you cannot use in order to keep your LLC from sounding like an official institution.

Connecticut business names also cannot contain language stating or implying that the corporation is organized for anything other than its permitted purpose.

For more information, check out the Connecticut state statute on corporation names.

Distinguishability

Your name must be distinguishable from all other Connecticut business names. In Connecticut, a distinguishable name is one that is substantively different from all other existing or reserved business names in the state.

If your corporation name isn’t distinguishable, your Certificate of Incorporation filing will likely be rejected.
