When creating an organization, states have requirements regarding business name endings. All states require company suffixes to differentiate organizations from natural or human persons. However, not all states allow business abbreviations, such as “LLC” instead of “Limited Liability Company.” To add to this, many states have designated words that are prohibited either altogether or without authorization. This guide provides information on the requirements for nonprofit and company suffixes in all 50 states.
