Some states allow certain punctuation and special characters, while others restrict what their filing systems accept. The applicable state's naming rules determine what can appear in the official entity name.

Swyft Filings provides business-name resources and performs name checks as part of its filing process. A state name check focuses on whether a proposed entity name can be accepted under that state's naming rules; it does not determine whether the name is clear from every trademark, branding, domain-name, or marketplace conflict.
