Can two businesses in different states use the same name?
Possibly. State entity-name records are generally administered separately, but trademark rights and other naming restrictions can cross state boundaries. Availability in one state therefore does not establish unrestricted rights to the name elsewhere.
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.
Because naming rules are administered by individual states, terms such as distinguishable, reserved, restricted, or prohibited can have different meanings depending on the jurisdiction. A name that is accepted by one state may still be unavailable or problematic in another state or for a separate trademark reason.
