REALTOR® is a registered mark which identifies a professional in real estate who subscribes to a strict Code of Ethics as a member of the National Association of REALTORS®, (NAR). Those not affiliated with NAR may not be called, nor may they refer to themselves as REALTORS®. The term REALTOR® does not denote a vocation. It is not a term to be used interchangeably with titles like real estate broker, salesperson, or real estate licensee. There is a difference.
