What is the difference from a Realtor and a Real Estate agent?

We have many Real Estate agents who contact us and are confused on what the difference is between a Realtor and a Real Estate agent. Everyone who has a Real Estate license could be considered a Real Estate agent. The term Realtor is only used for Real Estate agents who are members of the National Association of Realtors. This name is trademarked and you cannot use the title unless you are a member.
