This number is being used on dating sites.  Where the female member posts it on their profile in hopes that you call them, thinking your talking to a very beautiful women in a city near you.  I got suspicious when the area code did not match any in my area and did a quick search and found complaints at my other sites like this one.  Profile said she was in Frankfort, Kentucky.  But the area code is Maryland (Aspen Hill, Bethesda, Frederick).  Nice try SCAMMER!
