This is a scam. I received a text message that I won a $500 gift card from Target. It isn't Target. It wants you to enter the code number 6655 which they give you. After you enter the code it takes you to an invalid website. Be careful with this. They are loooking to get information from you to scam your credit card accounts etc.   Google "Claiming free Target gift card scam"  for more information.
