Why is my phone sending a message that I didn't send?or write?!

[AC Question]

Today I woke up and went to my messages to send a friend a text and a number on there caught my eye because all my contacts have names and that one didnt , it was just a number that I didn't recognize ..so I clicked on the message and it was an out going message from me with a code !!? I never sent that!? What's going on ? I'm a little worried
