Can someone tell me if this is a real serial number for coach

 

[Lake Effect]

Maybe yes, maybe no! It may be a legitimate number (I have no idea, I am not familiar with newer styles), but is your question, it your bag legit? If that is your question, post all the info requested on the authentication thread.
Good luck!

A serial number by itself can NEVER prove a Coach is genuine. Do as Lake Effect suggested and go thru the authentication process.
