Receiving verification codes for someone else's Apple ID

hi there

Please try this

• Do not share the code: Never tell anyone the verification code or enter it on a suspicious link. Apple will never call, text, or email asking you for a verification code. 
• Check the message details: Look at the text message or email closely to see if it names a specific email address or hint of the account trying to log in
• Remove your phone number or email from the account:
  • If you know which Apple ID the code belongs to (or if you have access to that account via Apple Account Management), sign in, go to Sign-In and Security, and remove your phone number or email address from their trusted contact list. 
• Watch out for phishing attempts: Sometimes, scammers send fake verification codes paired with a text or call pretending to be Apple support ("Your account has been locked, click here to verify"). Delete these messages and do not click any links. 
• Contact Apple Support: If the text messages or alerts do not stop and you cannot remove your info, reach out directly through the Apple Support Official Website to report the misuse of your phone number or email address.

Hello,

You seem to get this weird thing that I had. I told my best friend because I knew it was his. What you should do: email this person, see if they are a scammer or not. If they are then you should call apple and they would sort it out for you.
