If you mean a Two-Factor Authentication code, it is sent to one of your trusted devices or trusted phone numbers.
This is a user to user forum, you are not addressing Apple Support here. We cannot tell you the verification code because we have no way of knowing it. Even Apple can't know it, since its generated dynamically each time it is required.
If you have not received the code, you can click on "Didn't get verification code" on the sign in screen for options of how to receive one.
