When you do not receive code to your mobile number, email address, or messenger, or your Yahoo verification code not working, click 'Resend' within the first 5 minutes. If you still don't get the code, use a landline number. Make sure there are not any device problems. Ensure your mobile number or alternate email address is correct. Also, your alternate email address hasn't been deleted, the email isn't in your spam folder, and your ISP doesn't block Yahoo.
