Hello, this is the Whosfan customer support team.
You can enter only one referral code when you first join the app. If you do not enter a referrer code during the signup, you cannot enter it at a later time. However, when you go to My Page and tap on the Referral Code button, your referral code will be copied onto your clipboard.
Share your referral code with friends on social media or messengers!
Thank you.
