You need to enter your referral code during registration. Once you’ve created your account, it’s no longer possible to add a referral code.
Why can’t I add it later?
Your referral code links your account to the person who recommended Littlebit to you. This connection is established when you create your account, so you need to enter the code during registration.
What if I haven’t completed my registration yet?
If you haven’t created your account yet, make sure to enter your referral code before completing your registration.
If your code isn’t working, don’t complete your registration without it just yet. Check out the article “My referral code isn’t working. What should I do?”
