To refer a friend just share your referral code with them, and make sure they use it on their initial application.
Where can I find my referral code?
If your zone has an active referral reward you can find your referral code in the ‘Referrals’ section in the rider app. If your app doesn't have a Referral section your zone doesn't currently have a referral reward.
Only one referral code can be used by each applicant. If your friend applies to ride with Deliveroo more than once, using more than one rider’s referral code, only the referral code on the accepted application will be used. If your referral code isn’t the one on their accepted application, you may still see it listed in the 'Referrals' section of your rider app, but you won’t be eligible for referral fees.
You can find the list of referral rewards here.
