The refer-a-friend benefit is a way for you to earn extra Exxon Mobil Rewards+ points by inviting your friends, family, or colleagues to join our rewards program. To refer-a-friend, open the app and go to "account" > "Refer-a-friend". Generate the referral code and opt to send it via SMS, email, or more to a friend, family or colleague, and have them enter it during the rewards program registration. The only place you can find the referral code is in the app. When they use the code to join Exxon Mobil Rewards+ program and complete their first loyalty loyalty fuel purchase (min. 5 gallons) or qualifying C-store purchase, you and your friend will receive 100 bonus points each.
