A referral code is a unique combination of letters and/or numbers that identifies participants in a brands customer referral program. Referral codes are assigned to every customer who joins the program and are used to track and connect every step of the referral process, from when a customer sends a referral to whether these referrals end up making a purchase. Referral codes are usually given from a company to members of its audience as a promo code that they can share with their friends and family. Referral codes make the entire referral process easier and more efficient for everyone involved, automating and tracking every step of the referral program. Referral codes can be part of a referral link or can be typed manually while placing an order or creating an account. Referral codes can be used to identify, keep track of, and measure the positive impact of existing customers in a companys referral program. Referral codes can also help boost brand recognition and foster relationships with customers.
