Referral Code

What Is a Referral Code?

A referral code is a unique code assigned to a customer, affiliate, partner, or advocate so a business can track the people they refer.

When someone shares their referral code and a new customer uses it to sign up, make a purchase, book a service, or complete another desired action, the business can identify who made the referral. Depending on the program, the person who shared the code may earn a reward, commission, discount, credit, or other incentive.

Referral codes are commonly used in referral programs, affiliate programs, customer advocacy programs, and partner marketing campaigns.

How Referral Codes Work

Referral codes help connect a new customer back to the person or partner who referred them.

Here’s how the process typically works:

1. A business creates a referral or affiliate program.
2. Each participant receives a unique referral code.
3. The participant shares that code with friends, customers, followers, or their audience.
4. A new customer enters the code during signup, checkout, or booking.
5. The business tracks the referral.
6. The referrer earns a reward if the referral meets the program’s requirements.

For example, a customer might share a code like SARAH10, and anyone who uses that code at checkout receives a discount while Sarah gets referral credit.

A referral code makes it easier to reward the people who are already helping a business grow through word of mouth.

Referral Code vs. Referral Link

Referral codes and referral links serve a similar purpose: they both help businesses track referrals.

A referral link is a unique URL that tracks the referral automatically when someone clicks it.

A referral code is a unique code that the referred customer manually enters during signup, checkout, or another conversion step.

Many businesses use both. A referral link is convenient for online sharing, while a referral code is easy to remember, share verbally, include in social posts, or use in offline conversations.
