Referral codes and promo codes can both provide signup rewards or discounts, but they usually work differently. Referral codes are generally connected to an existing customer, creator or partner. Promo codes are generally issued directly by the business as part of a marketing campaign.

What is a referral code?

A referral code identifies the person, creator or partner responsible for a signup. It connects a new account with an invitation, and may allow the new customer, referrer or both people to receive a reward.

The reward may require account opening, verification, a deposit, a purchase or another qualifying action. Some referral programs use a tracked link rather than a manually entered code. Read how referral bonuses work for the wider process.

What is a promo code?

Promo codes are normally created and distributed by the business. They may appear in advertising, email campaigns, seasonal promotions or partner campaigns.

Common rewards include discounts, free delivery, account credit or introductory offers. Promo codes generally do not reward an existing customer for bringing in the new user.

Can you use a referral code and promo code together?

There is no universal rule. Both rewards may be allowed, only one may apply, a referral offer may replace a public welcome promotion, or the public promotion may apply alongside a separate referral reward.

Do not assume offers stack. Check the terms and conditions before signup, including which offer takes priority and whether the new-customer requirements are the same.

Which one gives the better deal?

Compare total value and requirements rather than assuming one type is better. Consider reward value, minimum deposit or spend, fees, waiting periods, holding requirements and eligibility conditions.

Also check whether both the new user and referrer benefit, and whether the reward is cash, credit, shares, points or a discount. Compare ReferralMate's current best offers before deciding.

Common mistakes to avoid

  • Signing up before applying the referral
  • Assuming a referral link was tracked
  • Expecting two offers to stack
  • Using an expired offer
  • Ignoring minimum deposit or spending requirements
  • Confusing a referral link with an affiliate link
  • Choosing the largest advertised reward without checking the conditions

Referral code, promo code, coupon code and discount code

Promo code, coupon code and discount code are often used interchangeably. They normally describe a code that activates a business marketing offer.

Referral code usually describes the relationship or tracking mechanism rather than only the reward type. It may deliver a discount, but it can also show who invited the new customer and which referral terms apply.

Frequently asked questions
