How do referral codes work? A referral code is typically a unique code or identifier that connects a new customer’s signup or purchase to the person who referred them. If the referral meets the program’s requirements, the new customer, the referrer, or sometimes both may receive a reward.
Referral programs are common among shopping apps, delivery services, financial apps, subscription services, and other online businesses. However, the reward and eligibility rules can vary significantly from one program to another.
This guide explains how referral codes work, who receives the reward, when rewards are credited, and what you should check before using or sharing a referral code.
How Do Referral Codes Work?
Referral codes generally allow a company to identify which existing customer introduced a new customer to its service.
A typical referral process looks like this:
- An existing customer receives a unique referral code or referral link.
- The customer shares that code or link with another person.
- The new customer signs up through the referral link or enters the referral code.
- The new customer completes whatever qualifying action the program requires.
- The company verifies that the referral satisfies its terms.
- The applicable referral reward is credited to the eligible participant or participants.
The qualifying action is important. Simply entering a referral code doesn’t always trigger a reward immediately.
What Is a Referral Code?
A referral code is a code associated with a person participating in a company’s referral program.
It may consist of:
- Letters
- Numbers
- A combination of letters and numbers
- A personalized identifier
The code helps the company attribute an eligible signup, order, or other qualifying action to the referring participant.
Some companies use a referral link instead of—or in addition to—a manually entered code. When someone follows that link, referral information may be associated with the signup automatically.
What Is a Referral Link?
A referral link is a unique URL that contains information identifying the person making the referral.
Instead of manually typing a code, the invited person follows the referral link and completes the signup or purchase process.
Depending on the program, a referral link may:
- Automatically associate the new signup with the referrer
- Open a signup page
- Open the company’s app
- Display the available referral offer
- Provide instructions for completing the qualifying action
Always follow the specific program’s instructions. Some programs require a referral link, while others allow a code to be entered manually.
Who Gets the Referral Reward?
That depends entirely on the referral program.
There are three common structures.
Both People Get a Reward
Some referral programs provide a benefit to both the existing customer and the person being referred.
For example, the new customer might receive an introductory discount while the referrer receives account credit after the qualifying action is completed.
Only the Referrer Gets a Reward
Some programs reward the existing customer for making a successful referral but don’t provide a separate referral benefit to the new customer.
The new customer may still qualify for other introductory promotions, depending on the company’s terms.
Only the New Customer Gets a Benefit
Other programs may use referral-style invitations primarily to provide a signup benefit to the invited customer.
Never assume both people receive the same reward. Check the current terms before using or sharing a referral offer.
When Do You Get a Referral Bonus?
Referral bonuses aren’t always credited immediately after someone enters a code.
A program may require the referred person to complete an additional qualifying action, such as:
- Creating an eligible new account
- Verifying the account
- Completing a first purchase
- Meeting a minimum purchase amount
- Completing a qualifying transaction
- Keeping an order from being canceled or refunded
- Completing the required activity within a specified period
The reward may then be credited immediately or after a waiting or verification period.
Read the referral terms to understand exactly what must happen before expecting a reward.
Do You Have to Be a New Customer to Use a Referral Code?
Many referral programs are designed to bring new customers to a company, so the person being referred often needs to meet the program’s definition of a new customer.
However, eligibility rules vary.
A program may consider factors such as:
- Whether you’ve previously had an account
- Whether you’ve previously completed an order
- Whether you’ve already used an introductory offer
- Whether your account was specifically invited
- Your geographic location
- Other program-specific requirements
Creating another account doesn’t necessarily make someone eligible for another new-customer or referral reward. Follow the company’s account and referral-program rules rather than attempting to work around eligibility restrictions.
The same issue occurs with introductory coupon offers. Our guide explaining why new customer promo codes don’t work for existing users provides more information about new-customer eligibility.
Where Do You Enter a Referral Code?
The location varies by company.
You might be asked for a referral code:
- While creating your account
- On a dedicated referral screen
- Inside the company’s app
- Before placing your first order
- During checkout
- Through a referral link instead of a code field
Don’t assume that a referral code belongs in the ordinary coupon box.
A company may process referral codes and promotional codes through completely different systems.
If the offer specifically instructs you to use the normal checkout promotion field, our guide on where to enter promo code at checkout explains how to locate common coupon fields.
Do You Have to Enter the Referral Code Before Signing Up?
Sometimes.
Certain programs require the referral relationship to be established during account creation. Others may provide a limited opportunity to enter a referral code after signup.
If you create the account first and try to add the referral later, the program may not allow it.
The safest approach is to read the referral instructions before completing registration and use the required referral link or code at the specified stage.
What Happens After You Use a Referral Code?
Using the code generally allows the company to associate your account with the referral.
You may then need to complete additional requirements before any reward becomes available.
For example, a program might require you to:
- Register through an eligible referral.
- Complete your account setup.
- Make a qualifying first purchase.
- Meet any minimum transaction requirement.
- Wait for the transaction to be verified.
Only after those requirements are satisfied might the referral be considered successful.
Why Didn’t My Referral Code Work?
A referral code can fail for several reasons.
Possible explanations include:
- You aren’t considered a new customer
- The referral code was entered incorrectly
- You signed up before using the referral
- The referral offer has ended or changed
- The offer isn’t available in your location
- The qualifying purchase hasn’t been completed
- The minimum transaction requirement wasn’t met
- The referral limit has been reached
- The account or transaction doesn’t meet program requirements
If a code is rejected, check the program’s current terms before assuming that the code itself is invalid.
This is similar to other promotional-code problems. See why promo codes don’t work for a broader explanation of common discount eligibility issues.
Are Referral Codes the Same as Promo Codes?
Not necessarily.
A promo code is generally used to activate a promotional offer or discount. A referral code is generally used to connect an eligible new customer or qualifying action with the person who made the referral.
There can be overlap because a referral program may also give the new customer a discount.
For example, a referral code could simultaneously identify the referrer and activate a new-user benefit.
But the underlying purpose of the two codes can still be different.
Can You Use a Referral Code and a Promo Code Together?
Sometimes, but don’t assume they can always be combined.
Whether both can be used depends on how the company structures its referral and promotional programs.
Possible outcomes include:
- Both benefits are allowed
- The referral benefit replaces another new-user promotion
- Only one introductory offer can be used
- The referral is tracked separately from the checkout coupon
- One promotion makes the other ineligible
Read the terms for both offers before trying to combine them.

Can Referral Rewards Expire?
They can.
A referral program may place a deadline on completing the qualifying action, and a reward that has already been earned may also have its own expiration rules.
For example, referral credit might need to be used within a particular period after it is issued.
Check both:
- The deadline for earning the reward
- The deadline for using the reward after it is credited
These can be two separate dates.

Can You Share Your Referral Code Publicly?
Whether you can publicly share a referral code depends on the individual referral program’s terms.
Some programs encourage customers to share referral links with friends, family, or their networks. Others restrict where or how referral codes may be promoted.
Before publicly posting a referral code on a website, social network, forum, or other public platform, review the program rules for restrictions involving:
- Public posting
- Paid advertising
- Search advertising
- Social media promotion
- Coupon websites
- Commercial websites
- Misleading claims
- Self-referrals
If you’re receiving a benefit when someone uses your referral, disclose that relationship clearly where appropriate.
Is It Safe to Use Someone Else’s Referral Code?
A referral code from a legitimate program is generally designed to be shared, but you should still verify the offer and the destination before signing up.
Be cautious if a referral promotion asks you to:
- Send money directly to the person sharing the code
- Provide passwords or verification codes
- Share unnecessary sensitive information
- Install software from an unofficial source
- Use a suspicious website that imitates the company’s real site
Whenever possible, confirm the promotion through the company’s official website or app.
Similar precautions apply when evaluating coupons found online. See how to tell if a coupon code is legit for additional safety checks.
How Can You Tell if a Referral Reward Was Applied?
Check the account or referral section provided by the company.
Depending on the program, you might see:
- A pending referral
- A completed referral
- Account credit
- Reward points
- A coupon or discount
- A cash reward
- A referral history
If the referral is still pending, check whether the invited person has completed all required qualifying actions.
Remember that some programs don’t disclose detailed information about another person’s account activity, so the amount of referral-status information available may be limited.
What Should You Check Before Using a Referral Code?
Before relying on a referral offer, check:
- Who qualifies as a new or referred customer
- What reward the new customer receives
- What reward the referrer receives
- What qualifying action is required
- Whether there is a minimum purchase
- Whether geographic restrictions apply
- When the referral must be completed
- When the reward will be credited
- Whether the reward expires
- Whether the offer can be combined with another promotion
Checking these details before signup can prevent confusion after the referral has already been submitted.
Quick Referral Code Checklist
Before using or sharing a referral code:
- Verify that the referral program is current
- Read the eligibility requirements
- Check whether the new customer must use a link or code
- Use the referral at the required stage of signup
- Complete any required qualifying action
- Check when rewards are credited
- Review any expiration rules
- Follow the program’s sharing restrictions
- Disclose your referral benefit when appropriate
Final Thoughts
So, how do referral codes work? They generally allow a company to connect a new customer’s eligible signup or transaction with the existing customer who referred them. If the referral meets the program requirements, one or both participants may receive a reward.
The important part is that entering a referral code alone doesn’t always guarantee a bonus. New-customer eligibility, qualifying purchases, minimum transaction amounts, deadlines, locations, referral limits, and other program rules can determine whether a reward is earned.
Before using or sharing a referral code, check the current terms, understand who receives the benefit, and make sure the required steps are completed. That gives both the referrer and the new customer a clearer idea of what to expect.
Frequently Asked Questions
How do referral codes work?
Referral codes generally connect an eligible new customer’s signup or qualifying transaction to the person who referred them. If the program requirements are met, the new customer, the referrer, or both may receive a reward.
Who gets the reward from a referral code?
It depends on the referral program. Some programs reward both the referrer and the new customer, while others provide a benefit to only one participant. Check the current program terms to see who qualifies and what each person receives.
Do you have to be a new customer to use a referral code?
Many referral programs require the referred person to be a new customer, but the exact definition of a new customer varies. Previous accounts, orders, introductory offers, location, and other eligibility requirements may affect whether a referral qualifies.
Can you use a referral code and a promo code together?
Sometimes. A company may allow a referral benefit and promo code to be combined, track them separately, or limit customers to one introductory offer. Check the terms of both promotions before assuming they can be used together.
Why didn’t my referral code work?
A referral code may not work if the customer is ineligible, the code was entered incorrectly, signup occurred before the referral was applied, a required purchase was not completed, the offer ended, or another program requirement was not satisfied.
