Is the referral code generator really free?

Yes. The BLOOP referral code generator is free to use, with no sign-up needed to generate codes.

How do I create an affiliate code?

Use this generator to create a batch of unique codes, then assign one code to each affiliate and share it with them. To track affiliate orders and commissions, set up affiliates in BLOOP: each approved affiliate gets a unique referral link, and you can assign their code as a personal discount coupon.

Can I generate coupon codes for a campaign?

Yes. Generate a batch, then use the codes as discount codes for a campaign, a partner or a giveaway. Each code in a batch is unique.

How many referral codes can I generate at once?

You choose the quantity in the tool before you click generate. For larger batches, download the result as a CSV instead of copying it.

How do I track referral codes after I generate them?

A code generator only creates the codes. To credit referrers, apply rewards and see revenue per code, use a referral app. BLOOP supports referral links and codes, with a custom code prefix, on Shopify. The Free plan costs $0 and includes 10 referee orders and 10 affiliate orders, and Premium is $59.90 per month with a 7-day trial.

What is the difference between a referral code and a referral link?

A referral code is a short code a friend types at checkout. A referral link is a URL that carries the referrer's identity when clicked. Codes suit word of mouth and offline sharing, while links suit email and social posts.

BLOOP referral code generator introduction

What is a referral code generator?

A referral code generator is a tool that creates unique, customizable codes consisting of letters, numbers, and sometimes symbols. These codes are used in customer referral programs to track referrals and assign rewards or incentives accurately. Each code is unique within the generated set and can be designed to represent a brand or promotion. When customers share their referral codes and new users apply these codes during sign-up or purchase, the system credits the original customer for the referral, enabling reward distribution. Referral code generators automate the creation of these codes to simplify management and tracking in referral marketing campaigns.

How does the BLOOP referral code generator work?

The BLOOP referral code generator works through a simple three-step process:

Step 1: Choose Settings

Users first select the number of codes they want to generate, the desired length of each code, and the format options—such as using only letters, numbers, or a combination of both.

Step 2: Generate Codes

After confirming the settings, users click the "generate" button. This instantly creates unique referral codes in accordance with the chosen parameters.

Step 3: Copy or Download

Once codes are generated, users can either copy all codes directly or download them as a CSV file for further use in their referral program.

How to use these referral codes?

To use referral codes generated by tools like BLOOP, follow these steps in your referral program:

Sharing the Code

After codes are generated, distribute them to participants—such as existing users, advocates, or customers—typically through email, social media, text messages, or within your app or website.
Each participant receives a unique referral code to share with friends, family, or their network.

Using the Code

When new users are invited to join your service or make a purchase, they enter the referral code during signup, registration, or checkout.
The system then recognizes the code and credits the referral to the person who shared it.

Tracking and Rewarding

The referral program tracks successful referrals using the unique codes.
Both the referrer (advocate) and the referee (new user) may receive rewards, discounts, or other incentives when the code is used and the new user completes the desired action (such as signing up or purchasing).
Program administrators can monitor redemptions and distribute rewards based on the referral activity.
