What is a coupon code leak?

A coupon code leak is when a confidential or exclusive coupon code is made public or shared with unauthorized individuals. Coupon codes are often used by retailers to offer discounts or promotions to customers, and they are typically only valid for a limited time or for a specific group of people.

When a coupon code leak occurs, it can result in unintended discounts being applied to purchases including promo code abuse , which can impact the merchants bottom line.

It can also lead to frustration among customers who were not intended to receive the discount, as well as damage to the retailer’s reputation.

How can you prevent a coupon code leak?

Below are 5 methods a Shopify store can utilize to help prevent and mitigate coupon code leaks:

  1. Use unique and randomly generated coupon codes: By using unique coupon codes that are difficult to guess or replicate, it can be more difficult for unauthorized individuals to access them. You can use a tool to generate random codes or create your own system for creating codes that are hard to guess.
  2. Limit the number of times a coupon code can be used: Setting a limit on the number of times a coupon code can be used can help prevent abuse and ensure that the discount is only being applied to the intended number of purchases.
  3. Set an expiration date for your coupon codes: Expiring your coupon codes after a certain date can help prevent unauthorized individuals from using them after they are no longer valid.
  4. Use customer-specific coupon codes: If you have a specific group of customers that you want to offer a discount to, you can create customer-specific coupon codes that can only be used by those customers. This can help prevent unauthorized individuals from using the code.
  5. Use coupon code tracking software: There are various software tools available that can help you track and manage your coupon codes, including monitoring for any suspicious activity or unauthorized use. These tools can help you identify and prevent coupon code leaks. Below we have listed available tools on Shopify and their benefits.

5 apps to manage and track coupon codes for your Shopify store

  6. If you have an Ambassador program or an App that is generating lots of coupon codes then this can be more challenging. Once you have outgrown the Shopify Admin view for managing coupon codes then one of the above solutions will help you keep on top of coupon leaks and management.



Preventing and managing coupon code leaks is an important aspect of running a successful online store. By using unique and randomly generated codes, limiting the number of times a code can be used, setting expiration dates, using customer-specific codes, and utilizing coupon code tracking software, you can help protect your business and ensure that your coupons are being used as intended.

While it’s not possible to completely eliminate the risk of coupon code leaks, taking these proactive measures can help minimize the risk and safeguard your business.
