Guides Plan
Which app generates thousands of unique discount codes on Shopify?
Who this guide is for
This guide is for Shopify merchants who need many different codes for the same deal, for example 1,000 one-time welcome codes for an email list, or one code per influencer. A shared code like WELCOME15 is one string anyone can pass around; unique codes tell you who used which code.
We compared 6 apps that generate unique codes in bulk. Every competitor fact comes from the app's Shopify App Store listing, checked on November 12, 2026. Prices are per month, in US dollars, and can change. For the click-by-click setup, see how to generate 1,000 unique discount codes in Shopify.
Shopstack makes Discount Genie, one of the apps on this list. It is listed first, and every app is described from its own listing.
What Shopify does on its own
The Shopify admin makes one code per discount: its discount page has a Generate code button for one random code and no field for a number of codes. Each item below links the Shopify page it comes from (checked November 12, 2026).
Shopify can
- Create one discount code at a time, typed or randomly generated with the Generate code button. Source: help.shopify.com
- Export your discounts to a CSV file from the Discounts page. Source: help.shopify.com
- Hold up to 20,000,000 unique discount codes per store. Source: help.shopify.com
- Add codes to an existing code discount through the Admin API, up to 250 per request. Source: shopify.dev
Shopify can’t
- Generate many unique codes from the admin. A discount takes one code. Source: help.shopify.com
- Import discount codes. Shopify's export page says: "You can't import discount codes to your store using CSV files." Source: help.shopify.com
- Add more than 250 codes in one API request. Source: shopify.dev
- Go past 20,000,000 codes per store. Apps can't raise that limit either. Source: help.shopify.com
To make one code in the Shopify admin:
- From your Shopify admin, go to Discounts, click Create discount, and in the Select discount type menu click Amount off products or Amount off orders.
- Under Method, select Discount code.
- In the Discount code section, click Generate code for a random code, or type your own name.
- In the Value section, pick Percentage or Fixed amount and enter the amount.
- Under Maximum discount uses, check Limit number of times this discount can be used in total or Limit to one per customer.
You need an app once you want more than a few dozen codes without a developer.
Which bulk code app fits your store
Bulk code apps differ most in how many codes each plan allows and where the codes go after they are made.
- Codes straight into Klaviyo: Discount Genie sends a bulk job to a Klaviyo coupon on its paid plans. Bulk Discount Code Bot syncs codes to Klaviyo on its Grow plan.
- A free plan to start: Entafix (250 codes a month), Code Bulk (500 codes for the life of the store) and Bulk Discount Code Bot (three discount sets).
- The lowest price for unlimited codes: Dyno lists one plan at $9.85 a month for unlimited unique codes.
- Codes for a discount you already have: Code Bulk adds codes to an existing discount, made in Shopify or by another app.
- Bulk codes plus other offers: Discount Genie and Kite also run tiered, BOGO and other discounts in the same app.
Discount Genie
Discount Genie (by Shopstack, the team behind this guide) has 5.0 from 50+ reviews on the Shopify App Store. Install it from Discount Genie on the Shopify App Store.

- Random or your own codes: choose Randomly generate codes and enter the Number of codes, or choose Upload a CSV file with your own list. Duplicate codes in the file are skipped, and the app tells you how many.
- Code shape: a Character length of 7 or more, Numeric, Alphanumeric or Letters, plus an optional prefix and suffix, for example BF26-7QK2M9X.
- CSV download: under Code destination, pick CSV file, then export all, unused or used codes from View my bulk discount codes.
- Klaviyo: pick Klaviyo under Code destination to send the codes to a Klaviyo coupon (Klaviyo steps). Klaviyo takes up to 1,000 codes per job, so Discount Genie sends a 2,500-code job as 3 uploads.
- Refill: Automatically refill codes when running low adds more codes when the job drops to your Refill threshold. It is off by default.

FAQ
How do I make a lot of unique discount codes at once in Shopify?
Use an app with a bulk code generator, because the Shopify admin makes one code per discount and can't import a CSV of codes. In Discount Genie, open Bulk code generator, choose Randomly generate codes and enter the Number of codes. See the step-by-step guide.
Can I create thousands of unique codes for free?
Some apps give a small free allowance: Entafix gives 250 codes a month and Code Bulk 500 codes for the life of the store. Discount Genie's bulk codes need a paid plan, and new stores pay $0.99/mo for the first 3 months on any monthly paid plan.
How do I get bulk unique codes into Klaviyo?
Pick Klaviyo as the Code destination in Discount Genie's Bulk code generator, on a paid plan, and the codes go to a Klaviyo coupon in uploads of up to 1,000 codes. Bulk Discount Code Bot syncs codes to Klaviyo on its $99 Grow plan.
Can I upload my own list of codes to Shopify?
Not in Shopify itself: its export page says you can't import discount codes with CSV files. Discount Genie, Bulk Discount Code Bot, Dyno and Entafix all import your own codes, per each listing checked November 12, 2026.
How many discount codes can one Shopify store have?
20,000,000 unique codes per store, and apps can't raise that limit (Shopify help).
