Shopify lets you create discount codes, but its native tools aren’t built for generating them in bulk. If you need hundreds or thousands of unique codes – for a loyalty campaign, influencer program, or one-code-per-customer promotion – you’ll quickly hit the limits of what Shopify can do on its own.
The solution is to use Shopify’s redeem codes system, which lets a single discount have multiple unique codes. Regios Discounts gives you a dedicated interface to generate, import, and manage those codes at scale – without duplicating your discount logic for every code.
Here’s how it works.
The problem with Shopify’s native discount code tools
When most merchants need unique codes for a campaign, their instinct is to create a separate discount for each one. That gets unmanageable fast – and you’re stuck maintaining dozens of identical discounts with different codes.
Shopify actually supports a better model: one discount with multiple redeem codes. Each code is unique, but they all share the same underlying logic. You define the discount once, and attach as many codes as you need.
The catch is that Shopify’s admin UI doesn’t make this easy to do at scale. Adding codes in bulk requires using the API, which is where Regios Discounts comes in.
Three ways to add codes in bulk
Generate random codes
If you need a set of unique codes and don’t care what they look like, random generation is the fastest option. Specify how many codes you need, choose a length and format (letters only, alphanumeric, with a prefix, etc.), and the app generates and uploads them automatically.
Import from CSV
If you already have a list of codes – from a spreadsheet, another tool, or a customer list – you can import them directly. Drop in a CSV, and the app reads the codes and uploads them to the discount.
You can also apply a prefix or suffix during import, which is useful for adding a campaign identifier to codes you’ve already generated elsewhere.
Enter codes manually
For small sets of specific codes, you can type or paste them directly, separated by commas. Same prefix/suffix options apply.
What to expect on upload time
Large uploads take time – but that’s due to how Shopify’s API works, not the app. Shopify processes redeem codes in batches and rate limits how quickly those batches can be submitted.
Regios Discounts queues up as many batches as needed to fulfill your request and handles them automatically in the background. You can close the window at any time and come back to check progress.
Managing codes after upload
Once codes are uploaded, the redeem codes page gives you filtering and sorting tools to manage them:
- Sort by creation date or code name
- Filter by number of times used
- Search for specific codes by name
You can also export your full code list to a CSV at any time – useful for distributing codes to customers, tracking usage, or syncing with an email platform.
A few things to know before you start
You can’t rename the discount after adding codes. Shopify locks the base discount name once redeem codes are attached, even if you delete them later. Make sure you’re happy with the name before uploading.
“Limit number of uses” applies per code, not per discount. If you set a usage limit of 1, each individual code can be used once – not the discount as a whole. This is usually what you want for single-use codes.
Codes must be unique across your store. If a code already exists in Shopify (from another app, another discount, or a previous campaign), it can’t be imported again. There’s no workaround for this – it’s a Shopify constraint.
The short version
Shopify supports multiple redeem codes per discount, but doesn’t make bulk generation easy natively. Regios Discounts lets you generate random codes, import from CSV, or enter them manually – all attached to a single discount you configure once. Upload runs in the background, and you can export the full list at any time.
