Sign up This coupon code generator creates unique coupon code strings, also called promo codes, discount codes, or voucher codes depending on your platform and audience, the kind you'd load into your store's discount system to run a sale, referral, or loyalty promotion. Whether you searched for a coupon code generator, promo code generator, discount code generator, or voucher code generator, this tool covers all of those use cases since they all work the same way mechanically: a code string tied to a discount rule. It generates the code text itself; it does not create a working, redeemable discount code, promo code, or voucher for a store you don't own or manage. If you're a shopper looking for an active discount code or free voucher code for a specific retailer, this isn't the right tool, it's built for merchants setting up their own promotions.
A coupon code's format affects more than aesthetics, and the same rules apply whether you're calling it a coupon code, promo code, discount code, or voucher code in your campaign. Short, memorable codes (SAVE20, WELCOME10) work well for broad, single-campaign promotions shared in email or social, since customers need to recall or retype them. Longer, randomized alphanumeric codes generated through a discount code generator or voucher code generator work better for single-use, per-customer codes, like referral rewards or fraud-sensitive campaigns, since they can't be easily guessed or shared publicly.
A few structural choices worth deciding before you generate a batch: whether codes are single-use or reusable across multiple customers, whether they expire on a fixed date or a rolling window from first use, and whether you're layering a prefix (SUMMER-XXXX) to make batch tracking and reporting easier once codes are live. All of these are configuration decisions made in your store's discount system after import, but planning the code structure up front avoids reissuing a batch later.
Reused, leaked, or guessed coupon codes are one of the most common sources of promo code abuse. Sequential or short numeric codes generated by any free coupon code generator are especially vulnerable, since they can be iterated automatically. If a campaign is high-value or public-facing (a viral social post, an affiliate link), generate longer alphanumeric codes and set a redemption limit per code in your store platform rather than relying on the code's obscurity alone.

A coupon code is a short unique string that customers enter at checkout to receive a discount, free shipping, or a special offer. Unlike gift cards, coupon codes reduce the order total rather than drawing from a stored balance. They are used to drive promotions, reward loyalty, and reduce cart abandonment.
Enter the code length and how many codes you want, then pick a character type: Alphanumeric, Numeric, Alphabet, or All Caps. Click Generate and your codes appear instantly. Use the More Actions section to add a prefix, suffix, or custom code pattern. Export the full list as a CSV file and import it into your store.
Alphanumeric uses both letters and numbers (for example SUMMER24). Numeric uses digits only (for example 95486358). Alphabet uses mixed-case letters (for example giftcard). All Caps uses uppercase letters only (for example TAARRUKY). Most eCommerce platforms accept alphanumeric or all-caps codes, which are easier for customers to read and type.
Yes. Open the More Actions panel to set a prefix and a suffix. Every generated code will include them automatically. A prefix like SALE and a suffix like 25 turns a code like ABCD1234 into SALEABCD123425. This is useful for organising codes by campaign, date, or discount tier.
The code pattern lets you control the exact format of each code using # as a placeholder for a random character. Any character that is not # is inserted literally into every code. For example the pattern ####-####-#### produces codes like ABCD-1234-EFGH, with fixed hyphens between character groups.
Click Export to save your codes as a CSV file. Then import them into your eCommerce platform using the built-in coupon import tool. Clicking Import to opens your connected platform directly. Shopify, BigCommerce, Shopify Plus, Salesforce Commerce Cloud, and WooCommerce are all supported. For automated coupon creation, scheduling, and analytics, the 99minds platform handles this end-to-end.
Yes, largely. "Coupon code," "promo code," "discount code," and "voucher code" all describe the same mechanism: a text string that applies a discount at checkout. Different platforms and regions favor different terms, Shopify and BigCommerce commonly say "discount code," email marketing often says "promo code," UK and EU retailers commonly say "voucher code," but functionally they work the same way in this coupon code generator and in your store's discount system.
A coupon code applies a discount, a percentage off, a fixed amount off, or free shipping, without carrying stored monetary value of its own. A gift card code represents an actual dollar balance that can be spent like currency. Coupons typically expire after a campaign; gift card balances persist until spent or the card itself expires. If you need stored-value codes, use the gift card code generator instead.
No. Coupon codes only function within the specific store's discount system they're created in. This tool generates the code string; it has to be loaded into your own store's platform (Shopify, BigCommerce, WooCommerce, Salesforce) with a discount rule attached before it does anything.
Export the generated batch as a CSV, then upload it through your store platform's bulk discount import feature. Each platform has a slightly different import format; 99minds' full coupon management module handles this import and the discount rule setup together if you're issuing coupons regularly rather than as a one-off.
No, generation happens locally in your browser. Codes are only stored if you export them and later import them into a connected platform account.
This coupon code generator produces the code string only. For merchants running recurring promotions, 99minds' coupon management module handles code generation, discount rules, expiration, usage limits, and redemption reporting in one place, the same system behind the standalone tool here.
