About the Coupon Code Generator
Generates random coupon or promo codes in bulk, built from segments of letters and numbers with an optional prefix, using your browser's cryptographically secure random source.
Marketers use it to generate a batch of unique promo codes for a campaign in seconds, while small business owners use it for one-off discount codes without needing a full e-commerce platform. It's one of many free generators on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

Frequently asked questions
Quick answers to common questions about the Coupon Code Generator.
What does the Coupon Code Generator do?
It generates one or more random coupon or promo codes, built from segments of letters and numbers with an optional prefix.
Is the Coupon Code Generator free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Is my input safe when I use this tool?
Yes. Every code is generated entirely on your own device — nothing is sent to a server, and codes aren't recorded anywhere.
Are the codes cryptographically secure?
Yes. Every character is chosen using your browser's crypto.getRandomValues API, not Math.random() or another predictable formula.
What does "Avoid confusing characters" do?
It removes characters that are easy to misread or mistype, such as 0 (zero) and O (letter), or 1 (one), I (capital i) and l (lowercase L).
Does this tool check codes against my store or database?
No. It only generates random codes locally in your browser — you're responsible for adding them to your own coupon or discount system.
Can I use the Coupon Code Generator on my phone?
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
Does the Coupon Code Generator have any limitations?
It generates up to 500 codes per batch, with 1 to 6 segments of 2 to 10 characters each — it doesn't check for accidental duplicate codes across separate batches.
