Coupon Code Generator
Generate batches of unique coupon or discount codes.
Codes for a promotion
Running a promotion often needs a batch of unique codes — one per customer, or a set of single-use discounts. This generates batches of unique codes to your specification, so you have the codes a campaign needs without inventing them one by one.
Set the format and quantity to generate codes.
What makes coupon codes work well
Good promotional codes balance a few practical considerations. Uniqueness matters when each code should be used once, so the batch must contain no duplicates. The format is a trade-off: codes need to be long and varied enough that people cannot simply guess valid ones and get discounts they were not given, but short and clear enough to type without errors — avoiding characters that look alike, like the letter O and zero, reduces mistakes. A readable, memorable style suits public promo codes, while single-use codes can be more random. Generating a clean batch to a chosen format handles the uniqueness and consistency automatically, which is exactly the tedious, error-prone part of preparing a code-based promotion by hand, letting you focus on the campaign rather than the codes.
