Coupon Code Generator

This free coupon code generator creates batches of unique, hard-to-guess promo codes for sales, email campaigns, gift cards and loyalty programs. Add a prefix like SAVE and an optional suffix, pick the length and character set, or drop in a pattern like ####-####-#### where each # becomes a random character and everything else stays literal. The no-ambiguous set drops easily-confused characters like O and 0 so codes are easy to read and type, and you can paste your own custom character set instead. Generate up to 100,000 at once, watch a live preview, then copy them or export as a .txt list or .csv sheet. Codes use your browser's secure random source, are de-duplicated within each batch, and the tool warns you when your settings can't produce that many unique codes.
