About Coupon Code Generator
The Coupon Code Generator creates batches of unique discount, promo and voucher codes ready to load into a store, email campaign or spreadsheet.
Choose how many codes you need, how many characters each segment contains, and how many segments join together, then pick a separator to get tidy codes like SAVE-7K9M-2QXP.
You can add a fixed prefix and suffix, which is handy for branding a campaign or tagging codes with a year, and both are automatically uppercased so the output stays consistent.
By default the generator uses a human-friendly character set that drops the easily confused characters — no zero versus letter O, no one versus letter I or L — so customers reading a code off a screen, receipt or sticker are far less likely to mistype it.
If you prefer, you can switch to letters-and-digits, letters only, or digits only.
Every code in a batch is guaranteed unique, and the tool warns you up front if the length and character set cannot supply enough distinct combinations for the quantity you asked for.
Codes are produced with the browser’s cryptographic random number generator, so they are unpredictable rather than sequential, and nothing is uploaded or stored — the whole batch is generated locally and works offline.
Hit Regenerate to roll a fresh set, then copy them all in one click.
FAQ
Are the generated codes guaranteed unique?
Within a single batch, yes — duplicates are filtered out. Across separate batches, very long codes make collisions vanishingly unlikely but are not formally guaranteed.
Why does it skip characters like 0 and O?
The default set leaves out characters people commonly confuse (0/O, 1/I/L) so codes are easier to read aloud and type without errors. You can switch to a full set if you prefer.
How random are the codes?
They are drawn from the browser’s cryptographic random generator, so they are unpredictable rather than sequential, which makes them harder to guess.
