Random Coupon Code Generator

Used by developers, writers, and creators worldwide.

A random coupon code generator produces batches of unique, hard-to-guess promo codes for campaigns, giveaways, loyalty rewards, and testing. Each code is built from an unambiguous character set that deliberately omits easily-confused characters like O and 0 or I and 1, so customers can read and type them without errors. Set the length, choose how many you need, and add an optional prefix like SAVE or WELCOME to brand the campaign and make codes easy to recognise. The result is a clean list you can paste into your e-commerce platform, a spreadsheet, or a test fixture. Generate a batch, copy it, and import the codes wherever your promotion lives.

FAQ

are the generated coupon codes unique

With a reasonable length, codes drawn from this character set are extremely unlikely to collide within a batch. For mission-critical uniqueness, generate more than you need and de-duplicate, or check each code against your store before activating it.

why does the code skip letters like o and i

The character set deliberately omits ambiguous characters such as O, 0, I, and 1 so customers reading a code from an email or a printed voucher do not mistype it. Clear codes mean fewer failed redemptions and support tickets.

can i add a prefix to my codes

Yes — add a short prefix like SAVE or SUMMER and every code is branded with it, for example SAVE-7K2M9XQF. A prefix makes a campaign instantly recognisable and lets you group codes by promotion.
