How it works
The generator builds each code group by randomly selecting characters from the allowed set (letters, digits, or both) using Math.random, then joins groups with your chosen separator. The "exclude ambiguous characters" option removes commonly confused characters — 0 vs O, 1 vs I — to reduce manual entry errors at checkout. Each click generates one fresh code. Regenerate as many times as needed, then record codes in your campaign system before issuing them.
Practical example
You are running a flash sale and need readable promo codes for email recipients. Set 3 groups of 4 characters, dash separator, include both letters and numbers, and exclude ambiguous characters. The result might be "SALE-3KF7-RN2P" — easy to read, unambiguous, and simple to type at checkout. For shorter print codes, reduce to 2 groups of 4.
Frequently asked questions
Answers to common questions about this generator and how it works.
Why exclude ambiguous characters?
It reduces user mistakes by avoiding similar-looking characters like 0 and O, or 1 and I.
Are generated codes guaranteed unique?
No generator can guarantee global uniqueness. Always validate against your database before issuing codes.
What separator is best for users?
Dash separators are usually easiest to read and type in redemption forms.
Can I generate short campaign codes?
Yes. Use fewer groups or shorter group length when you need compact codes for ads or print materials.
