Keep spoken codes simple
If customers will say the code on a podcast, at an event, or in a store, use 6–8 readable characters and remove 0/O and 1/I/L.
1 Configure your codes
Pick a format, add an optional campaign prefix, and paste customer names or IDs if you want an assignment-ready CSV.
Choose a preset
Letters and numbers only. We add the separator.
One per line, up to 500 rows. When present, the tool generates one code per row and ignores the quantity field. Batches over 500 are rejected rather than silently truncated. This data stays in your browser.
Use letters, numbers, underscores, or hyphens. Creates links such as example.com/join?ref=LAUNCH-ABC123.

Ready. Generation uses your browser's cryptographic random-number source when available.
This generator creates shareable identifiers, not secrets. Do not use them as passwords, access tokens, gift-card claim tokens, or the only check for cash-value redemptions. Authenticate redemptions, make high-value claims one-time, rate-limit attempts, and review duplicate or self-referrals. For unique links, referral attribution, reward delivery, and fraud review in one system, use a KickoffLabs referral rewards campaign.
2 Pick a code format people can actually share
Use a prefix for operations
A campaign prefix such as LAUNCH or VIP makes exports easier to audit. Do not put private customer data inside the code itself.
Pair every code with a link
Codes work offline. Links remove typing online. Give customers both and let the sharing context decide.

3 Referral code generator FAQ
Is this referral code generator free?
Yes. You can generate up to 500 codes per batch, copy them, and download a CSV without creating an account.
Are the generated referral codes guaranteed to be unique?
The tool checks every code inside the current batch and regenerates collisions. You must still check new batches against codes already stored in your own database or referral platform.
Does KickoffLabs receive the names or emails I paste?
No. Generation happens in your browser. The page does not send pasted participant data to KickoffLabs.
How long should a referral code be?
Six to eight random characters is a practical default for many lists when you use a broad alphabet. Use longer codes for very large programs, and always enforce uniqueness in your system of record.
What is the difference between a referral code and a referral link?
A referral code must be entered or spoken. A referral link carries the identifier in the URL, so attribution can happen after a click. Strong programs usually offer both.
Can this tool track referrals or issue rewards?
No. It creates code and link assets only. KickoffLabs can run the full program: capture participants, issue unique referral links, attribute signups, manage rewards, and review suspicious activity.
