Avenue 510 uses permanent invite-code attribution, not tracking cookies. Every code is tied to your account. When an agent redeems your code, that customer is permanently attributed to you.
There is no cookie window. There is no expiration date. It does not matter what device or browser the agent uses. As long as they redeem your code, you earn commission for as long as they remain a subscriber.
Your referral link is formatted as https://ave510.com/?via=YOUR_CODE. Share this link with your audience. The /signup page also accepts a manually typed invite code if a referral arrives without the link.
