Coinbase Referral Code 3KMZM83 - $10 BTC Bonus 2026
The Coinbase referral code is 3KMZM83. Sign up through coinbase.com/join/3KMZM83, make a qualifying purchase, and the referral bonus lands in your account, typically about $10 in BTC for US users. Coinbase’s own terms no longer publish one flat figure: «The amount of the bonus varies based on country» (Coinbase referral terms, retrieved 20 August 2026), so the exact amount for your region is shown on the invite screen.
Key takeaways
The bonus requires a qualifying purchase made with a bank transfer, debit or credit card. Purchases on Coinbase Advanced and Coinbase Prime do not qualify.
The purchase must happen within 90 days of the new account becoming trade-eligible.
Payouts arrive in 5 to 15 days after qualification (15 to 30 days in Canada, where a CA$30 minimum trade also applies).
Coinbase’s terms prohibit sending referral links to residents of the United Kingdom and Turkey.
How the referral works
Coinbase’s program is deliberately simple compared to the task-chain bonuses on offshore exchanges: one qualifying purchase, one bonus, paid in crypto or local currency. There is no wagering-style volume requirement and no lock-up beyond the payout window. The trade-off is size; the reward is a small fixed amount, not a four-figure cap. For most users the referral bonus is a welcome extra rather than a reason to choose the platform.
Why pick Coinbase at all
Coinbase is the largest US-listed exchange (NASDAQ: COIN), with beginner-friendly onboarding and a strong regulatory standing across the US and, through its MiCA licence, the EEA. In our MiCA exchange comparison it sits among the top regulated venues. Fees on the simple buy flow are higher than on Coinbase Advanced, so cost-sensitive users should graduate to Advanced after the bonus qualifies.

Open coinbase.com/join/3KMZM83 and create the account.
Complete identity verification, and note the bonus amount shown for your country on the invite screen.
Make a qualifying purchase (bank transfer, debit or credit card) within 90 days.
The bonus arrives within 5 to 15 days of qualifying (longer in Canada).
