Coinbase Invite Code 3KMZM83 (July 2026)
The Coinbase invite code is 3KMZM83. Enter it through the claim link and the offer — ~$10 in BTC — is applied automatically (it's the platform's advertised maximum). Listed July 2026.
What you get with the 3KMZM83 code
Coinbase's refer-a-friend program pays a reward in Bitcoin when a new user signs up via a referral and completes a qualifying purchase. The amount is not fixed — Coinbase describes a randomized range, and the value depends on your region, account type and any active promotion. Use code 3KMZM83 at signup; this goes in the referral/invite field, not a fee-discount field.
Coinbase bonus: pros & cons
Pros
- Publicly listed (Nasdaq: COIN) with audited financials and US state money-transmitter licenses — high regulatory accountability
- Coinbase One removes trading fees for a flat monthly cost — suits active retail traders
- Non-custodial Coinbase Wallet integrates with the main account for easy self-custody
- Proof-of-reserves published; USDC fully backed and regulated via Circle
Cons
- Standard retail fees are high — ~0.6% taker on small orders via the consumer app (Advanced reduces this, but the app hides the structure)
- No perpetual futures for most international retail users; derivatives access is jurisdiction-limited
- Criticized for account-access lockouts and slow support during account recovery
How to claim your Coinbase bonus in 3 steps
Open the sign-up page
Use the claim button — it opens Coinbase registration with code 3KMZM83 attached. If you arrived another way, paste 3KMZM83 into the referral field before submitting.
Verify your identity (KYC)
Coinbase requires identity verification before you can trade and before any welcome tasks become available.
Complete the welcome tasks
Open Coinbase's rewards hub to see which deposit and volume tasks are live in your region — these determine how much of the "~$10 in BTC" maximum you actually receive.
Before you sign up
- Check that Coinbase is available in your country and what verification it asks for.
- Enter the code at registration: exchange referral fields only exist when you first create the account.
- Confirm the current bonus and its conditions on Coinbase's own site before depositing — figures change.

Coinbase bonus — frequently asked questions
How much is the Coinbase referral reward?
It's a Bitcoin reward paid after a referred user makes a qualifying purchase, and it's not guaranteed or fixed — Coinbase has historically offered around $10 per successful referral plus region-dependent new-user incentives. Treat any large advertised figure with caution.
Does Coinbase work outside the US?
Yes, in 100+ countries — but specific products (some staking, advanced trading) vary by region due to local regulation.
Is there a Coinbase invite code?
Yes — 3KMZM83 doubles as the Coinbase invite code. Enter it in the referral/invite code field when you create your account; there isn't a separate one.
Is the Coinbase referral code 3KMZM83 legit?
Yes. 3KMZM83 is Coinbase's own referral code, entered in the official Coinbase signup — it's free, never asks for your password, and can only add the discount or rewards, not remove them. CryptoBonusKing earns a commission paid by Coinbase when you sign up; it never changes what you receive.
