- Tier 0 - you can look around but you can't deposit, withdraw or make any trades. You are required to provide your email address.
- Tier 1 - you can deposit and withdraw in digital currency only. Trading, however, is enabled in digital as well as fiat currencies. You are required to provide your full name, date of birth, country and phone number.
- Tier 2 - you can deposit, withdraw and trade in digital currency, and depending on your country of residence, fiat currency funding may be accessible to you. Bank deposits and withdrawals are available to clients in some areas at this tier and higher. You are required to provide your address.
- Tier 3 - fiat currency funding is available to Tier 3 clients and funding limits are much higher than Tier 2. You are required to upload a valid Government ID and a recent proof of residence (can be uploaded under 'Get Verified' tab of your Kraken account).
- Tier 4 - like Tier 3 but with even higher funding limits. There are both individual and corporate Tier 4 accounts. The required documents for Tier 4 individual accounts include a signed application form and KYC documents. The required documents for Tier 4 corporate accounts include a signed application form, a trade register extract, a certificate of incorporation, bylaws, an organizational chart, a written AML policy (if applicable) and KYC documents for Ultimate Beneficial Owners (UBOs).
I am Tier 1, that is all I need. Always deposit/withdraw via BTC. Deposit coins, first SELL all coins (after which you have cash), use all the cash to re-buy coins (99% chance new coins won't be associated with your name), make BTC withdrawal from Kraken to Coinbase/Circle.
