What is verification tier?

The level of identity checks you have completed on an exchange, which sets your deposit, trading, and withdrawal limits.

Exchanges do not run one identity check, they run a ladder of them, and where you stand on that ladder controls what the account can do. The tiers are the venue's own construction, so the names, the thresholds, and the documents required differ from one to the next.

The error that causes real problems is depositing first and verifying later. Upgrading a tier takes time, and it happens while your money is already inside.

How it works

A first tier typically requires an email address and a password and permits little more than looking around. A second requires a government identity document and a selfie check, and unlocks ordinary fiat deposits and trading. A third asks for proof of address, and a fourth, applied to larger accounts, asks for source of funds or source of wealth evidence such as payslips, tax returns, or a sale contract.

The escalation is driven by regulation rather than by exchange preference. Anti-money-laundering rules require enhanced due diligence proportionate to risk, and account size is one of the factors that triggers it.

Three properties matter to a user. Limits are usually stated separately for fiat deposits, crypto withdrawals, and card purchases, so clearing one does not clear the others. Verification can be requested retroactively on an account that already passed a lower tier, typically when a large transaction arrives. And review times vary from minutes for automated document checks to weeks where a human reviews source of funds evidence.

Each exchange publishes its own tier table in its help center, and that page is the only authoritative source for the current thresholds.

Example

Illustrative. You verify with an identity document, which clears a daily withdrawal limit of $10,000, and deposit $60,000 intending to buy and move it to a hardware wallet.

The purchase succeeds because trading is not capped at the same level. The withdrawal is not: at $10,000 a day it takes six days to move, or you upgrade to the next tier by supplying proof of address and source of funds. That review takes an unpredictable number of days, during which your position is on the exchange. Had you checked the withdrawal limit first, the entire problem would have been visible before the deposit.

Why it matters when you buy

The tier you need is a function of the amount you intend to move, not the amount you intend to buy, and the two limits are different numbers on most venues. Check the withdrawal limit at your tier before funding, and complete the upgrade first if it falls short. The exchange directory covers verification requirements by venue, and the guide on verification tiers and limits goes through the documents each level asks for.

Questions

Why does the exchange want my source of funds?

Because anti-money-laundering rules require enhanced checks on higher-risk or higher-value relationships. It applies to banks in the same way, and refusing generally means the account stays capped at a lower tier.

How long does verification take?

Automated document checks often clear in minutes. Manual reviews of address or source of funds evidence take days and sometimes weeks, and the queue lengthens during periods of heavy signups.

Can I trade without verifying?

Rarely, and only on venues that do not serve regulated markets. Any exchange offering fiat deposits in a jurisdiction RampAtlas tracks will require identity verification before you can fund an account.
