Why crypto exchanges request identity documents
US crypto exchanges request identity documents because FinCEN anti-money laundering rules require customer verification to open an account or move money.

The requirement is federal law, not an exchange's own preference. It applies to exchanges that serve US customers.
Why do exchanges ask for ID?
The rule comes from the Bank Secrecy Act, which FinCEN enforces. FinCEN treats a crypto exchange that serves US customers as a money services business. That status requires an anti-money laundering program with customer identity checks.
Which crypto actions require verification?
Verification usually starts when you open an account. It follows your activity when you trade or move money, while self-custody wallets and peer-to-peer trades without an exchange generally avoid these checks.
- Opening an account
- Trading crypto for US dollars
- Depositing or withdrawing dollars
- Sending crypto to an outside wallet through the exchange
What information do exchanges collect?
FinCEN's Customer Identification Program rule sets the details an exchange must collect. The Customer Identification Program is a required set of checks that ties your account to official records.
What if I refuse verification?
An unverified account can be restricted from trading, deposits, or withdrawals until the exchange confirms who you are. The exchange must protect your data, but it can share your identity records with FinCEN and law enforcement.
Frequently asked questions
Usually no. A decentralized exchange runs on smart contracts rather than a company that collects documents. Some front ends block US users.
Federal anti-money laundering rules generally require exchanges to keep customer identification records for five years after the account closes.
No. A VPN hides your network location, but the exchange still checks your identity when you open or use the account.
Exchanges usually reject an expired document and ask for a current one. You may need to upload a new photo and wait for review.
