We ask our users interested in buying and selling bitcoin in the Blockchain Wallet to verify their identities in order to offer a seamless and high-quality experience. Additionally, as part of our regulatory obligation to prevent money laundering, terrorist financing, and other types of financial crime, Blockchain is required to obtain and verify certain identifiable information about our customers. You can learn more about identity verification here.
Identity verification is not required to use the Blockchain wallet. It is only required for buying/selling bitcoin and exchanging between cryptocurrencies within the wallet.
