It comes ahead of tough new rules on the advertising of digital asset products in the country.
If a customer fails to complete the tasks successfully, they will be prevented from trading with their crypto account.
Coinbase said the changes were made "to ensure we are meeting UK investor protection standards, which require our users to have the necessary knowledge to make informed investment decisions."
"We do not expect this to impact user activity in the UK and as always our customer service team is on hand to help with any queries," George Tucker, U.K. general manager of Crypto.com, told CNBC via email.
"As an authorised Electronic Money Institution and registered cryptoasset business in the U.K., Crypto.com supports and complies with the FCA's rules and will continue to work with the regulator as we expand our product offering here," Tucker added.
