Identification is the act of confirming that the person who registers to use a service is, in fact, that person. In most cases, it is confirmed by checking that the name, birth date, and address match those on a driver's license or passport.

BitFlyer uses multiple methods to authenticate individuals. By using multiple methods of identification, we can prevent third parties from pretending to be you. Thank you for your cooperation with these methods.

If you want to change the information you have submitted, this cannot be done through the web site. We will change your information after you call bitFlyer and confirm your identity on the telephone. We take this precaution because in a situation where users can freely change their information after it has been registered, a third party who illicitly accessed an account could overwrite this information and hijack the account.
