# Account verification
Validity and status of a card account can be verified.
A response from 3ds service will be required, otherwise a verification required error will be returned.
Account verification is most often (but not always) used as an initial payment in a series of subsequent payments made with the verified card.
In order to later perform a Customer or Merchant initiated payment with the verified card a reference to this initial verification charge will need to be provided. The reference is returned in the card verification response.
