Embodiments transmit user account updates to a transacting party within an authorization response message without receiving or requesting an inquiry from the transacting party. Both the old account information and the new account information may be included in the authorization response message sent to the transacting party. Accordingly, the updated account information is provided to the transacting party as a part of the transaction processing. The user account update may include a new account identifier assigned to the account, changes to the user information (e.g. name, address, etc.), changes to the information (e.g. expiration date, security code, etc.) associated with the account.
