The state IT and register centres run the e-state's infrastructure and often query data on behalf of other agencies. RIA (the state information-system authority) operates X-Road itself plus the state mailbox and the mandate register; RIK (the registers centre) runs justice and business registers; SMIT serves the interior ministry. Their calls reflect message delivery, authentication and cross-register procedures.
