The Data Mailbox Information System is a public administration information system. A data mailbox enables you to send and/or receive electronic documents to/from public authorities, such as courts, police or administrative bodies, free of charge.
Communication via data mailboxes replaces the classical method of delivery by letter because of the Data Mailbox Act which has made the paper and electronic versions of sent documents equal. Public authorities and legal entities registered in the Commercial Register have a data mailbox set up automatically, everyone else has to apply for its setup.
