'''Communications data''' (sometimes referred to as '''traffic data''' or [metadata](/source/metadata)) concerns information about communication.<ref>{{Cite journal |title=Briefing Note: Why Communications Data (Metadata) Matter |url=https://www.bigbrotherwatch.org.uk/wp-content/uploads/2014/07/Communications-Data-Briefing.pdf |journal=Big Brother Watch}}</ref>

Communications data is a part of a message that should be distinguished from the content of the message. It contains data on the communication's origin, destination, route, time, date, size, duration, or type of underlying service.<ref>[http://conventions.coe.int/Treaty/EN/Treaties/Html/185.htm Convention on Cybercrime]. Artikel 1(d): "traffic data" means any computer data relating to a communication by means of a computer system, generated by a computer system that formed a part in the chain of communication, indicating the communication’s origin, destination, route, time, date, size, duration, or type of underlying service.</ref>
