The '''Automatic Transmitter Identification System''' ('''ATIS''') is a [[marine VHF radio]] system used and mandated on navigable inland [[waterway]]s in Europe for identifying the ship or vessel that made a radio transmission. The identity of the vessel is sent digitally immediately after the ship's radio operator has finished talking and releases their transceiver's [[push-to-talk]] button. This contrasts to the [[Automatic identification system]](AIS) used globally on ships that transmit continuously. A short post-transmission message is sent by the radio with the vessel identity and is in the form of an encoded [[call sign]] or [[Maritime Mobile Service Identity]], starting with number "9" and the three country-specific [[maritime identification digits]].
