The **Registration Data** section is designed for entering vessel information that will be transmitted to the **AIS** if it is connected and capable of receiving **VSD** and **SSD** messages.

```{important}
Vessel registration data must exactly match the data in the vessel's documents. Incorrectly entered data may cause errors in the AIS system and violate international convention requirements.
