ISO 18422 is officially titled:
“Ships and marine technology — Automatic identification systems (AIS) — AIS binary message application: Messages 6 and 8”
This standard defines the content, format, and usage of binary messages 6 and 8 used within AIS systems for transmitting application-specific information such as:
AIS is a global standard mandated by the IMO (International Maritime Organization), and ISO 18422 ensures that these data packets are universally understood and interoperable.
AIS binary messages are used to transmit critical information between ships, to shore stations, or satellite systems. Without a standardized format, these messages risk being misinterpreted — which could lead to navigation errors, delayed rescue operations, or miscommunication between vessels and port authorities.
ISO 18422 provides:
This standard is essential for AIS equipment manufacturers, shipowners, maritime software developers, and national coast guards.
Organizations implementing ISO 18422 gain:
Adopting ISO 18422 delivers tangible business and operational advantages:
Meet requirements for SOLAS, IMO, and IALA maritime safety communications.
Minimize misinterpretation of critical messages by following standardized binary formats.
Ensure AIS equipment and software are accepted in international ports and on foreign vessels.
Position your AIS products or services as reliable, compliant, and future-ready.
Shorten time-to-market by using pre-approved, ISO-standard binary message templates.
