AIS is event-driven. No recent transmission does not imply vessel unavailability.

Vessel Lookup & AIS Intelligence
Operational vessel identity, AIS signal and latest-position context for commercial assessment, not navigation.
Vessel Monitor
Vessel lookup
Search MMSI, IMO, vessel name or call sign with local identity, AIS cache and a short event-driven capture window.
Operational information
Vessel identity
Search by MMSI, IMO, vessel name or call sign. Available identity information includes its documented source.
AIS signal
A recent transmission or a cached observation may be available. Vessel identity alone does not establish its current position.
Position timestamp
The time shown belongs to the available AIS position. It is separate from the identity record verification date.
FAQ
Frequently asked questions
What is MMSI?
MMSI is the identifier of a maritime station that may appear in AIS transmissions.
What is IMO?
IMO is a vessel identification number that is more stable than a commercial vessel name.
Why might there be no recent AIS position?
AIS depends on transmission, coverage, provider and capture window. No signal does not confirm vessel unavailability.
