How to Track a Vessel by Name or MMSI

Find any AIS-equipped vessel by its name or 9-digit MMSI — here's the fast way.

Every AIS-equipped vessel broadcasts a unique MMSI and, usually, a name. If you have either, you can pull its live position in seconds.

By MMSI (most reliable)

The MMSI never has spelling ambiguity. Drop it into our free MMSI lookup tool for the last known position, or open the shareable profile at /vessel/{MMSI}. Programmatically it is one request: GET /v1/vessels/{MMSI} — see the docs.

By name

Names repeat across the fleet, so search returns candidates. Use the vessel directory (filter by type or port) or the live map search box to fly to a match. The API exposes GET /v1/search?name=... for name lookups.
