Vessel Information Verification Service (VIVS)

The VIVS is a NAVCEN web service that allows you to retrieve a vessel’s broadcasted AIS static data, i.e Maritime Mobile Service Identity (MMSI), call sign, name, number, dimensions, draft, type, and positioning source, received within our NAIS coverage area*. Search result(s) will also highlight any discrepancies of this data with corresponding official data from the vessel’s Radio Ship Station License (via FCC ULS) and/or Certificate of Documentation (via USCG PSIX)**.
