Welcome to the United States Coast Guard
Vessel Information Verification Service

The VIVS is a web application in which commercial vessel owners/operators can verify the accuracy of their Automatic Identification System (AIS) broadcasted information per 46 U.S. Code Chapter 125. This includes the vessel name, call sign, vessel type, Maritime Mobile Service Identity (MMSI), length, and beam.
The Vessel Information Verification Service (VIVS) contains vessel specific information derived from a variety of approved sources. The information contained in VIVS represents a daily (excluding weekends and holidays) snapshot of Freedom of Information Act (FOIA) data on U.S. flag vessels and foreign vessels operating in U.S. waters. Information on Coast Guard and Port Partner vessels is considered privileged information and is precluded from the VIVS system. For more information on the data returned through VIVS, please click here.


The U.S. Coast Guard and the United States is not liable for any loss, damage, or harm resulting from the use of information contained in this database, or for any reliance on its accuracy, completeness, or timeliness.
Unauthorized attempts to upload or change information on this web site are strictly prohibited and may be punishable under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act.

VIVS only checks static AIS data. Operators are reminded to regularly verify the validity of their dynamic (voyage specific) data before and during each voyage.
