How to Check a Vessel for Sanctions
Use this free vessel sanctions check to look up a ship by name or IMO number. You can search all supported lists at once or select a specific list.
- Enter the vessel name or IMO number. Type the ship's name or its 7-digit IMO number into the search field.
- Choose the sanctions lists. Keep "All lists" selected to search every supported list, or select OFAC, UK, Canada, Australia or Switzerland.
- Review the potential matches. Check the match score, sanctions list, sanctions program and vessel details, and compare the identifiers with the ship you are checking.
Search by IMO Number, Not Just the Vessel Name
A vessel's name can change, but its IMO number stays the same throughout its life. For this reason, searching by IMO number is often the best starting point for a ship sanctions check.
The IMO number is a unique, 7-digit identifier assigned to a ship. The last digit is a check digit used to validate the number. The identifier remains unchanged when the ship is renamed, sold or reflagged. It is also permanently marked on the hull.
Vessel names are less reliable identifiers because ships can operate under different names over time. Sanctioned tankers are often renamed and reflagged, which is one reason the shadow fleet is hard to track. Sanctions lists may include a vessel's former names as aliases, shown as "a.k.a." (also known as).
The Maritime Mobile Service Identity (MMSI) and call sign are also useful details, but they are tied to flag registration and can change when a ship changes flag. They are therefore weaker identifiers for confirming a vessel's identity across different records.
Where to Find a Vessel's IMO Number
Check the ship's certificates or the bill of lading. You can also look up the vessel in Equasis, a free ship information database that requires registration. Once you have the IMO number, enter it in the search above.
What the Search Result Shows
Each result provides vessel details that help you compare the entry with the ship you are checking. Depending on the information published in the source list, a result can include:
- Vessel name and aliases: The name listed in the record, along with former names or other aliases.
- IMO number: The vessel's permanent 7-digit identifier, where available.
- MMSI and call sign: Additional identifiers recorded in the listing.
- Flag and former flags: The vessel's current listed flag and any former flags included in the record.
- Vessel type: The ship's recorded type, such as an oil tanker or LPG tanker.
- Sanctions list: The source list containing the entry.
- Sanctions program: The program associated with the entry, where provided.
- Linked owner or operator: An owner or operator named in the list, when the source record identifies one.
Example Entry From the OFAC SDN List
FENGSHUN, a.k.a. VENUS 7 – LPG tanker – flag: Eswatini – IMO 9007386 – MMSI 374350000 – program: SDGT – linked to KAI HENG LONG GLOBAL ENERGY LIMITED.
The same ship is also listed as VENUS 7. The IMO number ties both names to one vessel.
What Does the Match Score Mean?
The match score indicates how closely a search result matches the information you entered. A match on the IMO number is a strong signal because that identifier is assigned to the ship for life. A match on the vessel name alone is a lead to verify, not proof that the entry refers to the same vessel. Compare the IMO number and flag before drawing conclusions.
Which Sanctions Lists This Search Covers
One search checks all of the following lists at once, so you do not need to visit each regulator's website separately.
OFAC SDN List (United States)
The OFAC Specially Designated Nationals and Blocked Persons (SDN) List includes vessels designated under programs such as Iran, Russia, North Korea, Venezuela and counter-terrorism (SDGT). Vessel entries usually include the IMO number, call sign, flag and vessel type.
UK Sanctions List
