Free Sanctions List Search

1. 11

   Enter the name

   Type the name of a person, company or vessel, the way it is written on the paper in front of you. Capitals and the order of the words do not matter.

2. 22

   We search the 12 lists

   The name is reduced to its words and compared with every record on the Treasury, Commerce and State lists, aliases included.

3. 33

   Read the answer

   You see whether the name is clear, a possible match or a match, and for a match the closest listed name, its list and its programs.

Bulk sanctions screening runs the same search on a whole list with one CSV file.

The free tool searches one name at a time. With a 1Lookup account you upload a CSV file in the dashboard, pick the column that holds the names and download the same file back with the result columns filled in on every row. These rows are invented.

• 3 credits for each completed screening, a clear one included, and nothing for a row that cannot be screened.
• Up to 2 million rows in one CSV file.
• Up to 200 API requests per 10 seconds for each API key, and each account can make up to 1,000 requests a minute in total across all its keys.

The Sanctions Screening API returns the same answer as JSON from one request.

Send the name, with a two-letter country if you like, to the endpoint with your API key. Every completed screening costs 3 credits, a clear one included, and a name that is refused or lists that cannot be read cost 0. The outcome is in classification.outcome and the date of the lists is in classification.list_updated.

To screen every name on a list from your own software, see our Sanctions Screening API.

• A possible match is flagged for review and never passed as a verdict.

  A name that resembles a listed name comes back as a possible match or a match, because a name alone does not show it is the same party.

• Word order, endings and small misspellings do not hide a match.

  Smith, John is John Smith, Inc and LLC are set aside when other words remain, and a longer word still matches a spelling a letter or two off.

• The closest match comes back with its list and programs.

  You see the listed name, the list it is on, such as the Entity List, and the programs, so you know what kind of listing it is.

• The date of the lists is in every answer.

  Each result says how many lists were searched and the day they were updated, so you know how current the check is.
