The Sanctions module checks whether a company’s tax identifier (RUT or CNPJ) appears on major international sanctions lists, including OFAC SDN and the UN Security Council Consolidated List.
Matching is identifier-first and exact only. If the RUT or CNPJ does not appear in a sanctions list, is_sanctioned returns false. No fuzzy name matching is performed — this eliminates false positives by design.

​
What it returns

For a given tax identifier, the API returns:
  • Whether the company appears on any sanctions list (is_sanctioned)
  • Full match details: list name, sanctioned entity name, programs, and matched ID value
  • Which lists were checked and when they were last updated

​

​
Matching logic

The API normalizes both the input identifier and the identifiers stored in the sanctions lists before comparing:
  1. Strips dots, hyphens, slashes, and spaces
  2. Uppercases the result
  3. Compares exactly
Example: 76.354.771-K, 76354771-K, and 76354771K all normalize to 76354771K and will match against each other.

​
Important disclaimer

A result of is_sanctioned: false means the identifier was not found in the checked lists. It does not constitute a comprehensive AML clearance. Your compliance program should define when and how to use this check as part of a broader due diligence process.

​
Data freshness

Lists are refreshed every 24 hours. The lists_updated_at field in every response shows the exact datetime of the last successful refresh per list. If a list failed to load (network issue), its value will be null — you should treat that list as unchecked.
