Sanctions + FATF

Compliance risk score

Bank-BIC sanctions screening (OFAC, EU, UN) + FATF + SEPA + VoP reachability, distilled into a 0-100 risk score.

14 November 2026: Switzerland stops processing unstructured addresses

  • SIX no longer processes payments whose address fails the structured or hybrid rules.
  • The Eurosystem and the EPC switch the same weekend.
  • Swift suspended its own date on 27 August 2026.

POST /v1/address/check says for free whether an address passes the Swiss, HVPS+ or Fedwire rules, naming the document; the file audit takes a whole workbook.
