What is the OFAC list update process?

OFAC updates the SDN list on a rolling basis — typically daily during business days, with occasional intraday updates for urgent designations. There is no fixed schedule. A new designation is enforceable the moment it is published.

Sync frequency matters

If your screening tool syncs weekly and a designation happens on Tuesday, you may process prohibited transactions for 5 days before the new entry is in your screening database. SanctionsAI syncs hourly — the fastest practical frequency.
