Free OFAC SDN Search
Run an OFAC SDN search on any name, company, or crypto address — free, no signup. Results come from the live SDN publication stream (re-ingested every 15 minutes) plus the other sanctions and crime lists CompliAPI screens, and every match names the list it was found on.
This is not the official OFAC tool — for authoritative confirmation of a designation, use OFAC's Sanctions List Search.
What this SDN list search covers
The primary source is the US OFAC Specially Designated Nationals (SDN) list, re-ingested from Treasury's publication stream every 15 minutes, and OFAC's separate Consolidated (non-SDN) list — the two are different lists with different legal consequences, a distinction our SDN vs non-SDN guide walks through. The same search also checks every other list CompliAPI screens — EU, UK, French, Japanese, and Israeli sanctions registers plus crime-intelligence sources — and labels each match with its list, so an SDN hit is always distinguishable.
The search matches the names and aliases recorded on listed identifiers — crypto addresses, email addresses, websites, and government ID numbers such as passports and registration numbers — as well as the identifier values themselves and OFAC-sanctioned countries. A party listed with no such identifier on file will not appear here; for definitive coverage, check the official tool.
Reading your SDN check results
An exact match means the value you searched equals a listed identifier or a listed party's name. Anything else is a partial match, ranked by trigram similarity — name fragments and substrings will match, but the search is not typo-tolerant beyond that, so try alternate spellings and name orders (OFAC records individuals as "LASTNAME, Firstname").
Every result carries its list attribution: which list, its type (sanctions, crime intelligence, or risk exposure), and the OFAC sanctions program where recorded — the details a compliance officer needs to write down. Entries marked Delisted have been removed from their source list; recent removals are tracked here.
A hit is a starting point, not a determination: name matches produce false positives, and a potential SDN match obligates you to verify the identity against the official record (linked on each result) before blocking or reporting. A clear result is equally not a clearance — it means no match on the lists searched, nothing more.
Searching crypto addresses against the SDN list
OFAC designates digital-currency addresses alongside names — Bitcoin, Ethereum, Tron, and more — but the official search treats them as ordinary ID fields. Here, addresses are first-class: paste any address and it is matched against every listed address on the SDN list and the other screened lists, including FBI-attributed Lazarus Group addresses and ransomware payment addresses. Sanctioned-wallet exposure is one of the fastest-moving parts of OFAC enforcement; our guide to OFAC-sanctioned crypto wallets covers how addresses end up designated and what a match means.
Need to run SDN checks automatically?
This page is the manual version of what the CompliAPI screening API does programmatically: exact-match screening with a sanctioned / flagged verdict, an audit trail of every check, and the same list attribution — one authenticated GET request per identifier. The free tier includes 10,000 requests a month.

}Frequently asked questions
Is this the official OFAC sanctions search?
No. The official tool is OFAC's Sanctions List Search at sanctionssearch.ofac.treas.gov, and it remains the authoritative place to confirm a designation. This search runs on CompliAPI's independently maintained copy of the SDN publication stream, refreshed every 15 minutes, and adds capabilities the official tool lacks — crypto-address lookup and attribution across additional sanctions and crime lists.
Do you store what I search for?
No. This free search is unauthenticated and is deliberately excluded from request logging — searched names and addresses are not stored. Paid API screening calls are the opposite by design: each one is written to your organization's audit trail so you can evidence checks later.
Why am I seeing a rate-limit message?
Free searches are limited per IP address each minute to keep the tool responsive for everyone. Wait the few seconds shown and try again. If you are checking more than a handful of names, the API is the right tool — the free tier includes 10,000 screening requests per month.
What does a “Delisted” result mean?
The entry was removed from its source list — OFAC delists parties when designations are lifted. Delisted entries rank below active ones here and are excluded from API screening verdicts, but they are worth reviewing: a counterparty's delisting history can still be relevant to your risk assessment. The delisted entities page tracks recent removals.
Which lists does this search besides the SDN list?
Every list CompliAPI screens against: the OFAC SDN and Consolidated (non-SDN) lists, plus international sanctions registers (EU, UK FCDO, French Trésor, Japan MOF, Israel NBCTF) and crime-intelligence sources such as FBI-attributed Lazarus Group addresses and ransomware payment addresses. Every result names the list it came from, so an SDN hit is always distinguishable from the others.
