How to check crypto companies and wallet addresses in OFAC records

OFAC tool checks names and exact crypto addresses

The U.S. Treasury's Office of Foreign Assets Control, or OFAC, runs U.S. sanctions that can ban dealings with listed people and companies and freeze their assets. Its free Sanctions List Search lets the public check company names and crypto addresses.

A wallet address is a string of characters used to identify a crypto wallet. A search is not permission to transact. Finding a possible match is different from establishing what restrictions apply.

Key points for searching

• The tool covers the SDN List and other OFAC consolidated lists. Different lists can carry different restrictions.
• For a company, use the Name field and check legal names, trading names and aliases.
• For a wallet, paste the full address into the ID # / Digital Currency Address field. It returns only exact matches.
• An unlisted wallet or company may still be subject to blocking rules.

Why the list and program columns matter

The returned List and Program(s) columns show which list and programme apply. Readers should check those fields, not only the name.

For a company, open a possible result and compare the full entry with identifying details such as registration numbers and location. OFAC says a similar name, or even a shared street address, does not alone prove identity.

The name search can return approximate matches. The Minimum Name Score measures name similarity, not the chance a company is sanctioned. A score of 100 returns exact name matches. Lowering it broadens results, and OFAC does not recommend one threshold for every search.

For a wallet address, compare the returned address character for character. Also check the currency label in the record. OFAC structures the identifier as Digital Currency Address, a currency symbol and the specific address.

November 6 notice shows why details matter

OFAC's November 6, 2026 notice added eight Canadian money-services businesses to the SDN List. Treasury said it designated them under Executive Order 13902 for operating in Iran's digital asset sector.

One entry named Diverse Trade Inc. It listed aliases including Million Exchange, Million Money Exchange and Millionex. It also gave Canadian registration identifiers, locations, a website and a digital-currency address labelled TRX.

The same notice listed Cryptoyal as an alias for both B Galaxy Inc. and CCC Inc. Their company registration numbers differed. This shows why a brand name alone is not enough to identify a legal entity.

The entries carried the programme code IRAN-EO13902. Treasury's release explained the designation basis and blocking consequences.

What a match or no match does not settle

An apparent match needs investigation. Organisations are directed to compare all available identifying details and follow their sanctions-compliance procedures. For a valid match, the applicable rules decide whether property must be blocked, a transaction rejected, or an authorisation or exemption applies.

An unlisted address is not necessarily outside sanctions. OFAC warns that its published crypto addresses are unlikely to be exhaustive. The restriction concerns the blocked person's property interests, not only listed addresses.

An unlisted company can also be blocked. Under OFAC's 50 Percent Rule, an entity owned 50% or more, directly or indirectly and in aggregate, by blocked persons is itself blocked even without its own SDN entry.

Use current records for current checks. OFAC says the search tool excludes removed names and shows updated entries rather than historical versions. The tool states that using it does not replace due diligence or limit civil or criminal liability.
