OFAC is the Office of Foreign Assets Control, the US Treasury unit that administers American sanctions programmes and publishes the SDN List. Digital currency addresses can appear on that list as identifiers attached to a designated person or entity, which is why sanctions are the first thing a desk resolves on a counterparty address. A sanctions match is not a risk you weigh against commercial upside; it is a legal fact about who is on the other side of the transfer.
OFAC administers US sanctions programmes and maintains the Specially Designated Nationals and Blocked Persons List. Its FAQ 559 defines the terms it uses for this asset class: "digital currency", "digital currency wallet", "digital currency address" and "virtual currency". The address is an identifier; the wallet holds addresses and the keys that control them. That distinction is why a designation can attach to something as small as a single string of characters.
Because a sanctions result is the one outcome with no room for judgement. OFAC's virtual-currency FAQ topic page sets out that digital currency addresses can appear as identifiers on the SDN List and that US persons must block property and interests in property of designated persons. For an exchanger, an OTC desk or a P2P trader, that turns a routine settlement into a reportable event: the transfer does not happen, the funds are not returned "to be safe", and the decision has to be documented.
Every other risk category on a check answers "how likely is this to become a problem". Sanctions answers "is this already a problem". You want that question resolved before you quote a price, not after you have accepted a deposit. Paste the counterparty address into the Telegram bot before the deal — three free checks a day, verdict in seconds.

The lookup is public, so a one-off check on a single address is something anyone can do by hand. What the manual route does not give you is the rest of the picture: whether the address never appeared on a list itself but received its balance from one that did, and whether the counterparty is one hop or five from a designated cluster.
A sanctions connection is named as its own category in the result, in plain words. You see the verdict — CLEAN, LOW, MEDIUM, HIGH or CRITICAL — with a recommendation next to it (Proceed, Caution, Review or Reject), and the decision drivers written out so you know which finding produced the verdict rather than having to infer it. A designation on the address itself and a designation somewhere in its funding history read differently in the result, because they are different obligations for you.
Desks run the same check in the workspace, where a sanctions category becomes a filter on the case queue and every result exports as a signed report you can forward to a bank or an auditor. Plans and limits are on the pricing page; the Telegram bot stays free for three checks a day if you only need the answer.
Yes. OFAC's virtual-currency FAQ topic page states that digital currency addresses can appear as identifiers on the SDN List, and that US persons must block property and interests in property of designated persons. The asset class does not create an exemption.
It sets out what OFAC means by "digital currency", "digital currency wallet", "digital currency address" and "virtual currency" for sanctions purposes. In short: an address is an identifier, and a wallet is what holds addresses and the keys to them.
Yes, through OFAC's Sanctions List Search, and the full list is downloadable from the Sanctions List Service. Doing it by hand answers whether that exact string is listed; it does not tell you whether the balance arrived from an address that is.

Stop the transfer, keep the record of what you found and when, and follow your own reporting obligations in your jurisdiction. Do not send the funds onward and do not return them without advice — both are decisions with legal consequences.
