OFAC is a U.S. Treasury office that maintains lists of people and organizations the government has sanctioned, and banks must check customer names and transactions against those lists before moving money

OFAC stands for the Office of Foreign Assets Control. It is part of the U.S. Department of the Treasury. OFAC publishes lists of individuals, companies, and countries that the U.S. government has placed under sanctions — meaning Americans and American banks are prohibited from doing business with them or moving money to them.

When you send a wire transfer, open a bank account, or receive a large deposit, your bank runs your name against OFAC's lists. If your name matches or closely resembles a name on the list, the bank will freeze the transaction or account until it can confirm you are not the sanctioned person. This is not a judgment about you — it is a legal requirement the bank must follow.

The lists change regularly as the U.S. government adds and removes sanctioned entities. OFAC publishes updates multiple times per week. Banks use automated screening software to check names in real time, which is why a transaction can be delayed or blocked within minutes of you initiating it.

Key Takeaways

  • OFAC is a Treasury office that publishes lists of sanctioned people, companies, and countries that U.S. banks cannot do business with.

Why banks screen against OFAC lists

U.S. law requires every bank to screen customers and transactions. Failure to do so can result in massive fines, criminal charges against bank officers, and loss of the bank's license to operate. The penalties are severe enough that banks treat OFAC screening as a core function, not an afterthought.

The screening serves two purposes. First, it prevents money from flowing to countries and individuals under U.S. sanctions — currently including Iran, North Korea, Syria, Russia (with exceptions), and Cuba, among others. Second, it blocks transactions involving people designated as terrorists, drug traffickers, or money launderers. The lists are maintained by OFAC based on intelligence from the FBI, CIA, State Department, and other agencies.

Banks screen at multiple points: when you open an account, when you send a wire transfer, when you receive a large deposit, and sometimes during routine account reviews. The screening is automated, which means it happens in seconds and does not require a human to review your transaction first.

What happens when your name matches an OFAC list

If your name matches or closely resembles a name on an OFAC list, the bank's system will flag the transaction or account. The bank then has a legal obligation to investigate before proceeding. This investigation typically takes a few days to a few weeks, depending on how clear the mismatch is.

During the investigation, the bank will ask you for identifying information: your date of birth, address, passport number, or other documents that prove you are not the sanctioned person. If your information clearly does not match the sanctioned individual — for example, you are a U.S. citizen and the sanctioned person is a foreign national — the bank will clear the hold and process your transaction.

If the match is ambiguous, the bank may file a report with OFAC itself asking for clarification. OFAC can issue a license that allows the bank to proceed with the transaction, or it can confirm that you are indeed the sanctioned person, in which case the transaction will be permanently blocked. This process can take weeks.

Common reasons for false matches

OFAC lists contain thousands of names, and many are common names shared by millions of people worldwide. A person named "Mohammad Ahmed" or "Maria Garcia" has a higher statistical chance of matching a name on the list straightforward because those names are widespread. The bank's screening software is designed to flag close matches, not exact matches, because sanctioned individuals sometimes use aliases or slightly altered names.

Variations in spelling, transliteration from other languages, and name order differences also cause false matches. A name spelled "Muhammed" in one system and "Mohammad" in another will often trigger a flag. Similarly, some cultures place family names first, which can cause confusion when the name is entered into a Western database.

If you are flagged, the bank will ask for documents that establish your identity and citizenship. Having a passport, driver's license, or state ID ready will speed up the process. The bank is not accusing you of anything — it is following the law.

How to resolve an OFAC hold on your account or transaction

Contact your bank's compliance or customer service department when ready if your transaction is blocked or your account is frozen due to OFAC screening. Do not wait — the longer the hold sits, the longer your money is unavailable.

Provide the bank with government-issued identification, your date of birth, and your address. If you have a passport, that is the fastest document to provide because it contains your citizenship status. The bank will compare this information to the sanctioned person's profile on the OFAC list.

If the mismatch is clear, the bank should clear the hold within a few business days. If the match is closer or the bank is uncertain, it may take longer. Some banks will process your transaction while the investigation is ongoing if the mismatch is obvious, but others will hold the funds until the investigation is complete. Ask your bank which approach it is taking.

If you believe the hold is in error and the bank is not moving quickly, you can file a complaint with your bank's regulatory agency — usually the Federal Reserve, the Comptroller of the Currency, or the Federal Deposit Insurance Corporation, depending on the bank's charter. You can also contact OFAC directly to request a license or clarification, though this is a slower process.

OFAC screening and wire transfers

Wire transfers trigger OFAC screening at both the sending and receiving bank. When you initiate a wire, your bank screens your name. When the wire arrives at the receiving bank, that bank screens the recipient's name. If either bank flags a match, the wire can be delayed or rejected.

International wire transfers are screened more carefully because they cross borders and may involve countries under sanctions. A wire to Iran, North Korea, or Syria will be rejected outright. A wire to a country that is partially sanctioned — such as Russia — will be screened more thoroughly to may support the recipient is not a sanctioned entity.

If your wire is rejected due to OFAC screening, the sending bank will notify you and return the funds to your account. The process can take several days. You will need to resolve the issue with the receiving bank or provide additional information to your sending bank before trying again.

OFAC lists and what they contain

OFAC maintains several lists, each serving a different purpose. The Specially Designated Nationals List (SDN) is the primary list and contains individuals and entities the U.S. government has designated as terrorists, drug traffickers, or threats to national security. The Consolidated Non-SDN List contains entities that are blocked but do not meet the SDN criteria. There are also sector-specific lists for countries like Iran and Russia.

Each entry on an OFAC list includes the person's or entity's name, aliases, date of birth (if known), nationality, and the reason for designation. Banks use this information to determine whether a customer or transaction matches the list. The lists are public and available on OFAC's website, though the full details of why someone was designated may be classified.

OFAC updates its lists multiple times per week as new sanctions are imposed or existing ones are lifted. Banks receive these updates automatically through their screening software, so the screening is always current.

Frequently Asked Questions

Can I be denied a bank account because of OFAC screening?

Yes, if your name matches a sanctioned person and you cannot prove otherwise, the bank can refuse to open an account for you. However, most banks will work with you to resolve the mismatch if your identifying documents clearly show you are a different person. If one bank denies you, another may not flag the same match, depending on their screening software.

How long does an OFAC investigation take?

A clear mismatch can be resolved in one to three business days. An ambiguous match may take one to two weeks. If the bank files a report with OFAC requesting a license or clarification, the process can take several weeks or longer. Contact your bank for a timeline specific to your situation.

Will being flagged by OFAC affect my credit score?

No. OFAC screening does not report to credit bureaus and does not affect your credit score. It is a compliance check, not a credit check. Once the hold is resolved, there is no lasting record on your credit report.

What if I am actually on an OFAC list?

If you are designated on an OFAC list, you cannot conduct business with U.S. banks or receive money from U.S. sources. You can petition OFAC to remove you from the list, but this is a lengthy legal process. If you believe you were designated in error, contact OFAC directly to request a review.

Do international banks have to screen against OFAC lists?

No. OFAC is a U.S. government office, so only U.S. banks and U.S. branches of foreign banks are required to screen. However, foreign banks that want to do business with U.S. banks often screen against OFAC lists voluntarily to avoid complications.
