A payments firm in Singapore processes a transfer. The receiving bank's screening system returns a positive match against the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). The match is not the account holder. It is someone with a similar name, a shared date of birth format, or an address in the same city. The transaction is frozen. The client's account is suspended. Within hours, the business is effectively locked out of the US dollar system – not because it is sanctioned, but because a machine said the names looked alike.
Mistaken-identity removals under OFAC are formal requests to the US Treasury's Office of Foreign Assets Control to remove a non-designated person or entity from a blocked or frozen position caused by a false match against the SDN List or a related OFAC list. The governing authority is OFAC itself, acting under the powers delegated to it under IEEPA and related instruments. Resolution requires a structured evidentiary submission, not a phone call – and the window to act effectively is shorter than most businesses expect.
This page explains how the mistaken-identity removal process works under OFAC, where it diverges from the comparable procedures under OFSI and the EU, and how Calder & Vance assists clients through every stage of the matter.
What is a mistaken-identity match and why does it happen?
A mistaken-identity match occurs when an automated or manual screening system flags a person, company, or account as a potential match against a listed entry on the SDN List, but the flagged party is not the designated person or entity. The error is a product of the screening process, not of the underlying sanctions list itself.
Screening systems operate on algorithms that compare names, dates of birth, nationalities, addresses, and other identifiers against list entries. They are designed to cast a wide net. A match score above a defined threshold generates an alert. That alert can trigger an automatic block on a transaction, a freeze on an account, or a refusal of onboarding – all before any human analyst has confirmed the match.
The common causes are well documented in our practice. Transliteration differences produce multiple Latin-script renderings of the same Arabic, Cyrillic, or Chinese name. Shared surnames within ethnic communities mean that a listed person's family name is common across entire populations. Date-of-birth formats create false positives where day and month fields are transposed. Address data may overlap because a listed person once operated from a building now occupied by an entirely unrelated business.
The consequence for the non-designated party is immediate and severe. Correspondent banks suspend payment chains. Trade finance facilities are withdrawn pending investigation. Import and export licences are placed on hold. Onboarding decisions are refused. These impacts accumulate quickly, and they compound if the mistaken match is propagated through data-sharing between financial institutions. Speed matters more in a mistaken-identity matter than in almost any other type of sanctions work.
What authority governs the removal process, and what does OFAC actually do?
OFAC administers the removal process under IEEPA, the Trading with the Enemy Act, and the specific programme regulations that govern each sanctions list. It is a US government agency within the Department of the Treasury. Its decisions on mistaken-identity claims are administrative determinations: OFAC reviews the evidence submitted, compares it against the list entry, and either confirms that the submitting party is not the designated person or entity, or declines to issue that confirmation.
A confirmed non-match does not mean OFAC amends the list. The SDN entry remains unchanged, because it relates to the designated person, not to the party raising the mistaken-identity claim. What OFAC provides is a written statement that it has reviewed the matter and does not consider the submitting party to be the listed person. That statement – sometimes referred to as a delisting letter in informal usage, though the technical term in this context is a confirmed non-match determination – is then used to unblock accounts, restart transactions, and reset correspondent banking relationships.
As of early 2026, OFAC also maintains a specific pathway for individuals and entities that believe they have been blocked solely by reason of a mistaken identity. The process is distinct from the formal administrative petition filed by a listed person who disputes their own designation. The two routes have different evidentiary requirements, different timelines, and different legal consequences. Conflating them is one of the more common errors we see in submissions prepared without specialist assistance.
The position above covers the standard case. Your facts – the nature of the match, the regime triggering the block, the jurisdictions of the financial institutions involved, and the urgency of the underlying transaction – change the analysis significantly.

How does the mistaken-identity removal procedure work in practice?
The mistaken-identity removal procedure requires the affected party to submit a structured package of evidence to OFAC demonstrating, on the material before the agency, that the submitting party is not the person or entity named in the relevant SDN entry. The submission must address each point of apparent similarity and explain why, correctly analysed, the match does not hold.
The process unfolds in recognisable stages. First, the affected party must obtain a precise copy of the SDN entry that generated the match, including all associated identifiers. This sounds straightforward. In practice, banks often decline to share the precise basis of a block, citing their own compliance obligations. Identifying the exact entry – and therefore the exact identifiers that require rebuttal – is frequently the first substantive task for counsel.
Second, the affected party assembles the evidential case. The core materials typically include: government-issued identity documents establishing the correct name, date of birth, and nationality of the submitting party; corporate registration documents where the flagged entity is a legal person; address history and registered-office records; and any other materials that directly contradict the identifiers in the SDN entry. Supporting declarations may be required where documentary evidence alone is ambiguous.
Third, the submission is filed with OFAC through the prescribed channel. OFAC acknowledges receipt. It then reviews the package, which may involve queries back to the submitting party for additional materials. Timelines vary. They depend on OFAC's case volume, the complexity of the identifiers at issue, and whether the submitting party has provided a complete package from the outset. An incomplete submission almost always extends the process and may invite a refusal without prejudice to refiling.
Fourth, OFAC issues its determination. A positive determination confirms the non-match. That document is then used in communications with the blocking institution to obtain release of the frozen assets or resumption of the blocked transaction.
Throughout, the submitting party must manage parallel communications with the financial institution that imposed the block. The institution has its own compliance obligations and will not simply release a hold because the customer asserts a mistaken identity. A formal OFAC determination, combined with well-drafted correspondence to the institution's compliance team, is the standard route to resolution.
How does the OFAC mistaken-identity route compare to OFSI and EU procedures?
The OFAC mistaken-identity removal procedure is mechanically different from the comparable routes under the UK's OFSI and the EU's Council regulations, and those differences matter for cross-border businesses whose accounts or transactions are blocked in multiple jurisdictions simultaneously.
Under OFSI, a person who believes they have been incorrectly identified as a designated person may apply to OFSI for a licence or for a formal clarification. OFSI's approach to ownership and control (the UK and EU test for whether a non-listed entity is caught through a listed person) also produces a distinct category of mistaken-identity-adjacent situation: a business may find itself treated as owned or controlled by a listed person based on a misapplication of the control test, rather than a direct name match. That route – contesting the application of the ownership-and-control analysis – requires a different legal argument and a different evidentiary presentation than a pure identity-mismatch case.
Under EU law, a person or entity that is not listed but has been incorrectly treated as though it were may contest that treatment in the courts of the relevant member state, or may approach the European External Action Service for clarification. Where the block is imposed by an EU-regulated institution, the applicable national competent authority – the equivalent of OFSI in each member state – is the relevant point of contact.
The practical implication for a multinational business is that a mistaken-identity event originating in a US correspondent bank may propagate to EU and UK institutions through data-sharing. Each institution will require resolution under its own regulatory requirements. OFAC's determination resolves the US position. It does not automatically resolve the OFSI or EU position. Coordinating submissions across regimes simultaneously – rather than sequentially – reduces the total period of disruption.
We regularly advise clients on coordinated multi-regime mistaken-identity submissions. The evidence base is largely shared, but the framing, the recipient authority, and the legal basis for each submission differ. A submission drafted only for OFAC will frequently need significant reworking before it is appropriate for submission to OFSI or a European competent authority.
If a transaction has already been frozen, or a financial institution has declined to onboard your business, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com for a confidential assessment.
What are the main risk flags in a mistaken-identity matter?
The principal risk in a mistaken-identity matter is delay. Every day that an affected party waits before filing a structured submission is a day in which the block compounds. Correspondent banks report the position in their own internal systems. Trade credit facilities are withdrawn. Counterparties treat the situation as confirmation of a problem. By the time a formal submission is filed, the affected party may be managing reputational damage as well as the underlying block.
A second risk is an incomplete or unstructured submission. OFAC reviews submissions against the specific identifiers in the SDN entry. A submission that addresses the name similarity but not the date-of-birth overlap, or that addresses the individual but not the company with which they are associated, will not resolve the matter. Worse, a poorly prepared submission can prejudice the subsequent case by creating a record of inconsistencies that a later, corrected submission must explain.
A third risk is simultaneous action by the blocking financial institution. Some institutions, on receiving a mistaken-identity complaint from a client, file their own query with OFAC. That parallel filing may or may not be consistent with the affected party's own submission. Where the institution frames the query differently from the affected party's submission, OFAC may receive conflicting accounts of the same facts.
A fourth risk is the propagation problem described above. A mistaken-identity match in one institution will often be replicated across others within days, because institutions share customer data and alerts through industry networks. Acting on the primary block before it propagates is meaningfully faster than unpicking it from multiple institutions after the fact.
Finally, there is a structural risk specific to entities: a business that shares a name, registration number, or address with an SDN-listed company may face a recurring pattern of mistaken-identity matches even after a first OFAC determination has been obtained. In that situation, a one-time submission is not enough. The affected business needs a durable solution – which may include a request for an OFAC-issued "cleared" reference, a legal name or registration change, or standing correspondence with its key financial institutions that can be produced at each recurrence.
A common misconception: "once cleared, we are protected going forward"
In our experience, the most persistent misconception in mistaken-identity matters is that a single OFAC determination provides permanent protection. It does not. The determination confirms that, at the time of the submission, OFAC did not consider the submitting party to be the designated person. It does not bind future screening systems, future financial institutions, or future list updates that may add new entries with similar identifiers.
If the designated person's SDN entry is updated – for example, with a new alias or address that more closely resembles the affected party's details – the risk of a renewed false match increases. If the affected party changes its registered address, acquires a new trading name, or enters a new jurisdiction, those changes may themselves generate new match points against existing or future SDN entries.
The practical answer is not to avoid these activities. It is to treat the mistaken-identity risk as an ongoing compliance matter, not a one-time event. That means maintaining a record of the OFAC determination and the supporting evidence in an accessible form, briefing key financial institutions proactively when material changes occur, and running periodic checks against the SDN List on the affected party's own identifiers. We advise clients on building exactly this kind of standing protocol as part of a broader sanctions compliance programme.
How Calder & Vance assists with mistaken-identity removals under OFAC
Calder & Vance acts for businesses, financial institutions, and individuals at every stage of the mistaken-identity removal process under OFAC. Our work in this area draws on J. M. Aldridge's focused practice in OFAC licensing and sanctions administration, combined with the firm's cross-regime coverage for matters that involve parallel OFSI or EU positions.
In a recent matter, a financial services business in Southeast Asia found that its accounts at a major US correspondent bank had been suspended following an automated screening alert. The SDN entry in question related to an entity with a near-identical name and a partially overlapping registration address in the same city. We assessed the entry, identified the specific identifiers driving the match, and prepared a structured evidentiary submission to OFAC addressing each point of apparent similarity. We managed OFAC's queries during the review period and coordinated parallel correspondence with the correspondent bank's compliance team. The accounts were restored, and the client received a formal confirmation of non-match from OFAC.
For a new instruction, our process is as follows. We assess the SDN entry and the basis of the block, advise on the strength of the non-match argument, and agree a fixed-fee scope for the submission work. We then prepare and file the submission, manage the OFAC review, and handle the parallel financial-institution correspondence. Where the matter involves an OFSI or EU dimension, we coordinate the cross-regime filings from the same evidence base. Where the mistaken-identity risk is structural and likely to recur, we design a standing protocol for the affected party's compliance team.
The full range of tasks we perform in a mistaken-identity matter includes: identifying the precise SDN entry and its operative identifiers; assembling and quality-checking the evidence package; drafting the OFAC submission; managing queries and supplemental filings; coordinating with blocking financial institutions; and, where needed, preparing OFSI and EU parallel submissions.
