In Europe and the SEPA zone, bank accounts are identified using an IBAN (International Bank Account Number). There are several methods to verify an IBAN holder and protect against payment fraud : from simple document checks to dedicated bank-level solutions. They do not all offer the same level of reliability or the same conditions of use. This verification is often essential before making a payment, for example to a supplier, an employee or a customer.
Can you identify the owner of an IBAN?
When trying to secure a payment, a common question is whether it is possible to identify the owner of a bank account using an IBAN alone.
In practice, it is important to distinguish between two very different actions:
- identifying the owner of an IBAN
- verifying that an IBAN matches a known person or company
Obtaining the name of a bank account holder from an IBAN alone is generally not possible. In Europe and most jurisdictions, banking data is protected by privacy regulations and banking secrecy laws. There is no public directory that allows you to identify the owner of a bank account from an IBAN.
However, it is possible to verify whether an IBAN corresponds to an identity you already have for example, a vendor, a customer, or an employee.
This process consists of confirming that a “name + IBAN” pair is consistent, without revealing any additional personal or banking information.
Before reviewing the available methods, it is also important to distinguish between:
- IBAN format validation
- IBAN owner verification
Format validation consists of checking whether an IBAN is structurally valid (length, checksum, country code). This type of check is widely available and easy to implement.
However, it does not provide any information about the identity of the account holder and does not protect against fraud. A structurally valid IBAN can still belong to the wrong beneficiary.
IBAN format validation is therefore a useful first step, but it is not sufficient to secure a payment or confirm ownership.
What are the different methods to verify an IBAN holder?
There are several ways to verify whether an IBAN matches the expected individual or company. These methods differ in reliability, scalability, and ease of implementation.
Document-based verification (bank details / proof documents)
The most common method is to request a proof documents showing the bank details and to check that the name displayed on the document matches the expected beneficiary.
This approach is simple and requires no specific tools, but it is inherently unreliable.
Documents can be easily altered using image editing software or AI tools.
To strengthen this process, companies often request additional documents such as:
- Company registration documents
- Identity documents
While this can improve consistency, it does not prove that the bank account actually belongs to the person or company.
A fraudster can provide legitimate company documents alongside a falsified IBAN document. The information appears coherent, but the account belongs to the fraudster.
Some companies also attempt to confirm details by contacting the beneficiary directly (email or phone), but this approach is time-consuming and still not fully reliable.
Limitations:
- Documents can be falsified or manipulated and no direct link is verified between identity and bank account
- Manual and time-consuming
- Not scalable for large volumes
- High risk of human error and fraud
Verification via your bank (Verification of Payee - VoP)
Since October 2025, European banks are required to provide beneficiary verification at the time of payment under the Verification of Payee (VoP) regulation.
This mechanism compares the name entered with the one associated with the IBAN and returns a match result.
VoP improves payment security by adding a verification step before executing a transfer.
However, it has important limitations, especially for business use cases. This method acts as a safety net for individual payments, but is not suitable for systematic verification processes.
Limitations:
- Only available at the moment of payment
- Cannot be used for upstream controls (vendor onboarding, audits, etc.)
- Depends on bank interfaces
- No API integration for automation
Beyond manual methods, dedicated solutions allow companies to automate IBAN holder verification at scale. These solutions rely on different technical approaches, which offer varying levels of reliability.
Solutions based on data aggregation and shared databases
Some solutions rely on databases built from aggregated information such as payment history, user-contributed data, and third-party sources.
These solutions assess whether a “Name + IBAN” combination appears consistent based on available data.
These systems typically return a confidence score, with a higher or lower level of certainty depending on the data available and the sources used. In general, they provide a “favorable” or “unfavorable” opinion rather than a final and definitive confirmation.
While useful for detecting anomalies, they do not provide a real confirmation from the bank.
Limitations:
- Coverage depends on database size and freshness
- Data can be partially declarative and the result is obtained from algorithms whose decision rules are subjective. Fraudulent accounts can thus receive a “favorable” result.
- Risk of false positives or false negative
- These solutions are often expensive because they rely on complex algorithms and infrastructure.
Solutions based on Open Banking
These solutions rely on open banking mechanisms to validate account information. They require the explicit consent of the account holder who must connect to their bank space to authorize access to their personal data as part of the verification.
The user connects to their bank account and authorizes access to their data, allowing verification directly from the source.
This method makes it possible to obtain reliable confirmation, but it remains restrictive to deploy in many contexts, especially when it is necessary to carry out checks quickly, frequently or without interaction with the beneficiary.
Limitations:
- Requires the explicit consent of the owner with manual action on his part, and therefore depends on his availability at the time of verification
- Difficult to integrate into automated paths
- Not suitable for mass checks
- May generate friction in user journeys (registration, subscription, etc.)
Solutions based on direct bank verification
Some solutions verify IBAN ownership by directly querying the bank holding the account.
A “Name + IBAN” pair is sent to the bank, which compares it with its internal records and returns a match result (match / no match / partial match).
This approach relies on national and international interbank networks, making it possible to confirm the correspondence between the IBAN and the beneficiary based on data held by banking institutions.
It does not require user interaction and does not depend on declarative data.
These checks can be carried out before a transfer, on an ad hoc basis or on large volumes, as required.
The main limitation of this type of solution is geographical coverage, which depends on the banking networks available in each country. However, most European countries now have banking infrastructures that make direct bank verification possible.
Summary
The IBAN verification methods differ greatly in terms of reliability, ease of implementation and the ability to integrate into your internal processes.
Manual or document-based approaches may be sufficient for occasional checks, but quickly become inadequate for larger volumes or higher-risk situations.
The choice will therefore depend on the level of risk and the uses.
Comparison of methods to verify the holder of an IBAN
As we have just seen, there is not a single method for verifying an IBAN, but several approaches with very different levels of reliability and scalability. The table below compares their main characteristics.
As this comparison shows, not all methods meet the same needs.
Manual or ad hoc approaches may be sufficient in some cases, but they quickly reach their limits as soon as volumes increase or financial challenges are high.
In these cases, solutions that allow reliable and systematic confirmation become necessary.
💡 Key takeway: only verification by direct bank query allows reliable confirmation without depending on third party data or on the consent of the beneficiary and can easily be integrated into internal processes
Use cases: when should you verify an IBAN?
Verifying an IBAN holder is critical in many business scenarios, from fraud prevention to regulatory compliance and operational efficiency.
Depending on the context, the level of risk varies, and so does the required level of verification. In some cases, basic checks may be enough. In others, reliable and automated verification becomes essential.
Vendor onboarding
This is one of the highest-risk moments for finance teams. So-called “vendor fraud” is increasingly common: a fraudster impersonates a legitimate supplier and provides fraudulent bank details to divert payments.
Verifying IBAN ownership when creating or updating vendor records ensures that payments are sent to the correct company, and protects all future transactions.
Salary payments
Incorrect or fraudulent bank details can lead to misdirected salary payments. Businesses with a large number of employees and frequent staff turnover are particularly at risk.
Verifying IBANs ensures that salaries are sent to the correct employee accounts, avoiding administrative disputes and financial losses.
Insurance payouts
Fraudulent IBANs can be used to divert insurance payments.
Verification ensures that funds are sent to the legitimate policyholder.
Credit and lending
In the subscription process for loans, the verification of the IBAN holder occurs at several key stages.
It is first and foremost part of a global customer knowledge approach (KYC, Know Your Customer), by making it possible to verify the consistency between the declared identity and the bank details, in addition to the other checks carried out before a loan is granted.
It also makes it possible to secure the release of funds by ensuring that the transfer is made to the right beneficiary, as well as the establishment of direct debits for monthly payments.
In some cases, it also contributes to meeting regulatory requirements.
These uses require methods that are reliable, fast and can be integrated into digital journeys, without creating friction for the user.
Leasing and rental platforms
When a valuable vehicle or equipment is made available, the risk is financial but also material. A falsified RIB often accompanies broader identity theft.
Checking the bank account holder makes it possible to ensure the legitimacy of the tenant and to prevent the theft or embezzlement of goods, while ensuring that the monthly payments will be taken from the correct account.
Customer onboarding
In addition to taking out credit, some online subscription processes require KYC checks (Know Your Customer) thorough. Sometimes it is even a regulatory obligation. The IBAN can then be used as a control element in its own right.
The challenge is to confirm the correspondence between a customer and their bank details, while limiting friction in the user journey.
Mass verification and existing basic audit
In some cases, it may be necessary to check a large number of IBANs, for example during a migration, an internal audit or a basic cleaning of suppliers or customers.
These situations require methods that can handle large volumes in a reliable and automated manner.
This list is of course not exhaustive and there are a multitude of other cases in which it is necessary to verify the holder of an IBAN.
Depending on the context, some methods quickly reach their limits, especially when it comes to automating controls or dealing with large volumes.
Approaches that allow for reliable, rapid verification and without beneficiary intervention then become essential.
How does the verification of the holder of an IBAN by bank query work?
Some solutions allow you to verify the holder of an IBAN by directly asking the bank that holds the account.
Concretely, a “name + IBAN” combination is sent to the bank, which compares this information with the data it holds in its own database and returns a match result: correspondence, absence of correspondence or partial correspondence.
This verification is carried out without disclosing sensitive information and without requiring the intervention of the account holder.
It can be carried out in a few seconds, on an ad hoc basis via an interface, or integrated into business tools (ERP, accounting software, KYC platforms, HR tools) in order to automate large-scale controls.
This type of approach thus makes it possible to secure payments, to make data reliable and to reduce the risks of fraud, while easily integrating into existing processes.

Conclusion
Checking the IBAN holder is an essential step to secure payments and avoid fraud.
As we have seen, several methods exist, but they do not all offer the same level of reliability or the same possibilities of use.
While some approaches may be sufficient for spot checks, they quickly reach their limits as soon as volumes increase or the issues become critical.
In these cases, solutions that allow reliable and systematic verification of the beneficiary become necessary.
