Interpol Blue Notice
Interpol Blue Notice is used in ongoing investigations and helps law enforcement agencies exchange information among Interpol member countries. The article examines the conditions for its issuance, the categories of individuals who may become its subjects, and possible consequences, including the potential for an international alert. It also describes the differences between the Blue Notice and other Interpol notices, as well as ways to submit a removal request. Particular attention is paid to the procedure for removing the notice and legal assistance in such cases.

What is an INTERPOL Blue Notice?
An Interpol Blue Notice is one of the types of notifications used for international information exchange between law enforcement agencies. Other notices include the green notice, red notice, and yellow notices.
But can a Blue Notice lead to arrest or detention?
Well, a blue notice doesn’t imply detention or formal charges like an international arrest warrant but serves an auxiliary function – allowing the acquisition of critical crime-related information to obtain information about a person. That includes their whereabouts, or related facts, which can help seek persons wanted, particularly in collaboration with the international criminal court. Such a notification may be issued to locate missing persons when an individual cannot be identified, their data is incomplete, or if they have disappeared under unknown circumstances and their location is important for the investigation.
An official request for the publication of a Blue Notice is submitted by the Interpol national central bureau of a member country. It contains available data about the person, a photograph (if available), and the grounds for the request. After verifying the information and confirming compliance with the organization’s rules, the notice becomes accessible to all Interpol member states. This enables investigative authorities in other interpol member countries to provide additional information that may contribute to the ongoing investigation or assist in locating the person, including critical crime-related information utilizing national and international databases.
Interpol Blue Notice request is widely used in cases requiring international cooperation for public safety. It can concern not only suspects in crimes but also witnesses who may possess key information for the investigation. Additionally, such a request can be used to search for missing persons if there is a suspicion that their disappearance is connected to committing crimes or may have an international aspect.
Who is the Subject of Blue Notice?
The Blue Notice can be issued regarding various individuals whose data or whereabouts are of interest to law enforcement agencies. Most often, the subjects of such a notice are suspects whose location is unknown. These may be people on the run, individuals whose identities have not been officially established, or persons evading investigative actions in their own country, impacting the person’s identity. Interpol uses the Blue Notice when it is necessary to seek information about the movements of such individuals or establish their contacts in other member countries.
Another category consists of witnesses who may possess important information capable of influencing the course of the investigation. If a person has disappeared or is out of contact, law enforcement agencies can request the publication of a Blue Notice to determine their whereabouts. In such cases, the notice helps member countries quickly exchange data, obtaining new facts for further investigation, including information on unidentified bodies and efforts to locate missing persons, showcasing international efforts in the pursuit of justice.

Blue Notice is also used to search for missing persons if there are grounds to believe that their disappearance may be connected with serious crimes, prompting immediate action. This is particularly relevant in cases of human trafficking, abductions, or criminal schemes where a person may be forcibly moved across borders, posing a serious and imminent threat. For example, in one of the European countries, the publication of a Blue Notice was initiated to establish the whereabouts of a young man who was allegedly a victim of illegal border crossing by an organised group.
In certain cases, Interpol uses a Blue Notice to gather information about individuals involved in transnational crime. These could be persons of interest in cases of fraud, corruption, financial manipulations, or money laundering. Such crimes often affect multiple jurisdictions, making international data exchange a key factor in combating criminal activities . A Blue Notice allows connections between participants in criminal schemes to be identified, similar to how a Green Notice can help in tracking individuals involved in less severe offenses, aiding in uncovering their activities on a global scale.
What is the Process for Issuing an Interpol Blue Notice?
The process of issuing a Blue Notice begins with a request submitted by the law enforcement agencies of one of the member states through the National Central Bureau (NCB). It specifies the reasons for publication, available information about the individual, their possible location, and connections that may be of interest to the investigation for Interpol member states. It is important that the provided information complies with the rules of Interpol notices, including diffusion notice guidelines, and does not have a political, military, racial, or religious orientation; otherwise, the request will be rejected.
After applying, the General Secretariat of Interpol verifies the information, assessing its compliance with international standards. If the application is approved, a Blue Notice is published in Interpol’s global system, and law enforcement agencies of all other member states gain access to it. The notice is used to locate the wanted person and gather data on their movements and possible accomplices, which can sometimes lead to an arrest warrant in conjunction with a Red Notice.
Blue notices can be issued during investigations of fraud, corruption, tax evasion, financial schemes, and money laundering, as well as crimes related to drugs, human trafficking, abductions, crimes against minors, organized crime, and terrorism. If a person has fled to another country or their whereabouts are unknown, blue notices help coordinate the efforts of law enforcement agencies and facilitate the prompt exchange of important information, including international requests related to ongoing criminal activities.
One of the features of Blue Notices is the ability to update data. If new facts emerge, Interpol can make changes to the notice, specifying travel routes or contacts of the person being sought. This speeds up the process of locating suspects, witnesses, or missing persons and prevents evasion of investigative actions in the realm of international law enforcement.
Differences Between an Interpol Red Notice and a Blue Notice
Interpol Red Notice and Blue Notice are two different tools used for international cooperation; however, their functions and legal implications differ significantly. A Red Notice is a notification issued to locate a person for the purpose of their provisional arrest and extradition, while a Purple Notice can be used to provide information on modi operandi, which is crucial in such contexts, similar to the functions of an Interpol red notice. It effectively acts as an international warrant for detention, and if the wanted individual is found in one of the member countries, law enforcement agencies can take appropriate measures for their arrest under national legislation.
Unlike it, blue notices do not have legal force for arrest and are used exclusively for gathering further information. They are aimed at establishing the identity, location or obtaining additional details about a person of interest to the investigation. This could be a suspect, a witness, or a victim of a crime. It is important to note that blue notices do not imply any coercive actions, unlike orange notices, which can warn about an imminent threat to public safety and merely facilitate the exchange of data between countries.
Another important difference lies in the nature of the crimes to which these notices are applied. A Red Notice is typically used in cases of serious criminal offenses, such as murder, terrorism, human trafficking, or drug trafficking. Its purpose is to detain individuals accused or already convicted of such crimes and transfer them to the jurisdiction of the requesting country, which could be detailed in the blue notice. Interpol blue notices, on the other hand, cover a broader range of situations, including economic crimes, fraud, and corruption, as well as cases where it is necessary to locate witnesses or missing persons.
Blue notices can also be used in situations where it is necessary to establish the identity or verify the documents of a person suspected of involvement in a crime. For example, if a person uses forged documents or conceals their citizenship, law enforcement agencies may request the publication of Interpol blue notices to determine their true details and ascertain any person’s criminal activities.
From the perspective of legal impact, a Red Notice can serve as grounds for temporary arrest, while Blue Notices are purely informational tools that do not entail any obligations to detain the wanted person. Despite this, both notices play an important role in international law and order, complementing each other depending on the objectives of the investigation.
In the Interpol notices system, there are several types of notifications; however, Interpol blue notices stand out for their flexibility and wide range of applications. They can be used not only to search for wanted persons but also to locate witnesses, victims of crimes, and even missing persons if there are grounds to believe that their disappearance is connected to criminal activity.
Thus, blue notices serve as an important tool for international interaction between law enforcement agencies, helping to exchange information without the need to initiate detention or extradition. Unlike Red Notice, which implies criminal prosecution, Interpol Blue Notices are created solely to obtain additional information, making them a more versatile means within the system of Interpol notices under the framework of the United Nations.
Can an Interpol Blue Notice Be Challenged?
Although an Interpol Blue Notice is not a legal ground for provisional arrest, its publication can lead to serious reputational and legal consequences for the person mentioned in it. Blue notices are widely used by national law enforcement agencies to gather information about unidentified bodies; however, sometimes, their publication may result from improper actions based on erroneous or unreliable data. In such cases, the person for whom the blue notice has been issued may attempt to challenge it and seek its removal, including filing requests regarding United Nations special notices.
If a person is confident that Interpol blue notices were issued unlawfully, contain false information, or violate their rights, they can file a complaint with the Commission for the Control of Interpol’s Files (CCF). This independent body handles complaints and verifies whether the Interpol notice complies with established standards. Challenging is possible in cases where blue notices violate Interpol’s rules, potentially alerting the security council sanctions committees, or if the individual is wanted for political, military, religious, or racial reasons.
To submit an official complaint to the CCF, it is necessary to provide documentary evidence of the unlawfulness of the blue notice. This may include court decisions, official documents, or other evidence confirming that the request for the publication of an Interpol blue notice was submitted without sufficient grounds for a valid criminal investigation. Facts indicating incorrect data, procedural violations, or bias on the part of the initiating state are considered.
The procedure for reviewing complaints in the CCF consists of several stages. First, the commission analyses the received materials and checks whether the published Interpol blue notice complies with Interpol’s rules and international criminal tribunal standards. If the application is justified, the commission sends a request to the country that initiated the publication of the blue notice, asking for clarifications and additional information. If the initiating country cannot provide sufficient arguments, Interpol blue notices may be removed from the organisation’s database.
It is important to consider that the process of challenging blue notices can take a significant amount of time. The review of a complaint by the CCF may last from several months to a year, as each case is analysed in accordance with international norms and the legislation of the member countries of the Interpol notice. Moreover, even if the commission deems the notice unfounded, the final decision on its removal may depend on the actions of the state that initiated the search.
In some cases, cooperation with national courts and international organisations helps to achieve the removal of blue notices. If a court in one of the member states issues a ruling confirming the illegality of the notice, this becomes an important argument when filing a complaint with Interpol. Moreover, working with lawyers specialising in international law increases the chances of successfully challenging Interpol blue notices and protecting the individual’s rights in a criminal investigation.
If a complaint to the CCF does not lead to the desired result, alternative strategies can be used, such as engaging with diplomatic representatives or appealing to international courts. This is particularly relevant in cases where an Interpol notice is used as a tool of political pressure rather than for the purposes of a criminal investigation.
Thus, although it is difficult to challenge Interpol blue notices, it is possible with substantial evidence and competent legal support. The main thing is to promptly gather the necessary documents, involve professional lawyers, and develop a defence strategy that takes into account international norms and the principles of Interpol’s work.
How to Remove Interpol Blue Notice?
The removal of an Interpol Blue Notice is a complex process representing the need for an official request and the provision of substantial evidence. First and foremost, the individual against whom the notice has been issued must submit a request to the Commission for the Control of Interpol’s Files (CCF). This is an independent body that reviews complaints and verifies whether the notice complies with the rules of Interpol notices and international criminal tribunals. The request must detail why the Blue Notice should be removed, supported by legal arguments and documentary evidence, including references to diffusion notice standards.
One of the most convincing grounds for the removal of a Blue Notice is the presence of violations in its publication. If it can be proven that the notice was used for political purposes or had a military, religious, or racial motive, the likelihood of its cancellation increases. In such cases, it is important to provide decisions from international courts proving the fact of unjustified persecution. For example, if national law enforcement agencies used an Interpol Blue Notice to pressure opposition politicians or entrepreneurs, this could serve as grounds for its annulment.

Another strategy for removal is cooperation with the authorities of member states. In some cases, countries that submitted a request for the publication of blue notices may independently withdraw them if the evidence presented convinces them of the notification’s inaccuracy. This is possible if new facts have been uncovered during the investigation, confirming the person’s innocence or their lack of involvement in the case being pursued.
An additional way to remove the blue notices may be to appeal to national courts. If the judicial authorities of a member state issue a decision proving the unreasonableness of the search, it can become a key argument when filing a complaint with Interpol notices, potentially leading to an international alert circulated. A court ruling on the violation of international norms or human rights can significantly increase the likelihood of removing blue notices from the databases of international law enforcement, including United Nations special notices.
It is also worth considering that the process of reviewing requests in CCF can take several months and in complex cases, even a year or more. Therefore, it is important to work with professional lawyers who specialise in international law and interaction with Interpol notices. They will help competently prepare documents, develop an effective defence strategy, and coordinate actions with international law enforcement bodies to remove blue notices in accordance with Interpol’s blue notice.
