Interpol Blue Notice: Meaning, Risks and Legal Defence in the UK

An Interpol Blue Notice (historically called a blue corner notice) is a vital instrument used by law enforcement agencies worldwide to assist in criminal investigations, as one of several types of Interpol notices—including Red notice, Green notice, Yellow notice, Black notice, Orange notice, Silver notice, and Purple notices—the Blue Notice serves a unique purpose in the landscape of international law enforcement. Its primary function is to help member countries collect and share critical crime-related information about a person’s identity, location, or activities when that individual is suspected of involvement in criminal activities.

Unlike Red Notices, which are requests for the arrest and extradition of wanted persons, Blue Notices do not authorise arrest. Instead, they facilitate international police cooperation by enabling law enforcement agencies to track, locate, and gather intelligence on individuals of interest. This collaborative approach strengthens the ability of member countries to address cross-border crime and uphold international law.

Blue Notices play a pivotal role in establishing contacts and connections and are often used for:

The information contained in Blue Notices includes basic biographical details such as name, date and place of birth, photographs, and fingerprints, to help identify persons. The notice may also include a description of potential crimes and suspected locations. It is distributed to all INTERPOL member countries to aid in identification and information gathering.

The primary purpose of a Blue Notice is to assist law enforcement agencies in INTERPOL’s member countries with ongoing investigations. It serves primarily as an intelligence-gathering tool for ongoing criminal investigations, particularly for transnational crimes like fraud, cybercrime, and human trafficking. Blue Notices are typically issued for individuals who are subjects of ongoing investigations, such as suspects, witnesses, or victims whose whereabouts are unknown, or persons of interest in legal matters.

Blue Notices can be issued for different categories of individuals, particularly those who may pose a risk or require identification across jurisdictions, including:

In the UK, the National Crime Agency (NCA) hosts INTERPOL’s National Central Bureau, so Blue Notices are handled by the NCA and other law enforcement bodies, particularly when the notice overlaps with a domestic criminal investigation.

The issuance of an Interpol Blue Notice follows a structured process to ensure accuracy and adherence to international standards. The process begins with a request sent to INTERPOL’s General Secretariat by a member country’s National Central Bureau (NCB) or by an authorised international entity, such as the International Criminal Court (ICC). The request includes:

Upon receiving the request, the General Secretariat reviews the information to ensure it complies with INTERPOL’s rules, including safeguards against misuse for political or other wrongful purposes. If the request for a Blue Notice is approved, a new international alert notice is created and distributed to all INTERPOL member states.

UK authorities may be informed through:

Although a Blue Notice does not constitute an arrest warrant, it may trigger:

Being subject to a Blue Notice may also lead to involvement in legal proceedings, because the authorities that receive the information may use it in their own investigations. Individuals should consider engaging a skilled legal team to respond appropriately, challenge the notice and protect their rights. In addition, if an arrest warrant is later issued, the requesting country may apply for an Interpol Red Notice.

As with other INTERPOL notices, misuse or politically motivated issuance can occur, making legal guidance essential.

Interpol is committed to upholding human rights standards in its operations, including the issuance and management of Blue Notices. Article 3 of its Constitution prohibits any activity of a political, military, religious or racial character, and Article 2 refers to the spirit of the Universal Declaration of Human Rights. The Commission for the Control of INTERPOL’s Files (CCF) is an independent body that checks whether INTERPOL’s processing of personal data, including notices, complies with its rules.

If an individual believes that a Blue Notice has been issued in violation of their human rights, they have the right to seek redress through the CCF. In such cases, having legal representatives with expertise in international law and human rights is crucial to effectively challenge the notice and protect the individual’s interests.

Challenging an Interpol Blue Notice is a complex process that requires a deep understanding of both Interpol’s internal rules and the broader framework of international law. Individuals who believe a Blue Notice has been wrongly issued against them must compile compelling evidence to demonstrate that the notice is unjustified, inaccurate, or infringes upon their human rights.

The challenge process involves submitting a formal request to the CCF — since 26 March 2026 through its online portal — accompanied by all supporting documents. The CCF reviews whether the notice complies with INTERPOL’s Constitution and rules; under the CCF Statute, a decision on a deletion request is due within nine months of the request being declared admissible.

Legal assistance is essential at every stage, as experienced lawyers can help prepare a strong case, ensure all documentation is in order, and advocate effectively with Interpol and relevant member countries to seek the removal of the notice.

Securing the removal of an Interpol Blue Notice is a detailed and often lengthy process that demands careful legal strategy. Once issued, a Blue Notice remains in INTERPOL’s databases until it is cancelled — for example because the requesting country withdraws it or its purpose has been achieved — or until it is deleted following a successful application to the CCF.

The removal process usually begins with a detailed request explaining why the notice should be withdrawn—this could be due to the resolution of the underlying criminal investigation, a court decision finding the notice improper, or evidence that the notice breaches Interpol’s rules. The CCF will review the submission, possibly requesting further information from the requesting country or the individual concerned before making a final decision.

Achieving the removal of a Blue Notice can restore an individual’s legal status, improve their ability to travel, and protect their reputation, underscoring the importance of obtaining professional legal assistance throughout the process.
