About Notices

Our colour-coded Notices enable countries to share alerts and requests for information worldwide.

INTERPOL Notices are international requests for cooperation or alerts allowing police in member countries to share critical crime-related information.

Notices are published by the General Secretariat at the request of a National Central Bureau and are made available to all our member countries. Notices can also be used by the United Nations, International Criminal Tribunals and the International Criminal Court to seek persons wanted for committing crimes within their jurisdiction, notably genocide, war crimes, and crimes against humanity.

Most Notices are for police use only and are not made available to the public. However, in some cases, for example to alert the public, or to request help from the public, an extract of the Notice can be published on this site. United Nations Special Notices are public.

INTERPOL's system of colour-coded Notices

Types of Notice

Red Notice: To seek the location and arrest of wanted persons wanted for prosecution or to serve a sentence.

Yellow Notice: To help locate missing persons, often minors, or to help identify persons who are unable to identify themselves.

Blue Notice: To collect additional information about a person’s identity, location or activities in relation to a crime.               

Black Notice: To seek information on unidentified bodies.

Green Notice: To provide warning about a person’s criminal activities, where the person is considered to be a possible threat to public safety.

Orange Notice: To warn of an event, a person, an object or a process representing a serious and imminent threat to public safety.

Purple Notice: To seek or provide information on modus operandi, objects, devices and concealment methods used by criminals.

INTERPOL–United Nations Security Council Special Notice: Issued for groups and individuals who are the targets of UN Security Council Sanctions Committees.       

Notices must meet legal criteria

A Notice is only published if it complies with INTERPOL’s Constitution and fulfils all conditions for processing the information as defined by our Rules on the Processing of Data. This ensures the legality and quality of information, and the protection of personal data.

For example, a Notice will not be published if it violates Article 3 of INTERPOL’s Constitution, which forbids the Organization from undertaking any intervention or activities of a political, military, religious or racial character.

The legal basis for a Red Notice is an arrest warrant or court order issued by the judicial authorities in the country concerned. Many of our member countries consider a Red Notice to be a valid request for provisional arrest.

Any individual who is subject to an INTERPOL Notice should be considered innocent until proven guilty.

Diffusions – less formal

Member countries may also request cooperation from each other through another alert mechanism known as a 'diffusion'. This is less formal than a notice and is circulated directly by an NCB to all or some of our member countries. Diffusions must also comply with INTERPOL’s Constitution and the Rules on the Processing of Data.
