Interpol Notices Explained: Red, Blue, Green & More
In short: Interpol notices are international cooperation requests circulated among Interpol’s 196 member countries — not arrest warrants. Interpol itself has no police officers and cannot arrest anyone. There are eight color-coded notice types (Red, Blue, Green, Yellow, Black, Orange, Purple, and the INTERPOL–UN Security Council Special Notice), plus a separate, less-scrutinized alert called a diffusion. Only a fraction of Red Notices appear on any public list; most Interpol data is not public.
What are Interpol notices?
Interpol notices are formal international requests for cooperation or alerts that let police forces in Interpol’s member countries share critical crime-related information. A notice is not a warrant, and it does not by itself authorize an arrest. Interpol is an information-sharing organization; it has no agents, no jurisdiction, and no power to compel any country to act.
The International Criminal Police Organization (Interpol) connects 196 member countries through a secure network. Each country runs a National Central Bureau (NCB) that submits notice requests to Interpol’s General Secretariat in Lyon, France. The Secretariat reviews a request against Interpol’s own rules — in particular Article 2 (respect for human rights) and Article 3 (a strict ban on interventions of a political, military, religious, or racial character) of the Interpol Constitution — before a notice is published.
Key fact: Interpol cannot arrest anyone. Only national police, acting under their own domestic law, can detain a person — and whether they do so in response to a notice is entirely their decision.
Because notices carry real consequences — border stops, visa refusals, frozen bank accounts, blocked employment — understanding which notice you face, and on what basis it was issued, is the first step in responding.
The Interpol color-notice system
Interpol operates eight notice categories, seven identified by color plus one special notice. Each serves a distinct purpose and produces a different practical effect. The table below summarizes all of them.
| Notice | Purpose | Practical effect |
|---|---|---|
| Red Notice | Seek the location and arrest of a person wanted for prosecution or to serve a sentence | Requests provisional arrest pending extradition; the most serious notice for the individual |
| Blue Notice | Collect additional information about a person’s identity, location, or activities in a criminal investigation | Person may be traced, questioned, or monitored at borders; often precedes a Red Notice |
| Green Notice | Warn about a person who has committed offenses and is likely to repeat them in other countries | Acts as an international “watch” alert; can trigger heightened scrutiny and denied entry |
| Yellow Notice | Help locate missing persons (often minors) or identify people unable to identify themselves | Used in missing-person and identity cases; not accusatory |
| Black Notice | Seek information on unidentified bodies | Used to identify deceased persons; not directed at a living subject |
| Orange Notice | Warn of an event, person, object, or process posing a serious and imminent threat to public safety | Alerts authorities to dangers such as weapons or concealed devices |
| Purple Notice | Seek or provide information on criminal methods, objects, devices, and concealment techniques | Intelligence-sharing about modus operandi; not aimed at a named individual |
| INTERPOL–UN Security Council Special Notice | Alert to groups and individuals subject to United Nations Security Council sanctions | Flags sanctioned persons/entities; tied to UN sanctions regimes |
For most people who contact us, the notices that matter are the Red Notice — the one that asks countries to arrest — and the Blue Notice, which is frequently the quieter early sign that an investigation is targeting you. If a Red Notice is in play, treat it as urgent: provisional arrest can happen at a border crossing before any formal extradition request is even filed.

Red Notice vs. diffusion — what’s the difference?
A Red Notice is published by Interpol’s General Secretariat after review; a diffusion is an alert sent directly from one member country’s NCB to others, without the same central vetting. Both ask police to locate and provisionally arrest a person, but a diffusion typically receives less oversight before it circulates — which is precisely why it can be easier to misuse.
The practical differences matter:
- Origin. A Red Notice request goes to Lyon, where the Secretariat’s Notices and Diffusions Task Force checks it against Interpol’s rules before publication. A diffusion is transmitted country-to-country over Interpol’s network and can reach other bureaus almost immediately.
- Review timing. Red Notices are screened before they go live. Diffusions are often reviewed after they are already circulating, meaning a flawed or politically motivated alert can cause harm before anyone examines it.
- Visibility. A person can be subject to a diffusion without any corresponding public record — making them harder to detect and, in some ways, harder to challenge until they surface at a border.
The good news is that the remedy is the same for both. The Commission for the Control of Interpol’s Files (CCF) reviews challenges to Red Notices and diffusions alike. If you want the full picture of how the most serious alert works — how it is requested, what it does, and how it is removed — see our detailed guide to the Interpol Red Notice process.
Is there a public “Interpol wanted list”?
There is no comprehensive public “Interpol wanted list.” Interpol publishes public extracts of some Red Notices on its website — but only when the requesting country agrees to make that notice public. The vast majority of Interpol’s notice and diffusion data is not public and is accessible only to law-enforcement authorities.
This surprises many people. Searching Interpol’s public “Red Notices” page and finding nothing does not mean you are clear. A Red Notice can exist against you while being withheld from public view, and a diffusion may never appear publicly at all. The public list is a curated shop window, not the full database.
Key fact: Appearing on no public Interpol list is not proof that no notice or diffusion exists. Only a formal data-access request to the CCF can confirm what Interpol holds about you.
That is also why relying on unofficial “Interpol Red Notice list” or “Interpol wanted list” search sites is risky: they only mirror the small public subset, they are often out of date, and they cannot see non-public records. To know your true status, you have to ask Interpol directly — through the channel below.
How to check if you have an Interpol notice
To find out whether Interpol holds data about you, submit a request to the Commission for the Control of Interpol’s Files (CCF), the independent body that controls access to and correction of personal data in Interpol’s systems. The CCF’s Requests Chamber handles access requests free of charge, and you can file one yourself or through counsel. Follow these steps:
- Gather your identity documents. Prepare a copy of a valid government-issued photo ID (passport or national ID). The CCF requires this to confirm your identity and prevent disclosure to third parties.
- Prepare your request. State clearly that you are requesting access to any data concerning you in Interpol’s files. Include your full name, date and place of birth, nationality, and contact address.
- Submit to the CCF. File the request through the CCF’s official channel — the online request form or postal address published on Interpol’s website. There is no fee for an access request.
- Await acknowledgment. The CCF confirms receipt and assigns your request a reference number. Keep this number for all follow-up.
- Receive the CCF’s response. The Commission reviews Interpol’s files and informs you whether data concerning you is held, subject to the consent rules of the country that supplied the information.
- Assess your options. If data exists, you can move from an access request to a correction or deletion request — the challenge process described in the next section.
Because timelines can run to several months and the wording of a request materially affects the outcome, most clients ask a lawyer to prepare and file it. A carefully framed request preserves your right to escalate to a full challenge without tipping off the requesting country prematurely.
What to do if a notice affects you
If an Interpol notice or diffusion is harming you, you have the right to challenge it before the CCF and request that Interpol correct or delete the data. Grounds for removal include violations of Article 3 (political, military, religious, or racial cases), Article 2 (human-rights concerns), lack of a proper legal basis, expired or predominantly political prosecutions, and failures to respect Interpol’s data-processing rules.
A challenge is a legal argument, not a form-filling exercise. It typically requires you to:
- Establish that the notice or diffusion targets you and pin down its likely basis;
- Marshal evidence that the underlying case is politically motivated, abusive, procedurally defective, or otherwise contrary to Interpol’s rules;
- Present that argument to the CCF’s Requests Chamber, which can recommend deletion of the data from Interpol’s systems.
The CCF’s decisions on deletion are binding on Interpol, which makes a well-built challenge genuinely powerful. But the standard of proof is demanding and you usually get one strong opportunity to make your case.

If your matter also involves possible surrender to American authorities, an Interpol notice is often the visible edge of a larger extradition effort. Understand how the two connect in our overview of extradition to the United States, and act early — provisional arrest can precede a formal request.

Frequently asked questions
Is an Interpol notice the same as an arrest warrant?
No. A notice is an international request for cooperation. The underlying arrest warrant is issued by a national court in the requesting country. Interpol has no power to issue warrants or to arrest anyone; only national police can detain you under their own law.
Which Interpol notice is the most serious?
The Red Notice, because it asks member countries to locate and provisionally arrest a person pending extradition. A Blue Notice is less severe but often signals that an investigation is closing in and a Red Notice may follow.
Can I see if I’m on an Interpol list online?
Only partly. Interpol publishes public extracts of some Red Notices, but most notices and all diffusions are not public. The reliable way to learn your status is a data-access request to the Commission for the Control of Interpol’s Files (CCF).
What is an Interpol diffusion?
A diffusion is an alert sent directly between member countries’ National Central Bureaus, rather than published centrally by Interpol’s General Secretariat. It requests similar action to a Red Notice but generally undergoes less prior review.
Does a Blue Notice mean I will be arrested?
Not directly. A Blue Notice seeks information about your identity, location, or activities in an investigation. It can, however, lead to questioning or border scrutiny and sometimes precedes a Red Notice, so it should be taken seriously.
How long does a CCF request take?
Processing times vary and can extend to several months, depending on the request’s complexity and whether the country that supplied the data must be consulted. The CCF assigns a reference number so you can track your matter.
Can an Interpol notice be removed?
Yes. If a notice or diffusion breaches Interpol’s rules — for example Article 3 on political matters or Article 2 on human rights — the CCF’s Requests Chamber can order it deleted from Interpol’s systems. A well-evidenced challenge is the route to removal.
Can Interpol operate inside the United States?
Interpol does not conduct arrests in the United States or anywhere else. US authorities decide independently whether to act on a notice under American law, typically involving the Department of Justice. Interpol’s role is limited to sharing information.
