HomeINTERPOL currently has 196 member countries, making its police cooperation network one of the broadest in the world. Each member maintains a National Central Bureau (NCB), which acts as the contact point between its national law-enforcement authorities, other member countries and the INTERPOL General Secretariat.
Thailand is an INTERPOL member country. It has been a member since 1951, and its National Central Bureau is located in Bangkok.
Below is the current list of INTERPOL member countries based on INTERPOL’s official membership records.

How Does INTERPOL Membership Work?
Membership is governed by Article 4 of the INTERPOL Constitution and related rules adopted by the General Assembly. INTERPOL states that Article 4 establishes both the criteria and the process for membership, with additional clarification adopted by the General Assembly in 2017.
INTERPOL’s membership has expanded substantially over time. The organization had 100 member countries by 1967, 150 by 1989, and reached its current total of 196 in 2023.
Once a country participates in the organization, its National Central Bureau becomes the principal national contact point for cooperation through INTERPOL.
For a broader explanation of the organization itself, its structure and its international police-cooperation system, see how INTERPOL works.
What Is a National Central Bureau?
NEvery INTERPOL member country hosts a National Central Bureau (NCB). The NCB connects national law-enforcement authorities with other NCBs and the INTERPOL General Secretariat through INTERPOL’s secure communications network.
The precise institutional structure differs from country to country because each NCB is staffed and operated within the member’s national law-enforcement system.
In Thailand, the official INTERPOL member-country record identifies the NCB in Bangkok. Thailand has participated in INTERPOL since 1951.
Does INTERPOL Have Jurisdiction in All Member Countries?
INTERPOL membership does not turn the organization into a supranational police force with independent powers inside each member country.
INTERPOL provides the infrastructure through which national police authorities can exchange information, access databases and cooperate internationally. Domestic law-enforcement authorities remain responsible for actions taken within their own jurisdictions, and INTERPOL itself states that its activities operate within the limits of the laws applicable in individual countries.
This distinction is important when considering arrest, criminal proceedings or extradition. Being an INTERPOL member country means participating in the cooperation network; it does not make every international request automatically enforceable under domestic law.
Is Thailand an INTERPOL Member Country?
Yes. Thailand is a member of INTERPOL and has been since 1951. Its National Central Bureau is located in Bangkok and connects Thai law-enforcement authorities with INTERPOL’s international network.
INTERPOL membership and extradition law should nevertheless be treated as separate issues. Whether a person can be extradited from Thailand depends on the applicable Thai law, treaty framework and circumstances of the request rather than on INTERPOL membership alone.
For information specifically about surrender proceedings and international requests involving Thailand, see our guide to extradition from Thailand.
Are All Countries Members of INTERPOL?
No. Although INTERPOL has 196 members and therefore covers most of the world, membership is not universal. The organization maintains its own official membership list under its constitutional framework.
For the opposite search intent, see our separate guide to countries that are not members of INTERPOL.
INTERPOL Membership and International Police Cooperation
Membership gives national police authorities access to INTERPOL’s international cooperation infrastructure, including its secure I-24/7 communications network and police databases. Each country participates through its own NCB and acts according to its national legal system.
For individuals involved in a cross-border criminal matter, the practical consequences therefore depend on more than the simple fact that two countries belong to INTERPOL. The type of international request, domestic legislation and any applicable extradition arrangements must be considered separately.
