Data exchange

As national boundaries become increasingly meaningless to criminals, effective and timely police communication across borders is more important than ever before. At INTERPOL, one of our priorities is to enable the world’s police to exchange information securely and rapidly.

Two tools deliver this aim:

I-link: taking data exchange to the next level


Every day, law enforcement officers in member countries around the world exchange thousands of messages, often urgent, using I-24/7. The effective management of these messages is vital.

I-link is a unique and dynamic operational system that centralizes and continually enhances database features. It will also help make connections between seemingly unrelated investigations, by identifying common threads. Officers in National Central Bureaus (NCBs) and other authorized users are able to access I-link through the I-24/7 network.

Key features


  • Provides an international structured communication standard, ensuring consistency and operational relevancy of recorded and exchanged police data.
  • Offers adaptable structured forms enabling national systems to seamlessly transmit information, thereby increasing the quality and the quantity of information available.
  • Enables the direct recording of police information into INTERPOL’s criminal database, eliminating information processing times.
  • Grants immediate access to real-time police information.
  • Is available in all four of INTERPOL's official languages: Arabic, English, French and Spanish.

Instant international alerts

All international alerts for wanted persons – either in the form of an INTERPOL Red Notice or Diffusions – are now submitted through I-link. In a matter of seconds, member countries can draft and submit an alert seeking the arrest of a wanted criminal, with the information recorded instantly into the Organization’s central database and immediately accessible to police around the world.

Three other types of Notices are also available through I-link: Yellow, Green and Blue (for missing persons, warnings and seeking additional information, respectively).
