What is the real meaning of Red Notice?

A Red Notice is an Interpol alert requesting law enforcement to locate and arrest an individual for extradition, but it isn’t legally binding — each country decides how to treat it.

An Interpol Red Notice is an international alert to locate and arrest an individual for subsequent extradition. While it does not carry the legal weight of an international arrest warrant, it is widely used by law enforcement agencies as a basis for temporarily detaining the wanted individual. Each country decides whether to treat it as binding. The notice is issued at the request of one of Interpol’s member countries and includes details about the crime, the wanted individual, and their presumed whereabouts, as well as a national arrest warrant or court order.
