This code allows each entity to be identified by number instead of a name in the global database of searchable entities, as multiple entities may have identical names. These entities can be searched by number rather than names, as many entities may have the same or similar names. The LEI code is given as per ISO (International Organization for Standardization) benchmarks. This code is now a legal necessity within the international financial system for many companies.
