A popular ISIN prefix is the "XS" ISIN code, commonly referred to as the international ISIN code as its the ISIN code used for clearing and settlement purposes by Euroclear and Clearstream in Europe. These two banks are the international central depository, or international central securities depository (ICSD) which help settle and clear medium term notes, long term notes and many other types of debt securities.

An XS ISIN is distinguishable from local or standard ISINs such as those that begin with CN (China) or KY (Cayman Islands).  ISINs with a XS designation are primarily assigned in order to clear and settlement trade in the international central securities depositories of either Euroclear, Clearstream or both.

Varying securities use an ISIN for clearing and settlement, namely medium term notes (MTN), long term notes (LTN), global notes and securities, standalone debt and more.
