Bonds and stocks usually have a unique identifying number, issued by a clearing house or other agency. In the U.S., this is the CUSIP number (see "CUSIP"). In Europe it is the Common Code, issued in Luxembourg (which replaces CEDEL and Euroclear codes). The Japanese use SICC, the Swiss use Valoren, the British use the SEDOL, the Germans use WKN (Wertpapier Kenn-nummer). To find others, see the list posted at the bottom of the "Definitions" page posted by Ci: Corporate Information (www.corporateinformation.com/defext.asp).
