证券，都需要有个标识。比如说国内的股票，大家都习惯于用6位数字来表示，而且这个标识是大家都能认可的，比如600600就代表青岛啤酒。但是，在不同的国家或地区，这些标识千差万别，那么在设计交易系统时，我们如何来取舍这些标识呢。一般的原则就是将几种业界常见的标识都记录下来：

symbol（ticker）, CUSIP, ISIN, SEDOL, RIC, WPK, bloomberg code, 可能额外还有一个公司内部的统一编码

那这些标识到底都是什么意思呢？为了避免重复劳动，我直接别的网站摘录过来，其中包括symbol, CUSIP, ISIN, SEDOL和RIC的说明。

SYMBOL / TICKER / TICKER SYBMOL / STOCK SYMBOL

The SYMBOL is another unique identifies used to represent a particular security listed on an exchange or  traded publicly. Very commonly used for trading, market data and other places. All listed securities have  unique ticker symbol.

Some examples are: IBM, MSFT, GE etc.

ISIN

ISIN stands for ”International Securities Identification Number”. It is used to uniquely identifies a security. It is originated from ISO 6166. ISIN is used to identify bonds, commercial paper, equities, warrants and most of the listed derivatives. The ISIN code is a 12 character alphanumerical code.

One distinction is that ISIN code doesn’t change by exchange or currency it trades. It is unique unlike symbol that may change based on exhcnage and currency.

To distinguish the exchange it has the same ISIN on each, though not the same ticker symbol. ISIN cannot specify a particular trading location in this case, and another identifier, typically MIC or the three-letter exchange code, will have to be specified in addition to the ISIN. The SEDOL board of the London Stock Exchange has revised their own standards to address this issue.

Example: LT0000610040

CUSIP

The CUSIP number or simply a CUSIP is another key identifier used finanical marketsm to uniquely identify the company or issuer and the type of security.
CUSIP stands for “Committee on Uniform Securities Identification Procedures”.  The CUSIP number is mainly used for US and Canadian stocks, and US government and municipal bonds.

The CUSIP number is nine characters wide and its a combination of letters and numbers. The first six characters identify the issuer and are assigned in an alphabetical fashion; the seventh and eighth characters identify the type of issue; and the last digit is used as a check digit.

The CUSIP Service Bureau is operated by Standard & Poor’s on behalf of the American Bankers Association (ABA). You can learn more at http://www.cusip.com.

Example: 008000AA7 (more examples)

SEDOL

The SEDOL is used for all securities trading on the London Stock Exchange and other exchanges in the U.K. The SEDOL stands for “Stock Exchange Daily Official List” and it is seven characters wide. It is combination of letters and numbers.

Generally used to identify the UK securities that are not traded in US. Unique code is issued for each market  the security is listed on.  You should also know about MIC that is used to identify Markets(exchanges).

Example: B0WNLY7

RIC Code

The RIC stands for ”Reuters Instrument Code”,used by Reuters to identify financial instruments and indices. The codes are used for looking up information on various Reuters financial information networks.

RIC code is mainly two parts. First part is a symbol and second part is exchange code which is optional. Second part is separated by period.

Example: MSFT.OQ representst the Microsoft on NASDAQ.

而WPK（或者WKN, WPKN, Wert）是德国证券标识代码。In Germany the securities identification number (WKN) is a six-figure number. The International Security Identification Number (ISIN) is a worldwide classification index that was also introduced as a standard in Germany in 2003. The WKN is included in the German ISIN. The twelve-digit ISIN is made up of a two-digit country code, a nine-digit national code and a verification code. The WKN is included in the sixth to eleventh digit.

 

VALOR numbers

The VALOR number is a code which uniquely identifies listed securities and financial instruments used in Switzerland, and serve a similar purpose to CUSIP or WKN in the North American or German markets respectively.

 

MIC

此外，上文中提到的MIC，是market identifier code的缩写，属于ISO 10383，主要用来标识交易所。http://www.iso15022.org/MIC/homepageMIC.htm

MIC一般用四位字母来标识，比如上海证券交易所对应的mic就是XSHG。
