Definition
The Bloomberg Unique ID is a unique identifier for every security and will never be re-used. It is an automatically generated number for Fixed Income, Index, Currency, Municipal, Equity and Mortgage securities. An exception to this is Equity Options. The Unique ID is derived from other security-level data for Equity Options.
Additional Information
ID_BB_UNIQUE is unique to a specific security and not the company. If there is more than one ticker for a company within a country, each will have its own ID_BB_UNIQUE. If there is more than one country listing, each will have its ownID_BB_UNIQUE. The combination of ID_BB_UNIQUE and ID_BB_COMPANY should be used to identify an individual security for Mortgages, Munis, and Indices. The Bloomberg Security ID should be used in combination with ID_BB_COMPANY in order to distinguish between securities of the same company for Munis, Equities, Corporates, Governments and Preferreds. ID_BB_SECURITY is a randomly assigned number. By using these identifiers, the user is able to link all securities with the same issuer or company name whether it is an equity or debt instrument.
