The Individual Identifier System (IID) acts as a clearing house for identities, matching identity qualifying information ensuring that each person has one and only one identity record keyed by a unique UCSF identity number.

UCSF perceives administrative value in identifying unambiguously those individual who have a relationship to the campus. The purpose of the Individual Identifier System is to manage the assignment to each such person of a single unique identifier, the UCSF Identity Number, and to enable recognition of that individual as the same person across a number of application databases and systems.


IID is comprised of the Individual Identifier Database and a set of programs which enable on-line maintenance of and inquiry on that database. The purpose of the system is to provide a repository for information which identifies uniquely every individual who has a significant relationship with the UCSF campus.

The core functionality of the system consists of basic identity tracking, including identity matching, unique identifier assignment, and identity qualifier maintenance. Additional ancillary functionality has appended to IID over time, including affiliation tracking (for individuals not in the Employee, Student, or Fellows databases), campus locator system functions, authorization of campus id cards, authorization and processing of recharge of campus id cards, and authorization of access to physical space.

IID interfaces with the Payroll/Personnel System, the Residents and Fellows System and the Student Information System. Individuals who have records in these source systems also have a record in the Individual Identifier System and the value of the identifier is the same for a given individual across all three systems. Individuals associated with UCSF who do not have a record in one of these source systems are entered directly into IID as Affiliates.
