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. IID is the system of record for all UCSF identities.


The Individual Identifier system 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
  • 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
  • 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.
