Identification Numbers for each Entity in the Master Index

Each object profile in a master index application is assigned a unique identification number in addition to the local IDs assigned by individual systems. Each object has one unique identification number throughout your organization and a unique identification number within each system with which they are registered.

EUID

Every object profile in the master index system is assigned an enterprise-wide unique identification number. This number is the same for that object regardless of the system from which the object information originates. This number is called the enterprise-wide unique identifier (EUID) and is used to cross-reference object profiles in order to accurately identify the objects throughout your organization.

Local ID

A local ID is a unique local identification number that is assigned to an object in each system at which it is registered. These numbers are assigned using a numbering system unique to each local system, and are used internally by the systems to identify each object. A master index application uses an object’s EUID to cross-reference its local IDs in different systems. Note that the name of the Local ID field is configurable and might be different for your implementation.

Auxiliary ID

An auxiliary ID is an identification code that does not necessarily uniquely identify a single object within the database, but might identify a group of objects. For example, if a family shares the same account or insurance policy, every family member would have the same identification code for that account or policy.
