A "unique identifier" is described as:

A "unique identifier" in the context of the California Nationwide Multistate Licensing System & Registry (NMLS) refers specifically to the number assigned to an individual as a registered loan originator. This identifier is crucial for various reasons: it ensures that all licensed loan originators can be tracked and identified distinctly within the system. It serves as a means of maintaining transparency and accountability in the mortgage industry, allowing consumers to look up a loan originator's credentials and history.

Unlike personal information such as a driver’s license number, social security number, or IRS identification number, which serve different purposes and are not standardized for tracking loan origination activities, the unique identifier is specifically designated to the loan originator for their professional activities. This helps maintain a clear and systematic approach within the regulatory framework governing mortgage professionals.
