A unique identifier is an identifier that is assigned to one individual or entity, is associated with all the data for that individual or entity in a data system or dataset, and remains the same over time, i.e., it “follows” that individual or entity. Unique identifiers can be used to link data within a data system or dataset or across more than one data system or dataset.
