A Numerical Identifier is a unique number assigned to an object, person, or entity to distinguish it from others. This identifier helps in organizing and managing data efficiently, making it easier to retrieve and reference specific items. Common examples include Social Security Numbers, ISBNs for books, and employee IDs. These identifiers are crucial in various fields, including finance, healthcare, and education. They ensure accuracy in record-keeping and facilitate communication between systems. By using a numerical identifier, organizations can streamline processes and reduce the chances of errors in data management.
