Alphanumeric notation

Alphanumeric notation combines letters and numbers to identify or categorize information systematically. It’s commonly used in settings like coding, labeling, or referencing items, where letters might represent categories or types, and numbers provide specific identifiers within those categories. For example, in product codes like "A12," "A" might denote a product line, while "12" specifies the individual item. This system improves clarity, organization, and communication by allowing quick, precise identification of items, locations, or data, especially when dealing with large or complex sets of information.
