What is an alphanumeric system?

• A. It uses only alphabetical names with no numbers.
• B. It uses a combination of names and numbers, or subject headings and numbers, with sequential filing of numbers.
• C. It uses only numeric categories with no names.
• D. It avoids sequential filing.

Answer: (B)

An alphanumeric system uses both letters and numbers to organize records. This approach lets you pair a descriptive element (such as a subject heading or a person’s name) with a numeric sequence, so items can be filed by category and then in the order they were created. In practice, you might see codes like TRAFFIC-001 or CR-2024-022, where the letters indicate the category and the numbers give a unique, sequential identifier. That combination makes it easier to retrieve and sort files, reports, or dockets, especially when the volume grows. The reason this is the best answer is that it explicitly uses both alphabetic characters and numeric digits together and relies on numbers filed in sequence to preserve order. Other schemes that use only letters would lack the numeric sequencing needed for ordering, while systems that use only numbers would lose the descriptive category. And avoiding sequential filing would remove the predictable order that makes finding and tracking records straightforward.
