What is the format of a Document Number used to identify a document?

• A. A 14-digit alphanumeric number used to identify a document, for example, W80TDS73450051.
• B. A 12-digit numeric code
• C. A 10-character alphanumeric string
• D. A 16-digit hexadecimal value

Answer: (A)

Document numbers use a 14-character alphanumeric string to uniquely identify each document, allowing a wide range of letter-and-number combos. The example W80TDS73450051 demonstrates this exact length and mix of characters, which is why this format is the best fit. A purely numeric code would be too limited in combinations, and a shorter 10-character string wouldn’t match the length shown. A 16-digit hexadecimal value would be restricted to digits 0–9 and letters A–F only, which wouldn’t accommodate the broader letter set seen in the example. Therefore, the 14-character alphanumeric format best matches how a document is identified.
