The API code used for rated aviators is of what type?

• A. Alphabetic
• B. Numeric
• C. Alphanumeric
• D. Textual

Answer: (B)

Numeric codes are used for API codes assigned to rated aviators because digits provide a simple, unambiguous, machine-friendly identifier. They are easy to store, sort, validate, and transmit across aviation records systems, and they minimize confusion from similar-looking characters that can occur with letters or mixed alphanumeric strings. Using only numbers also supports fixed-length formats and straightforward validation, which is harder to achieve with alphabetic, alphanumeric, or textual codes.
