How is a UTC identified?

• A. Five-character alphanumeric code in uppercase excluding I and O
• B. Four-digit numeric code
• C. Three-letter code
• D. Six-character alphanumeric including I and O

Answer: (A)

UTCs are identified by a five-character, uppercase alphanumeric string with the letters I and O excluded to prevent confusion with the digits 1 and 0. This fixed length and restricted character set make UTCs easy to recognize, compare, and manage across planning and execution. It isn’t a numeric-only code, isn’t a three-letter code, and isn’t six characters long with I or O included. For example, a valid UTC might look like W3A9B or 7K2X5.
