*Unique identifier: Constituents: the basic number is eight characters (alphanumeric) in length but excludes vowels (A, E, I, O, U) and the letter Y, and zero shall not be the first character. The basic number shall be randomly generated and semantically meaningless. A DTI and DLI are unique from each other and displayed using capital letters.

**Latin: Based on ISO/IEC 2382 definition of “alphanumeric” (pertaining to data that consist of letters, digits, and usually other characters, such as punctuation marks, as well as to processes and functional units that use those data). Supported characters include: Latin letters, numbers, common symbols (@, #, !, $, %, &, *, (, )) punctuation( ., ,, -, _, ?, !, :) and ‘Space’.
