What do the last two digits of the WP number identify?

• A. New WPs issued as changes or revisions that logically fit between existing WPs
• B. The initial manual WPs 001 through 999
• C. The prefix
• D. The general subject classification

Answer: (A)

The two-digit suffix on a WP number acts as a revision/insert indicator. It lets new or revised WPs be issued that fit between existing ones without changing the base numbers, preserving a clear sequence and history of updates. The base numbers (001 through 999) identify the original WPs, while the prefix points to the general subject area. So the last two digits specifically track revisions that slot between established WPs, rather than signaling the original set or the subject category.
