Standard Alphabetical Filing Rules for Individual Names

Rule 1: An individual's name is indexed in this exact order: Surname (Unit 1), First Name (Unit 2), Middle Name or Initial (Unit 3). Rule 2: Prefixes such as De, Del, Dela, San, and Mac are treated as part of the surname (e.g., 'Dela Cruz, Maria P.' is alphabetized under 'D'). Rule 3: Suffixes such as Jr., Sr., and Roman numerals (III) are considered the final indexing unit. Rule 4: 'Nothing comes before something' (e.g., 'Santos, Maria' precedes 'Santos, Maria Elena').

Key Takeaways for Examinees
  • Individual: Surname first, then First name, then Middle initial, then Suffix.
  • Hyphenated surnames are indexed as one single combined unit.
  • Abbreviated names are indexed as if spelled out in full.
Sample Exam Simulation Question

Which of the following names should be filed THIRD in alphabetical order?

A. Dela Cruz, Antonio B.
B. Cruz, Antonio C.
C. De la Torre, Beatrice S.
D. Cruz, Antonio
Concept Rationale: Applying indexing rules: (1) Cruz, Antonio [nothing comes before initial]; (2) Cruz, Antonio C.; (3) Dela Cruz, Antonio B.; (4) De la Torre, Beatrice S. Therefore, 'Dela Cruz, Antonio B.' is filed third.
