Writing & StyleStyle guide

Alphabetical Lists

Alphabetical ordering is most useful for reference-style lists where readers search by name and there is no stronger sequence. House styles can define details such as how number-leading entries are ordered, so document-specific rules still matter.

Quick answer

Alphabetize unordered lookup lists when name-based scanning is the useful order; keep procedural, chronological, or priority lists in their meaningful order.

Important caveats

House Style Boundary

GOV.UK documents a specific alphanumeric convention: number-leading entries before letter-leading entries, with numbers ordered numerically.

Order Boundary

Alphabetical order is useful when readers look up items by name and no process, priority, or chronology controls the order.

Sequence Boundary

Do not alphabetize a procedure or prioritized list merely for visual neatness; sequence or priority should control those lists.
