What is AP style?
AP style refers to the editing conventions published by The Associated Press in its stylebook. Journalists, PR writers and many businesses follow these rules to standardize capitalization, abbreviations, numbers and punctuation. For example, AP style spells out numbers one through nine and uses figures for 10 and above, so a press release reads "three vendors" but "25 employees."
Why does AP style matter?
AP style gives writers a shared playbook, so decisions that would eat up meeting time get settled by a quick reference check. It also sends a quiet signal of credibility, because readers trust copy that reads cleanly and predictably. For brands working with journalists, matching AP style makes press releases easier to pick up without heavy editing.
Examples of AP style
Numbers — Spell out one through nine, then switch to figures, so a press release reads "six products" but "15 customers."
Oxford comma — AP drops the comma before "and" in simple lists, giving "fast, flexible and affordable" with no final comma.
Dates — Abbreviate months of five or more letters when a specific day appears, so "Jan. 5, 2026" in news copy but "January 2026" when no day is given.
