423 (variations: 4/23, 4:23, or "for the fold, number three") is a recurring number in the ARG. Due to its frequent and sometimes clever use, as well as its origin, it has been deemed significant to the story, and is believed to be an important clue.
Instances of 423 will be listed in chronological order below. The numbers 4, 2, and 3 will also be listed if they appear in close proximity to each other.
