1. The First Code: This code consisted of the Kanji characters "Ten" (heaven) and "Chi" (earth), symbolizing the two parts of the Sage's eyes.
2. The Second Code: This code was made up of a series of numbers representing the locations where the eyes were hidden. These locations included Mount Myōboku, Mount Katsuragi, and Mount Kurama.
3. The Third Code: This code consisted of a series of symbols representing the guardians who protected the eyes. These guardians included the toad elder of Mount Myōboku, the white snake sage of Ryūchi Cave, and the monkey king of Mount Kifusashi.
By combining these three codes, Jiraiya was able to convey the existence and location of the "Eyes of God" to Minato, ensuring that this vital information would be protected from enemies.
