The name Jaddai in Hebrew letters is ידו. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
ידו
In short
Your name in Hebrew letters is ידו. A Tanakh name: an Israelite (first in Ezra 10:43; 3 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “praised”. Adding up the numbers of its letters gives 20 — the same as the Torah word היה, “to be, become”. That number points to Torah page 20 of 354 — in the portion Lech Lecha. What that portion is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision. The verse that begins with the first letter of your name and ends with the last is Genesis 9:27. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Jaddai” — this exact spelling is what was calculated: ידו. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name ידו gives 20.

Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
with finals and ordinal — 20. A Torah word with the same number is היה — “to be, become” (Genesis 1:2).
Reduced, each letter to one digit (mispar katan) — 11. A Torah word with the same number is חג — “festival” (Exodus 10:9).
Cumulative: a letter plus all letters before it (mispar kidmi) — 86. A Torah word with the same number is אלהים — “God” (Genesis 1:1).
Squares of the letter values (mispar perati) — 152. A Torah word with the same number is נקב — “to designate, pierce” (Genesis 30:28).
Building: the sum grows with each letter (mispar bone’eh) — 44. A Torah word with the same number is ילד — “to bear, give birth” (Genesis 3:16).
The letters that come out are מקפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 220. A Torah word with the same number is טהור — “pure, clean” (Genesis 7:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 466. A Torah word with the same number is שמעון — “Simeon, son of Jacob” (Genesis 29:33).

יפת אלהים ליפת וישכן באהלי שם ויהי כנען עבד למו
