The name Zaccai in Hebrew letters is זכי. 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.
זכי
In short
Your name in Hebrew letters is זכי. A Tanakh name: an Israelite (first in Ezra 2:9; 3 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “pure”. Adding up the numbers of its letters gives 37 — the same as the Torah word גדל, “to grow, be great”. That number points to Torah page 37 of 354 — in the portion Chayei Sarah. What that portion is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death. The verse that begins with the first letter of your name and ends with the last is Genesis 31:38. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Zaccai” — this exact spelling is what was calculated: זכי. 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 זכי gives 37.
37
The number 37 is the Torah word גדל — «to grow, be great» (Genesis 12:2).
And the man came into the house, and he ungirded the camels; and he gave straw and provender for the camels, and water to wash his feet and the feet of the men that were with him.
This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
The same number, 37, is given by these Tanakh names:
Abel הבל
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.
Final letters as 500–900 (mispar gadol) — 37. A Torah word with the same number is גדל — “to grow, be great” (Genesis 12:2).
Reduced, each letter to one digit (mispar katan) — 10. A Torah word with the same number is בדד — “alone” (Numbers 23:9).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 28. A Torah word with the same number is כח — “strength” (Genesis 4:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 158. A Torah word with the same number is ספיח — “aftergrowth” (Leviticus 25:5).
Squares of the letter values (mispar perati) — 549. A Torah word with the same number is ומגרש — “and pastureland” (Numbers 35:2).
Building: the sum grows with each letter (mispar bone’eh) — 71. A Torah word with the same number is מלא — “to fill” (Genesis 1:22).
The letters that come out are עלמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 140. A Torah word with the same number is מעל — “above” (Genesis 6:16).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 187. A Torah word with the same number is מספוא — “fodder” (Genesis 24:25).
The number 37 appears in the classical books 34 times across 18 works. The earliest mention is עולם אחד (~1480?).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 37. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. זכי has 3 letters: ז Zayin, כ Kaf, י Yod. The first letter is Zayin, the last is Yod.
For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name זכי does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For זכי these are ז and י. The Pentateuch has exactly one such verse — Genesis 31:38:
זה עשרים שנה אנכי עמך רחליך ועזיך לא שכלו ואילי צאנך לא אכלתי
This is from the portion Vayetzei. What it is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return.
The name זכי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 37 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
