The name Rei in Hebrew letters is רעי. 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.
רעי
In short
Your name in Hebrew letters is רעי. A Tanakh name: an Israelite (first in 1 Kings 1:8; 1 mention in the Tanakh). Meaning, per Strong’s dictionary (1890): “social”. Adding up the numbers of its letters gives 280 — the same as the Torah word עיר, “city”. That number points to Torah page 280 of 354 — in the portion Matot. What that portion is about: Vows and their annulment; the war with Midian; the tribes of Reuben and Gad ask for land beyond the Jordan. The verse that begins with the first letter of your name and ends with the last is Exodus 16:29. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Rei” — this exact spelling is what was calculated: רעי. 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 רעי gives 280.
280
The number 280 is the Torah word עיר — «city» (Genesis 4:17).
But all the women children, that have not known man by lying with him, keep alive for yourselves.

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) — 280. A Torah word with the same number is עיר — “city” (Genesis 4:17).
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) — 46. A Torah word with the same number is מאה — “hundred” (Genesis 5:3).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1175.
Squares of the letter values (mispar perati) — 45000.
Building: the sum grows with each letter (mispar bone’eh) — 750. A Torah word with the same number is נתש — “to uproot” (Deuteronomy 29:27).
The letters that come out are גזמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 50. A Torah word with the same number is כל — “all, every” (Genesis 1:21).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 660. A Torah word with the same number is מצנפת — “turban” (Exodus 28:4).
The number 280 appears in the classical books 57 times across 26 works. The earliest mention is ספר קרניים (~1400).

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 רעי these are ר and י. The Pentateuch has 2 such verses. The first of them is Exodus 16:29:
ראו כי ה׳ נתן לכם השבת על כן הוא נתן לכם ביום הששי לחם יומים שבו איש תחתיו אל יצא איש ממקמו ביום השביעי
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
The name רעי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 280 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.
