The name Umar in Hebrew letters is עומר. 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.
עומר
In short
Your name in Hebrew letters is עומר. “Sheaf.” The measure of barley brought the day after Passover; from it the forty-nine days to Shavuot are counted (Leviticus 23:15). Adding up the numbers of its letters gives 316 — the same as the Torah word סנור, “blindness”. That number points to Torah page 316 of 354 — in the portion Re'eh. What that portion is about: “See”: blessing and curse; one place of worship; the tithe; permitted food; the three pilgrimage festivals. The verse that begins with the first letter of your name and ends with the last is Genesis 6:14. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Umar” — this exact spelling is what was calculated: עומר. 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 עומר gives 316.
316
The number 316 is the Torah word סנור — «blindness» (Genesis 19:11).
then it shall come to pass that the place which HaShem your G-d shall choose to cause His name to dwell there, thither shall ye bring all that I command you: your burnt-offerings, and your sacrifices, your tithes, and the offering of your hand, and all your choice vows which ye vow unto HaShem.
This is from the portion Re'eh. What it is about: “See”: blessing and curse; one place of worship; the tithe; permitted food; the three pilgrimage festivals.
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) — 316. A Torah word with the same number is סנור — “blindness” (Genesis 19:11).
Reduced, each letter to one digit (mispar katan) — 19. A Torah word with the same number is גוי — “nation” (Genesis 10:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 55. A Torah word with the same number is הלך — “to go, walk” (Genesis 2:14).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1286.
Squares of the letter values (mispar perati) — 46536.
Building: the sum grows with each letter (mispar bone’eh) — 578. A Torah word with the same number is בעשור — “on the tenth” (Leviticus 16:29).
The letters that come out are זפיג — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 100. A Torah word with the same number is על — “on, over” (Genesis 1:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 732. A Torah word with the same number is לשבת — “to dwell” (Genesis 13:6).
The number 316 appears in the classical books 7 times across 5 works. The earliest mention is כל בו (~1300).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 316. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

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 עומר 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 עומר these are ע and ר. The Pentateuch has 2 such verses. The first of them is Genesis 6:14:
עשה לך תבת עצי גפר קנים תעשה את התבה וכפרת אתה מבית ומחוץ בכפר
This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.
«then it shall come to pass that the place which HaShem your G-d shall choose to cause His name to dwell there, thither shall ye bring all that I command you: your burnt-offerings, and your sacrifices, your tithes, and the offering of your hand, and all your choice vows which ye vow unto HaShem.»
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.
