The name Ater in Hebrew letters is אטר. 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.
אטר
In short
Your name in Hebrew letters is אטר. A Tanakh name: the name of three Israelites (first in Ezra 2:16; 5 mentions in the Tanakh). Adding up the numbers of its letters gives 210 — the same as the Torah word דור, “generation”. That number points to Torah page 210 of 354 — in the portion Behar. What that portion is about: “On the mountain”: the sabbatical year and the jubilee; the land is not sold forever; redemption of land and servants; the ban on interest. The verse that begins with the first letter of your name and ends with the last is Genesis 23:15. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Ater” — this exact spelling is what was calculated: אטר. 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 אטר gives 210.
210
The number 210 is the Torah word דור — «generation» (Genesis 6:9).
And thou shalt number seven sabbaths of years unto thee, seven times seven years; and there shall be unto thee the days of seven sabbaths of years, even forty and nine years.
This is from the portion Behar. What it is about: “On the mountain”: the sabbatical year and the jubilee; the land is not sold forever; redemption of land and servants; the ban on interest.
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) — 210. A Torah word with the same number is דור — “generation” (Genesis 6:9).
Reduced, each letter to one digit (mispar katan) — 12. A Torah word with the same number is הוא — “he, it” (Genesis 2:11).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 30. A Torah word with the same number is כי — “for, because, that” (Genesis 1:4).
Cumulative: a letter plus all letters before it (mispar kidmi) — 841. A Torah word with the same number is הנפשות — “the persons” (Leviticus 18:29).
Squares of the letter values (mispar perati) — 40082.
Building: the sum grows with each letter (mispar bone’eh) — 221. A Torah word with the same number is ארך — “length” (Genesis 6:15).
The letters that come out are תנג — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 453. A Torah word with the same number is מחתה — “firepan” (Exodus 25:38).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1040.
The number 210 appears in the classical books 29 times across 21 works. The earliest mention is בעל הטורים על התורה (~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 — 210. 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 אטר 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 אטר these are א and ר. The Pentateuch has 15 such verses. The first of them is Genesis 23:15:
אדני שמעני ארץ ארבע מאת שקל כסף ביני ובינך מה הוא ואת מתך קבר
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.
«And thou shalt number seven sabbaths of years unto thee, seven times seven years; and there shall be unto thee the days of seven sabbaths of years, even forty and nine years.»
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.
