The name Shammah in Hebrew letters is שמה. 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.
שמה
In short
Your name in Hebrew letters is שמה. A Tanakh name: an Edomite and four Israelites (first in Genesis 36:13; 7 mentions in the Tanakh). Adding up the numbers of its letters gives 345 — the same as the Torah word משה, “Moses”. That number points to Torah page 345 of 354 — in the portion Nitzavim. What that portion is about: “You are standing”: the covenant with all, and with those not here; “the word is very near to you”; choose life. The verse that begins with the first letter of your name and ends with the last is Genesis 49:31. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Shammah” — this exact spelling is what was calculated: שמה. 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 שמה gives 345.
345
The number 345 is the Torah word משה — «Moses» (Exodus 2:10).
and ye have seen their detestable things, and their idols, wood and stone, silver and gold, which were with them--
This is from the portion Nitzavim. What it is about: “You are standing”: the covenant with all, and with those not here; “the word is very near to you”; choose life.
The same number, 345, is given by these Tanakh names:
Moses משה
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) — 345. A Torah word with the same number is משה — “Moses” (Exodus 2:10).
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) — 39. A Torah word with the same number is גאלה — “redemption” (Leviticus 25:24).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1255.
Squares of the letter values (mispar perati) — 91625.
Building: the sum grows with each letter (mispar bone’eh) — 985.
The letters that come out are ביצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 102. A Torah word with the same number is בעל — “master, owner” (Genesis 14:13).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 446.
The number 345 appears in the classical books 127 times across 45 works. The earliest mention is ילקוט שמעוני (~1260).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 345. 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. שמה has 3 letters: ש Shin, מ Mem, ה He. The first letter is Shin, the last is He.
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 שמה appears in the Torah as a word 82 times. The first time is Genesis 11:9.
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 שמה these are ש and ה. The Pentateuch has 15 such verses. The first of them is Genesis 49:31:
שמה קברו את אברהם ואת שרה אשתו שמה קברו את יצחק ואת רבקה אשתו ושמה קברתי את לאה
This is from the portion Vayechi. What it is about: Jacob blesses Ephraim and Manasseh and all his sons; Jacob's death and burial in Hebron; Joseph's death.
The name שמה has no such day. The numbers of the dates in a year cover 326 values out of 940, and 345 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.
