The name Shemaiah in Hebrew letters is שמעיה. 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.
שמעיה
In short
Your name in Hebrew letters is שמעיה. A Tanakh name: the name of twenty-five Israelites (first in 1 Kings 12:22; 41 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “God has heard”. Adding up the numbers of its letters gives 425 — the same as the Torah word תכה, “to sit at the feet”. That number points to Torah page 71 of 354 — in the portion Miketz. What that portion is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack. 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 “Shemaiah” — this exact spelling is what was calculated: שמעיה. 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 שמעיה gives 425.
425
The number 425 is the Torah word תכה — «to sit at the feet» (Deuteronomy 33:3).
And he slept and dreamed a second time: and, behold, seven ears of corn came up upon one stalk, rank and good.
This is from the portion Miketz. What it is about: Pharaoh's dreams of seven cows and seven ears; Joseph rules Egypt; the brothers come for grain; the cup in Benjamin's sack.
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) — 425. A Torah word with the same number is תכה — “to sit at the feet” (Deuteronomy 33:3).
Reduced, each letter to one digit (mispar katan) — 20. A Torah word with the same number is היה — “to be, become” (Genesis 1:2).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 65. A Torah word with the same number is אדני — “my Lord” (Genesis 15:2).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1635.
Squares of the letter values (mispar perati) — 96625.
Building: the sum grows with each letter (mispar bone’eh) — 1895.
The letters that come out are ביזמצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 149. A Torah word with the same number is קדמה — “east of” (Genesis 2:14).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 596. A Torah word with the same number is שמרון — “Shimron, son of Issachar” (Genesis 46:13).
The number 425 appears in the classical books 3 times across 3 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 — 425. 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. שמעיה has 5 letters: ש Shin, מ Mem, ע Ayin, י Yod, 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 שמעיה 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 שמעיה 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.
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.
