Character	Name	Code point	Alt code	HTML	LaTeX
	U+03B1. The Greek alphabet's first letter, small. Alt+224 on a number pad, from code page 437. It has no Option key on the U.S. layout. α in HTML, \alpha in LaTeX.
	U+0391. The capital. It tends to be drawn exactly like a Latin A, so it is rarely used as a symbol. No Alt code and no Option key. Α in HTML; LaTeX's kernel has no macro for it.
	U+03AC. Alpha with the accent of modern Greek, as in the letter's own name, άλφα.
	U+1D6FC. The slanted alpha of a printed formula. Unicode defines it as U+03B1 in an italic font. Added in Unicode 3.1.
	U+1D736. Bold and slanted: U+03B1 in a bold italic font, by Unicode's definition.
	Made of U+2220 and U+03B1. Alpha is a usual name for an angle.

How it works

The alpha symbol is α, Greek small letter alpha, U+03B1, the first letter of the Greek alphabet. The rows add the capital Α, accented alphas for Greek text, maths styles, and the look-alikes ɑ and ∝. On a Mac it has no Option key.

Read the full guide

α, ɑ and ∝ are three characters

α is the Greek letter. ɑ is a Latin letter, used in phonetic writing for an open back vowel. ∝ is the sign for is proportional to, and is sometimes mistaken for alpha. Each has its own code point, so a search for one will not find the others.

Why the capital is rare

Α, the capital, tends to be drawn exactly like a Latin A, so formulas use the small letter: for an angle, an angular acceleration, the fine-structure constant or a significance level. In astronomy α marks the brightest star of a constellation.

Greek text accents alpha in many ways. Unicode's Greek Extended block alone holds 46 ready-made alphas with breathing marks, accents and an iota.
In LaTeX, \alpha works in maths mode with no package. The kernel has no \Alpha, because the capital is an ordinary A.

Questions and answers

How do I type the alpha symbol on a Mac?

The U.S. layout has no Option key for α. Press Fn or the Globe key with E to open the Character Viewer and search for alpha. With the Greek keyboard layout switched on, the A key types α.

What is the Alt code for alpha?

With Num Lock on, hold Alt and type 224 on the number pad for the small α. The capital Α has no Alt code. In a web page write α or α, and Α for the capital.

What does the alpha symbol mean?

Alpha opens the Greek alphabet and stands for one as a Greek numeral. In science the small α names angles, alpha particles, angular acceleration and the significance level of a statistical test.

Is there an alpha emoji?

Not of the letter. One emoji has alpha among its search words, and it is 🦁 Lion. α itself is a letter and plain text, so it takes the size and color of the words round it.

How this list was compiled: Names, and the code points they belong to, are checked against UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), and printed in sentence case; notes that say Unicode defines it as quote its decomposition field. Notes that say Unicode's alias, Unicode's note or Unicode cross-references quote NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt), which is also where the English names of the Greek accents come from (psili, smooth breathing mark; dasia, rough breathing mark; varia; oxia; vrachy; iota subscript). The version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt). The Alt code, HTML entities and LaTeX macros come from this family's lookup of typing methods, built from the HTML standard's entity list, the LaTeX sources and the code page tables. That alpha opens the Greek alphabet with the value one as a numeral, was derived from a Phoenician letter, gave rise to the Latin and Cyrillic letters A, names angles, is rarely used as a capital symbol because it looks like a Latin A, and is sometimes confused with the proportional-to sign, and what the Latin alpha stands for in the International Phonetic Alphabet, is from https://en.wikipedia.org/wiki/Alpha (wikitext read 2026-09-30).
