Number Symbols

Digits in every form Unicode gives them: raised ¹ ² ³ for footnotes, lowered ₁ ₂ ₃ for chemical formulas, circled ① for lists, plus Roman Ⅳ and fractions. These are single characters rather than formatting, so they hold their shape in a username, a spreadsheet cell or a plain-text field.

Copy and Paste Number Symbols

These are digits that already carry their formatting inside the character. A raised ¹, a lowered ₂, a circled ① or a Roman Ⅳ is one character, not a digit with a style applied to it — which is why it survives being pasted into a username, a spreadsheet cell, a tweet or any other place that strips real formatting.

What Are Number Symbols?

Number symbols are Unicode characters that represent a number without being an ordinary digit. Some are positional digits drawn differently — ² is Superscript Two, ２ is Fullwidth Digit Two, 𝟐 is Mathematical Bold Digit Two. Others encode a whole number in one character: ⑳ is Circled Number Twenty, Ⅻ is Roman Numeral Twelve, ⅜ is Vulgar Fraction Three Eighths.

The distinction that matters in practice is between a character and a format. If you make a 2 superscript in a word processor, you have applied a style, and the style is the first thing lost when the text is copied somewhere plain. ² is a different character from 2, so nothing can strip it.

How to Use Number Symbols

Small Number Symbols for Footnotes and Formulas

The superscript digits ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ give you all ten, so any footnote marker can be built by placing them side by side — ¹² reads as twelve. The subscript set ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ does the same below the line, which is what a chemical formula needs: H₂O, CO₂, C₆H₁₂O₆.

One warning worth having before you use them. ¹, ² and ³ are much older characters than the rest — they were in the 8-bit Latin-1 set decades before Unicode added ⁰ and ⁴ through ⁹. Many fonts therefore draw the first three at a slightly different size or height from the other seven, so a number like ¹⁴ can look uneven. If that matters, check it in the font you are actually publishing in.

Typing Number Symbols on a Keyboard

Six characters on this page have a Windows Alt code, and they are all fractions and low superscripts: hold Alt and type 0185 for ¹, 0178 for ², 0179 for ³, 0188 for ¼, 0189 for ½, 0190 for ¾. The leading zero matters — it selects the Windows character set rather than the older DOS one.

Everything else needs the full Unicode value, because these characters were added long after the Alt-code tables were fixed. There is no keyboard route at all to ⁴, ₂, ① or Ⅳ on a phone. On a Mac the Character Viewer opens with Ctrl+Cmd+Space; on Linux it is Ctrl+Shift+U followed by the hex value. For everything else, taking the character from the grid is quicker than any of these.

Number Symbols in Lists

Circled and bracketed digits are useful precisely where automatic numbering is unavailable — a social bio, a chat message, a plain-text README, an image caption. ① ② ③ keep an ordered list readable when the platform would otherwise flatten your numbering, and ⑴ ⑵ ⑶ or ⒈ ⒉ ⒊ do the same in a more formal register.

Types of Number Symbols

Superscript and Subscript Number Symbols

⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ above the line and ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ below it. Both sets are complete, which is not true of the superscript letters — Unicode never finished those, so you can write any number small but not any word.

Circled Number Symbols

Four different circled series sit here and they are genuinely different characters, not one design at four weights. ① ② ③ run to ⑳ and start at ⓪; the filled ❶ ❷ ❸ run to ⓴ with ⓿ for zero; ➀ ➁ ➂ and ➊ ➋ ➌ are the Dingbats versions, drawn in a sans-serif face and stopping at ten; ⓵ ⓶ ⓷ are double-circled. Mixing series in one list is the usual way these look wrong.

Bracketed and Full Stop Number Symbols

⑴ ⑵ ⑶ run to ⒇ and ⒈ ⒉ ⒊ to ⒛. The full-stop forms are single characters that include the period, so they align in a way a hand-typed "1." does not when the list runs into double digits.

Roman Numeral Number Symbols

Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ through Ⅻ, with lowercase ⅰ ⅱ ⅲ through ⅻ. These exist as characters mainly for East Asian typesetting, where a Roman numeral has to occupy one cell. Typing I, V and X gives the same reading in most contexts, so the single characters matter when alignment does.

Fraction Number Symbols

½ ⅓ ⅔ ¼ ¾ ⅕ ⅖ ⅗ ⅘ and the rest, down to sevenths, ninths and tenths — ⅐ ⅑ ⅒ — plus ↉ for zero thirds and ⅟, a numerator one for building fractions that have no character of their own.

Styled Digit Number Symbols

𝟎 𝟏 𝟐 are mathematical bold, 𝟘 𝟙 𝟚 double-struck, 𝟶 𝟷 𝟸 monospace, and ０ １ ２ fullwidth. All four sets are ordinary digits redrawn, and they are the ones most likely to be missing from an older font.

Best Uses for Number Symbols

Number Symbols in Documents and Citations

A superscript character is the safest way to mark a reference in text that will be copied around — a wiki, a code comment, a chat message. № is the numero sign, the abbreviation for "number" used across Europe and Russia where English writes "No." or "#", and it is a single character rather than two.

Number Symbols in Names and Profiles

Display names are where the circled and fullwidth forms turn up most, because they read as numbers while looking deliberate. The fullwidth digits ０ １ ２ space themselves out to a full character cell, which is why a year written in them looks airy rather than cramped.

Number Symbols Unicode Names and Codes

The formal names are literal about what each character is: ¹ is U+00B9 Superscript One, ₁ is U+2081 Subscript One, ① is U+2460 Circled Digit One, ➊ is U+278A Dingbat Negative Circled Sans-Serif Digit One, ⓵ is U+24F5 Double Circled Digit One, Ⅰ is U+2160 Roman Numeral One. Each tile shows its own code point.

The blocks are worth knowing if you are picking a set to use throughout a document. Superscripts and subscripts live from U+2070 to U+209C, enclosed alphanumerics from U+2460, Dingbats from U+2780, and the styled digits far above at U+1D7CE. Characters from a single block are drawn by the same font and will match each other; characters from different blocks may not.

Frequently Asked Questions About Number Symbols

How do I make small numbers to copy and paste?

Take them from the grid — the superscript row ¹ ² ³ ⁴ for raised digits and the subscript row ₁ ₂ ₃ ₄ for lowered ones. They are characters, not formatting, so they stay small wherever you put them, including places that have no formatting at all.

How do I type a number symbol without copying it?

On Windows only six of them have a short code: Alt+0185 ¹, Alt+0178 ², Alt+0179 ³, Alt+0188 ¼, Alt+0189 ½, Alt+0190 ¾. The rest need the full Unicode value, and on a phone there is no keyboard route at all.

Does # mean number?

In American usage yes — #4 reads as "number 4" — though the same character means "sharp" in music and a hashtag online. The dedicated character for the job is №, the numero sign, standard in Russian, French and much of Europe.

Why do circled numbers stop at twenty?

Because that is where Unicode stopped for the plain and filled series. ⑳ and ⓴ are the last ones; past twenty there is no character, so a longer list needs ordinary digits.

Are subscript digits enough for chemistry?

For formulas, yes — all ten digits exist, so H₂O and C₆H₁₂O₆ are written entirely in real characters. What Unicode does not give you is a complete set of subscript letters, so a notation that needs a lowered letter will not survive as plain text.

Why does a number symbol show as a box on someone else's screen?

Their font has no glyph for it. The superscripts, fractions and circled digits are old and widely supported. The styled sets 𝟏 𝟙 𝟷 are the most recent and the most likely to be missing, so avoid them where you cannot control the font.

Related Collections for Number Symbols

For the operators that go around these digits — plus, minus, square root, pi — see math symbols. The circled digits share a shape with the circle symbols, and the bracketed ones with bracket symbols. If you want a whole line of text restyled rather than one character at a time, the font generator does that instead. Everything else is indexed at symbol collections.
