The numero sign or numero symbol, №, (also represented as Nº, No, No./no.), is a typographic abbreviation of the word number(s) indicating ordinal numeration, especially in names and titles. For example, using the numero sign, the written long-form of the address "Number 22 Acacia Avenue" is shortened to "№ 22 Acacia Avenue", yet both forms are spoken long.
Typographically, the numero sign combines the uppercase Latin letter ⟨N⟩ with a usually superscript lowercase letter ⟨o⟩, sometimes underlined, resembling the masculine ordinal indicator, as a single ligature. The ligature has a code point in Unicode as precomposed character, U+2116 № NUMERO SIGN.
The Oxford English Dictionary derives the numero sign from Latin numero, the ablative form of numerus ("number", with the ablative denotations of "by the number, with the number"). In Romance languages, the numero sign is understood as an abbreviation of the word for "number", e.g. Italian numero, French numéro, and Portuguese and Spanish número.
The numero sign as a single glyph, despite its widespread usage internationally, is not a standard alphabetic symbol in virtually any European language. Its substitution by the two separate letters ⟨N⟩ and ⟨o⟩ is common.
In English, the non-ligature form is typical and is often used to abbreviate the word "number". (In North America, the number sign, , is more prevalent). The ligature form does not appear on British or American QWERTY keyboards
The numero symbol is not in common use in France and does not appear on a standard AZERTY keyboard. Instead, the French Imprimerie nationale recommends the use of the form "no" (an "n" followed by a superscript lowercase "o"). The plural form "nos" can also be used. In practice, the "o" is often replaced by the degree symbol (°), which is visually similar to the superscript "o" and is easily accessible on an AZERTY keyboard.
The numero sign is not typically used in Iberian Spanish, and it is not present on standard keyboard layouts. According to the Real Academia Española and the Fundéu BBVA, the word número (number) is abbreviated per the Spanish typographic convention of letras voladas ("flying letters"). The first letter(s) of the word to be abbreviated are followed by a period; then, the final letter(s) of the word are written as lowercase superscripts. This gives the abbreviations n.o (singular) and n.os (plural). The abbreviation "no." is not used, because it might be mistaken for the Spanish word no (no, not). Furthermore, nro. and núm. are also acceptable abbreviations for número. The numero sign either as a one-character symbol (№) or composed of the letter N plus the superscript "o" character (sometimes underlined or substituted by º) is common in Latin America, where the interpolated period is sometimes not used in abbreviations.

The medical prescriptions as an abbreviation for the Latin word numero to denote the number of prescribed dosages (for example, tablets or capsules), and on the price tags in drugstores and pharmacy websites to indicate number of unit doses in drug packages, although the standard abbreviation for use in prescriptions is (Cyrillic 'en').sign is sometimes used in Russia in
Indonesian and Malaysian
In some languages, Nr., nr., nr or NR is used instead, reflecting the abbreviation of the language's word for 'number'. German Nummer is represented this way, and this language capitalises all nouns and abbreviations of nouns. Lithuanian uses it as well, and it is usually capitalised in bureaucratic contexts, especially with the meaning 'reference number' (such as sutarties Nr., 'contract No.') but in other contexts it follows the usual sentence capitalisation (such as tel. nr., abbreviation for telefono numeris, 'telephone number'). It is most commonly lowercase in other languages, such as Dutch, Danish, Norwegian, Polish, Romanian, Estonian and Swedish. Some languages, such as Polish, omit the dot in abbreviations, if the last letter of the original word is present in the abbreviation.
Typing the symbol
On typewriters and computers that do not support this symbol, it is acceptable and commonplace to replace it with the trigraph "No." (letter "N", letter "o", and a period (full stop)).
On typewriters and computers that support the degree symbol or (preferably) masculine ordinal indicator, a digraph starting with "N", such as "N°" or "Nº", may suffice as a substitute for the numero sign, but only if it is to be presented exclusively within visual media, in a typeface and sizing that results in a passable approximation of the numero sign. Such digraphs are generally inappropriate for representing the numero sign in formal publications or in computer data.
On Russian computer keyboard layout, the № character is available and often located on the 3 key.
In Mac OS X, the character can be typed using "U.S. Extended" and "Irish Extended" keyboard layouts by typing ⇧ Shift+⌥ Option+;. As of macOS 10.13, this combination does not yield the numero symbol when "U.S." or "U.S. International" is chosen. It will only yield the numero symbol when "ABC – Extended" is chosen as the input keyboard.
U+2116 NUMERO SIGN is provided both for Cyrillic use, where it looks like [semi-cursive "N" followed by raised, underlined small "o"], and for compatibility with Asian standards, where it looks like [angular "N" followed by raised, underlined small "o", followed by a period]. ... Instead of using a special symbol, French practice is to use an "N" or an "n", according to context, followed by a superscript small letter "o" (No or no; plural Nos or nos). Legacy data encoded in ISO/IEC 8859-1 (Latin-1) or other 8-bit character sets may also have represented the numero sign by a sequence of "N" followed by the degree sign (U+00B0 degree sign). Implementations working with legacy data should be aware of such alternative representations for the numero sign when converting data.— The Unicode Standard.
