Editing Numero sign (section)

==Usages==
The numero sign's non-ligature substitution by the two separate letters {{angbr|N}} and {{angbr|o}} is common. A capital or lower-case "n" may be used, followed by "o.", superscript "o", ordinal indicator, or the degree sign; this will be understood in most languages.

===Bulgarian===
[[File:Bulgarian BDS layout.svg|thumb|upright=1.5|[[Bulgarian language|Bulgarian]] keyboard layout (BDS 5237:1978)]]
In Bulgarian the numero sign is often used and it is present in three widely used keyboard layouts accessible with {{keypress|Shift-0}} in BDS and prBDS and with {{keypress|Shift-3}} on the Phonetic layout.

===English===
In many forms of English, the non-ligature form {{char|No.}} is typical and is often used to abbreviate the word "number".<ref name=Concise /> In North America, the [[number sign]], {{char|#}}, is more prevalent. The ligature form does not appear on [[British and American keyboards|British or American QWERTY keyboards]].

===French===
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 "n<sup>o</sup>" (an "n" followed by a [[superscript]] lowercase "o"). The plural form "n<sup>os</sup>" can also be used.<ref name=imp_nat>{{cite book|title=Lexique des règles typographiques en usage à l'Imprimerie nationale|publisher=[[Imprimerie nationale]]|year=2002|isbn=978-2-7433-0482-9|language=fr}}</ref> 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.

===Indonesian and Malaysian===
"Nomor" in Indonesian and "nombor" in Malaysian; therefore "No." is commonly used as an abbreviation with standard spelling and full stop.

===Italian===

The sign is usually replaced with the abbreviations "n." or "nº", the latter using a [[masculine ordinal indicator]], rather than a superscript "O".<ref>{{cite web|url=http://www.chass.utoronto.ca/~ngargano/corsi/corrisp/abbreviazioni.html|title=La corrispondenza italiana: abbreviazioni|access-date=17 May 2010|archive-date=14 June 2010|archive-url=https://web.archive.org/web/20100614090655/http://www.chass.utoronto.ca/~ngargano/corsi/corrisp/abbreviazioni.html|url-status=dead}}</ref>

===Philippine languages===
Because of more than three centuries of [[History of the Philippines (1521–1898)|Spanish colonisation]], the word ''número'' is found in almost all Philippine languages. "No." is its common notation in local languages as well as English.

===Portuguese===
In Portugal, the similar-looking notation {{char|n.º}} is often used.<ref>For example, {{cite web|title=Lei da Nacionalidade (Consolidado)|work=Diário da República Eletrónico |url=https://dre.pt/web/guest/legislacao-consolidada/-/lc/34536975/diploma|language=pt|trans-title=Law of Nationality (consolidated)|publisher=Diário da República}} Portuguese official legislation Web site, with frequent use of "n.º".</ref> In Brazil, where Portuguese is the official language, {{char|nº}} is often used on official documents.<ref>For example, [http://www.planalto.gov.br/ccivil_03/_ato2015-2018/2017/decreto/D9199.htm Decree no. 9.199, of 20 November 2017], Government of Brazil {{in lang|pt}}. Brazilian presidency Web site, with frequent use of "nº".</ref> In both cases, the symbol used ({{char|º}}) is the [[masculine ordinal indicator]]. However, the [[Brazilian National Standards Organization]] (ABNT) determines that the word "número" should be abbreviated "n." only.

===Russian===
[[File:KB Russian.svg|thumb|Russian [[keyboard layout]] for [[Microsoft Windows|Windows]]. The {{char|№}} sign can be seen on the {{keypress|3}} key.]]
Although the letter {{angbr|[[N]]}} is not in the [[Russian alphabet|Cyrillic alphabet]], the numero sign {{char|№}} is typeset in Russian publishing, and is available on [[Russian alphabet#Keyboard layout|Russian computer and typewriter keyboards]].

The numero sign is very widely used in Russia and other [[post-Soviet states]] in many official and casual contexts. Examples include usage for law and other official documents numbering, names of institutions (hospitals, kindergartens, schools, libraries, organization departments and so on), numbering of periodical publications (such as newspapers and magazines), numbering of public transport routes, etc.

{{not a typo|"№ п/п"}} (''{{lang|ru|номер по порядку}}'', "sequential number") is universally used as a table header to denote a column containing the table row number.

The {{char|№}} sign is sometimes used in Russian [[medical prescription]]s (which according to the law must be written in [[Latin language]]<ref>[http://pravo.gov.ru/proxy/ips/?docbody=&nd=102554270 Order of the Ministry of Health of Russian Federation No. 4N], chapter I, article 17.</ref>) as an abbreviation for the Latin word ''numero'' to indicate 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 dose]]s in drug packages, although the standard abbreviation for use in prescriptions is the Latin {{char|N.}}

===Spanish===
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]]<ref>{{cite web | title=¿Cuál es la abreviatura de "número"? | publisher=Real Academia Española| url=https://www.rae.es/duda-linguistica/cual-es-la-abreviatura-de-numero | language=es | access-date=21 January 2024}}</ref> and the [[Fundéu BBVA]],<ref>{{cite web|title=número, abreviatura|url=http://www.fundeu.es/consulta/numero-abreviatura-145/|website=Fundéu BBVA|date=23 February 2006|access-date=21 March 2016}}</ref> the word ''número'' (number) is abbreviated per the Spanish typographic convention of [[Superior letter#Use in Spanish|''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.<sup>o</sup> (singular) and n.<sup>os</sup> (plural). The abbreviation "no." is not used (it might be mistaken for the Spanish negative word ''no''). The abbreviations  nro. and núm. are also acceptable. The numero sign, either as a one-character symbol {{char|№}} or composed of the letter N plus superscript "o" (sometimes underlined or substituted by the [[ordinal indicator]], {{char|º}}), is common in Latin America, where the interpolated period is sometimes not used in abbreviations.

===Nr.===
In some languages, ''Nr.'', ''nr.'', ''nr'' or ''NR'' is used instead, reflecting the abbreviation of the language's word for "number". In German, which capitalises all nouns and abbreviations of nouns, the word ''{{lang|de|Nummer}}'' is abbreviated as ''Nr.'' Lithuanian uses this spelling as well, and it is usually capitalised in [[Bureaucracy|bureaucratic]] contexts, especially with the meaning "reference number" (such as ''{{lang|lt|sutarties Nr.}}'', "contract No.") but in other contexts it follows the usual sentence capitalisation (such as ''tel. nr.'', abbreviation for ''{{lang|lt|telefono numeris}}'', "telephone number").  It is commonly lowercase in other languages, such as Dutch, Danish, Norwegian, Polish, Romanian, Estonian and Swedish. Some languages, such as Polish, omit the dot in [[abbreviation]]s if the abbreviation ends with the last letter of the original word.
