Avoid using the [[Number sign|{{!xt|#}}]] symbol (known as the [[number sign]], hash sign, pound sign, or octothorpe) when referring to numbers or rankings. Instead write {{xt|number}}, {{xt|No.}} or {{xt|Nos.}}; do not use the symbol [[Numero sign|{{!xt|№}}]]. For example:
{| role="presentation" style="margin:0.2em 0 0.5em 1.6em; background:transparent;color: var( --color-base );"
|-
| style="padding-right:1em" | {{em|Incorrect:}}
| {{!xt|Her album reached #1 in the UK albums chart.}}
|-
| style="padding-right:1em" | {{em|Correct:}}
| {{xt|Her album reached number one in the UK albums chart.}}
|-
| style="padding-right:1em" | {{em|Correct:}}
| {{xt|Her album reached {{Abbr|No.|Number}} 1 in the UK albums chart.}}
|-
| style="padding-right:1em" | {{em|Correct:}}
| {{xt|Her albums ''Foo'' and ''Bar'' reached {{abbr|Nos.|Numbers}} 1 and 3.}}
|-
| style="padding-right:1em" | {{em|Correct:}}
| {{xt|Her albums ''Foo'' and ''Bar'' reached numbers one and three in the UK albums chart.}}
|}

An exception is issue numbers of comic books, which unlike for other periodicals are conventionally given in general text in the form {{xt|#1}}, unless a volume is also given, in which case write {{xt|volume two, number seven}} or {{xt|{{Abbr|Vol.|Volume}} 2, {{Abbr|No.|Number}} 7}}. Another exception are periodical publications carrying both, issue ''and'' number designations (typically one being a year-relative and the other an absolute value); they should be given in the form {{xt|2 #143}} in citations, or be spelt out as
{{xt|{{Abbr|Iss.|Issue}} 2, {{Abbr|No.|Number}} 143}} in text. When using the [[Wikipedia:Manual of Style/Abbreviations|abbreviations]], write {{xt|<code><nowiki>{{abbr|Vol.|Volume}}</nowiki></code>}}, {{xt|<code><nowiki>{{abbr|Iss.|Issue}}</nowiki></code>}}, {{xt|<code><nowiki>{{abbr|No.|Number}}</nowiki></code>}}, or {{xt|<code><nowiki>{{abbr|Nos.|Numbers}}</nowiki></code>}}, at first occurrence.
