=== Other uses ===
* [[Algebraic notation (chess)|Algebraic notation for chess]]: A hash after a move denotes [[checkmate]].
* [[American Sign Language]] transcription: The hash prefixing an all-caps word identifies a lexicalized fingerspelled sign, having some sort of blends or letter drops. All-caps words without the prefix are used for standard English words that are fingerspelled in their entirety.<ref>{{cite web |last1=Vicars |first1=Bill |title=Lexicalization |url=http://www.lifeprint.com/asl101/topics/lexicalized_fingerspelling.htm |publisher=ASL University |access-date=6 September 2015 |archive-date=10 September 2015 |archive-url=https://web.archive.org/web/20150910183425/http://www.lifeprint.com/asl101/topics/lexicalized_fingerspelling.htm |url-status=live }}</ref>

* [[Note (typography)|Footnote]] symbols (or endnote symbols): Due to ready availability in many fonts and directly on computer keyboards, "#" and other symbols (such as the [[caret]]) have in recent years begun to be occasionally used in catalogues and reports in place of more traditional symbols (esp. [[Dagger (mark)|dagger, double-dagger]], [[pilcrow]]).
* Linguistic [[phonology]]: {{char|#}} denotes a word boundary. For instance, {{code|/d/ → [t] / _#}} means that {{char|/d/}} becomes {{char|[t]}} when it is the last segment in a word (i.e. when it appears before a word boundary).
* Linguistic [[syntax]]: A hash before an example sentence denotes that the sentence is semantically ill-formed, though grammatically well-formed. For instance, "#The toothbrush is pregnant" is a grammatically correct sentence, but the meaning is odd.<ref>{{cite book|last=Carnie|first=Andrew|year=2006|title=Syntax: A Generative Introduction|location=Oxford|publisher=Wiley-Blackwell|isbn=1-4051-3384-8|edition=2nd|url-access=registration|url=https://archive.org/details/syntaxgenerative0000carn}}</ref><ref>{{Cite book | first=R.

In radiotherapy, a full dose of radiation is divided into smaller doses or 'fractions'. These are given the shorthand {{char|#}} to denote either the number of treatments in a prescription (e.g. 60Gy in 30#), or the fraction number (#9 of 25).
