Number sign is a name for the symbol #, which is used for a variety of purposes including, in some countries, the designation of a number (for example, "#1" stands for "number one"). The symbol is defined in Unicode as U+0023 # number sign (HTML: #); it is also present in ASCII with the same value.
In Commonwealth English, the symbol is usually called the hash and the corresponding telephone key is called the hash key. In American English, the symbol is usually called the pound sign (outside the US, this term often describes instead the British currency symbol "£") and the telephone key is called the pound key.[1] In Canadian English, this key is most frequently called the pound key but also in some circumstances the number sign key.
In many parts of the world, including most of the Commonwealth (including the UK, Australia and French Canada), Russia, and most of Europe, number sign (or equivalents in local languages) instead refers to the numero sign ("№").
The symbol is easily confused with the musical symbol called sharp (♯). In both symbols, there are two pairs of parallel lines. The key difference is that the number sign has true horizontal strokes while the sharp sign has two slanted parallel lines which must rise from left to right, in order to avoid being confused with the musical staff lines. Both signs may have true vertical lines; however, they are compulsory in the sharp sign, but optional in the number sign (#) depending on typeface or handwriting style. Thus, only the number sign may have an italic appearance.
Other names in English
The symbol has many other names (and uses) in English.
Comment sign
Taken from its use in many shell scripts and some programming languages (such as Perl) to start comments.
Cross
In China, non-native English speakers often refer to the number sign as "cross". It is said as jĭng in Chinese, as it looks like the Chinese character for water well ("井").
Hex
Common usage in Singapore and Malaysia, as spoken by many recorded telephone directory-assistance menus: 'Please enter your phone number followed by the hex key'. The term 'hex' is discouraged in Singapore in favour of 'hash'.[clarification needed]
Octothorp, octothorpe, octathorp, octatherp
Used by Bell Labs engineers by 1968.[2] Lauren Asplund says that he and a colleague were the source of octothorp at AT&T engineering in New York in 1964. The Merriam-Webster New Book of Word Histories, 1991, has a long article that is consistent with Doug Kerr's essay,[3] in that it says "octotherp" was the original spelling, and that the word arose in the 1960s among telephone engineers as a joke. The first appearance of "octothorp" in a US patent is in a 1973 filing which also refers to the six-pointed asterisk (✻) used on telephone buttons as a "sextile".[4]
Sharp
Resemblance to the glyph used in music notation, U+266F (♯). So called in the name of the Microsoft programming languages C# and F#. However Microsoft says "It's not the 'hash' (or pound) symbol as most people believe. It's actually supposed to be the musical sharp symbol. However, because the sharp symbol is not present on the standard keyboard, it's easier to type the hash ('#') symbol. The name of the language is, of course, pronounced 'see sharp'."[5] According to the ECMA-334 C# Language Specification, section 6, Acronyms and abbreviations, the name of the language is written "C#" ("LATIN CAPITAL LETTER C (U+0043) followed by the NUMBER SIGN # (U+0023)") and pronounced "C Sharp".[6]
Space
Used by editors to denote where space should be inserted in a galley proof. This can mean
a line space (the space between two adjacent lines denoted by line # in the margin),
a hair space (the space between two letters in a word, denoted by hr #)
a word space, or letter space (the space between two words on a line, two letter spaces being ##)
Em- and en-spaces (being the length of a letter m and n, respectively) are denoted by a square-shaped em- or en-quad character (⊞ and ⊟, respectively).[citation needed]
Square
Occasionally used in the UK (e.g. sometimes in BT publications and automatic messages) – especially during the Prestel era, when the symbol was a page address delimiter. The International Telecommunications Union specification ITU-T E.161 3.2.2 states: "The # is to be known as a 'square' or the most commonly used equivalent term in other languages."
Others
crosshatch, (garden) fence, mesh, flash, grid, pig-pen, tictactoe, scratch (mark), (garden) gate, hak, oof, rake, sink, corridor, crunch, punch mark.[7]
