The characters N/A (sometimes n/a) are an abbreviation that is mainly used in information tables. It stands for one of the following:
- Not available: Where there exists a lack of data. It also means a temporary unavailability of that piece of data (although TBA or TBD is often used instead). For example, in a price table, when new articles have arrived but the price is not yet available, it is usually expressed with n/a. In Microsoft Excel, the function NA() or special entry #N/A may be used.
- Not applicable: Where three or more elements are not compatible, it is said the resulting data is not applicable. For example, in a sport results table, where all teams are columns and rows, those cells which would show a team versus itself are usually marked with a symbol or with N/A.
- No answer: Refers to something that has no known or available answer.
- Not announced: As in the title isn't announced yet.
- Naturally aspirated: An internal combustion engine devoid of forced induction methods.
- Not assessed: Refers to the topic not being assessed.
