United Nations documents have a symbol, which serves as a unique identifier. Each symbol is composed of letters and numbers, which indicates the organ to which the document is being submitted or the organ that is issuing the document. For example, all documents of the Security Council start with S/:
- The basic format for the symbols of Security Council documents is: S/[year]/[sequential number], e. g., S/1998/318. From 1946 to 1993, the format was S/[sequential number], e. g., S/24111.
- Resolutions of the Security Council have a symbol the following format: S/RES/[sequential number] ([year]).
- The format of the symbol for the Presidential Statements is: S/PRST/[year]/[sequential number].
All language versions of a document carry the same symbol.
