.rs is the Internet country code top-level domain (ccTLD) for Serbia.[a] The domain name registry that operates it is the Serbian National Internet Domain Registry (RNIDS). The letters rs stand for Republika Srbija/Република Србија (Republic of Serbia).
It is intended to be used with few restrictions, and it is widely used in Serbia. Because of English words ending with the letters "rs", this domain is also used in the construction of domain hacks, and projects written in Rust.
The former Serbia and Montenegro used the .yu domain when still called the Federal Republic of Yugoslavia. In June 2006 Serbia and Montenegro split into two separate countries. On 8 July 2006 the Serbian Ministry of Science and a group of 34 interested organizations founded the National Internet Domain Registry - RNIDS. On 26 September 2006, the ISO 3166 Maintenance Agency decided to allocate RS as the ISO 3166-1 alpha-2 code for Serbia. IANA assigned .rs as the ccTLD for this country.
In 2007 ICANN also resolved that RNIDS, the operators of the new .rs domain registry, should temporarily operate the former .yu domain until its eventual abolition on or before 30 September 2009. This allowed a two-year transition period for existing .yu names to transferred either to .rs for Serbia or to .me for Montenegro. The .yu domain finally expired on 30 March 2010.
By 2018, it became convention for sites related to the Rust programming language to use .rs domain names. Prominent examples include docs.rs, the standard location for Rust's user-built package documentation, and diesel.rs, "a Safe, Extensible ORM and Query Builder for Rust". 
On December 10, 2018, .RS TLD started offering full Serbian Latin letters domain registration (together with other letters used by official minorities groups in Serbia) from December 10th, 2018. - totalling 67 letters which can be used for a domain name.
