.rs

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. In July 2006 the Serbian Ministry of Science and a group of 34 interested organizations founded the National Internet Domain Registry (RNIDS). In 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.

The delegation of name servers by IANA started in September 2007.^[3] Registration of the .rs domain names commenced on 10 March 2008.^{[citation needed]}

In 2007 ICANN also resolved^[4] 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.^[5]

In 2018, a Brazilian company began marketing .rs domain names towards entities based in Rio Grande do Sul, which shares the RS two-letter code within Brazil, as well as the BR-RS ISO 3166 code.^[6]

In 2018, .RS TLD started offering full Serbian Latin letters domain registration (together with other letters used by official minorities groups in Serbia) - totalling 67 letters which can be used for a domain name.^[7]
