    Country-code top-level domainsIDN

    Overview

    • .rs is the Internet country-code top-level domain (ccTLD) assigned to Serbia.
    • The domain is managed and sponsored by the Serbian National Internet Domain Registry (RNIDS).
    • The two-letter code "rs" stands for Republika Srbija (Republic of Serbia).
    • DNSSEC is supported for .rs zones.
    • Registered domains: 132,047 (data as of 25 May 2023).

    History

    • July 2006: RNIDS was founded by the Serbian Ministry of Science and a group of organizations to operate the national domain.
    • September 2006: ISO 3166 Maintenance Agency allocated the country code RS for Serbia.
    • 24 September 2007: .rs was added to the DNS root zone (IANA delegation activities began in September 2007).
    • 10 March 2008: Registration of .rs domain names commenced.
    • ICANN resolved that RNIDS would temporarily operate the former .yu domain during a transition; the .yu domain expired on 30 March 2010.
    • 2018: Commercial marketing targeted .rs domains to entities in Brazil's Rio Grande do Sul (which uses the RS code).
    • 2018: RNIDS enabled registration of domain names using Serbian Latin letters and other minority Latin-script characters (totaling 67 letters for use in domain names).

    Usage and Audience

    • Intended for entities connected with Serbia and is mainly used within Serbia.
    • Typical users and audiences include businesses, non-profits, educational and research institutions, government bodies, and individuals.
    • The TLD is also marketed in specific contexts outside Serbia (for example, to organisations in Brazil's Rio Grande do Sul that share the RS code).
