{{Main|Romanization of Bulgarian}}

A system based on [[scientific transliteration]] and [[ISO/R 9:1968]] was considered official in Bulgaria since the 1970s. Since the late 1990s, Bulgarian authorities have switched to the so-called [[Romanization of Bulgarian#Streamlined System|Streamlined System]] avoiding the use of diacritics and optimized for compatibility with English. This system became mandatory for public use with a law passed in 2009.<ref>State Gazette # 19, Sofia, 13 March 2009. (in Bulgarian)</ref> Where the old system uses <č,š,ž,št,c,j,ă>, the new system uses <ch,sh,zh,sht,ts,y,a>.

The new Bulgarian system was endorsed for official use also by UN in 2012,<ref>{{cite web |url=http://www.eki.ee/wgrs/rom1_bg.htm |title=UN Romanization of Bulgarian for Geographical Names (1977) |work=Eki.ee |access-date=2015-06-27}}</ref> and by [[United States Board on Geographic Names|BGN]] and [[Permanent Committee on Geographical Names for British Official Use|PCGN]] in 2013.<ref>{{cite web|url=http://earth-info.nga.mil/gns/html/Romanization/Romanization_Bulgarian.pdf |title=Romanization System for Bulgarian, BGN/PCGN 1952 System |website=earth-info.nga.mil |publisher=[[National Geospatial-Intelligence Agency]] |archive-url=https://web.archive.org/web/20071219024011/http://earth-info.nga.mil/gns/html/Romanization/Romanization_Bulgarian.pdf |archive-date=December 19, 2007 |url-status=dead}}</ref>
