BGN/PCGN romanization

{{Short description|US/UK government romanization methods}}

BGN/PCGN romanization are the systems for romanization and Roman-script spelling conventions adopted by the United States Board on Geographic Names (BGN) and the Permanent Committee on Geographical Names for British Official Use (PCGN).

The systems have been approved by the BGN and the PCGN for application to geographic names, but they have also been used for personal names and text in the US and the UK.

Details of all the jointly approved systems are outlined in the National Geospatial-Intelligence Agency publication Romanization Systems and Policies (2012),{{cite web|title=Romanization Systems and Policies|url=https://geonames.nga.mil/geonames/GNSHome/reference.html#bgnroman|publisher=National Geospatial-Intelligence Agency|date=30 May 2024|access-date=25 Nov 2024}} which superseded the BGN 1994 publication Romanization Systems and Roman-Script Spelling Conventions.{{cite book |author= US Board on Geographic Names |title = Romanization Systems and Roman-Script Spelling Conventions |publisher = Defense Mapping Agency |year = 1994 |url=http://libraries.ucsd.edu/bib/fed/USBGN_romanization.pdf |archive-url=https://web.archive.org/web/20131023055657/http://libraries.ucsd.edu/bib/fed/USBGN_romanization.pdf |archive-date=2013-10-23 |url-status=dead |format=PDF |access-date=8 January 2013 |oclc=31881487}} Romanization systems and spelling conventions for different languages have been gradually introduced over the course of several years.
