Tongyong Pinyin
Postal romanization remained official in Taiwan until 2002, when Tongyong Pinyin was adopted. In 2009, Hanyu Pinyin replaced Tongyong Pinyin as the official romanization (see Chinese language romanization in Taiwan). While street names in Taipei have been romanized via Hanyu Pinyin, municipalities throughout Taiwan, such as Kaohsiung and Tainan, presently use a number of romanizations, including Tongyong Pinyin and postal romanization.
