Like ANSI in the US, GB standards fall in many areas. Mandatory standards are prefixed "GB". Recommended standards are prefixed "GB/T" where the letter T is from Chinese tuījiÃÂ n (推荐, recommended). A standard number follows "GB" or "GB/T".
The following is a partial list of widely used National Standards of the People's Republic of China. Compared to many international standards of ISO, many standards are identical (IDT), equivalent (EQV), or non-equivalent (NEQ).

National Standard Encoding
In computer contexts, "GB" alone is often used to mention GB 2312-1980 issued in 1980, or GB 18030-2000 issued in 2000. These two are encoding standards for encoding Chinese characters.
This character encoding method is used to code for Simplified Chinese characters, which are used in Mainland China and Singapore. Taiwan and Hong Kong, which use Traditional Chinese characters, have Big5 as their standard.
There are about 7200 characters in the GB 2312-1980 codeset, versus approx. 16000 in the Big-5 codeset. The pinyin, romanization of these characters, is standardized as well. It can be used as one of the several Chinese input systems (e.g., by typing Z-H-O-N-G for the character 中)
