However, because seals act like legal signatures in the cultures of China, Japan, Korea, and Vietnam, and because vermillion seal impressions are a fundamental part of the presentation of works of art such as calligraphy and painting, seals and therefore seal script remain ubiquitous. Most people today cannot read the seal script, so it is considered an ‘ancient’ script, generally not used outside the fields of calligraphy and carved seals. Although seals (name chops), which make a signature-like impression, are carved in wood, jade and other materials, the script itself was originally written with brush and ink on bamboo books and other media, just like all other ancient scripts.

Today, this style of Chinese writing is used predominantly in seals, hence the English name. Although some modern calligraphers practice the most ancient oracle bone script as well as various other scripts older than seal script found on Zhōu dynasty bronze inscriptions, seal script is the oldest style that continues to be widely practiced. The seal script (often called 'small seal' script) is the formal script of the Qín system of writing, which evolved during the Eastern Zhōu dynasty in the state of Qín and was imposed as the standard in areas Qín gradually conquered.
