Freeways in Taiwan are officially coded "National Highways" with their respective numbers. By this principle, Freeway No.3 is coded National Highway No.3 (國道三號) in official documents or on road signs. Besides the numeric name, from 1st November 2004 it is also called Formosa Freeway (福爾摩沙高速公路) after a name-giving competition; however, its old alias Second Freeway (第二高速公路 or 二高) is more popular among the road users.

The total length is 430.5 km, with 55 interchanges, 13 junction interchanges, 11 toll stations, and 7 service areas enroute. Besides the 55 interchanges of servicing usage, there are also some interchanges only for governmental usage.
