National [[expressways of China]] are designated with letter G (for 国家高速, ''guójiā gāosù'') followed by 1, 2, or 4 digits. For national expressways, one-digit numbers are used for expressways starting in [[Beijing]]. Two-digit odd numbers from G11 to G89 are for north–south long-distance expressways, and even numbers from G10 to G90 are for east–west long-distance expressways. Numbers G91 – G99 denote regional ring routes. Four-digit numbers indicate city ring routes, spur routes and parallel routes. The first two numbers indicates their parent routes, while for the three types of routes, the third digit is 0, an odd number, or an even number, respectively. Provincial city ring routes, spur routes uses two digits. For example, in G15<small>03</small> ([[G1503 Shanghai Ring Expressway|Shanghai Ring Expressway]]), "15" refers to the [[G15 Shenyang–Haikou Expressway]], which passes through Shanghai, and "0" indicates that the route is a city ring expressway.

Provincial expressways are designated with letter S (for 省高速, ''shěng gāosù'') followed by 1 or 2 digits. Similar to the national expressways, one-digit numbers are used for routes starting in the provincial capital. Since 2017, the Chinese route naming standard no longer designates provincial expressways with 4 digit numbers.<ref name="GBT9172017">{{cite book |last1=The Standardization Administration of the People's Republic of China |title= Highway route marking scheme and national highway numbering, GB/T 917-2017 |script-title=zh:[公路路线标识规则和国道编号 GB/T 917-2017] |date=2017 |publisher=Standards Press of China |location=Beijing}}</ref>
