It forms part of the boundary of the Staffordshire-West Midlands County border, along with Perton, the village is almost contiguous with Wolverhampton with very small amounts of greenbelt still separating the two settlements.

Agriculture was the mainstay of the village and even now the strip-field system of cultivation can be seen to the west and north-east of St Nicholas' church.

Development took place along Station Road and beyond with some substantial properties being built to accommodate wealthy businessmen from Wolverhampton and the Black Country.

Gradually the focus of activity changed from the area around the church and the station to the crossroads or 'Square'.

Emphasis on the Square was increased after 1900 when Baker's Nurseries expanded on the site of Old Hall Farm in Church Street.

The growth of public transport, with a terminus for buses to Wolverhampton in the Square, the coming of electricity and the digging of the deep sewer all in the 1920s, helped to change the function of the village from an agricultural centre into a dormitory for Wolverhampton.

Codsall has expanded since World War II, forming the largest part of three adjoining villages (the others being Bilbrook and Oaken).

In the village, Codsall Community High School runs a post-16 Football Academy for their students.

Codsall along with neighbouring villages Perton, Wombourne, Himley, Swindon, Featherstone and Essington form part of a built up area[3] of South Staffordshire around the West Midlands County (Wolverhampton and Dudley) and Shropshire (Cosford and Albrighton).

Codsall Community High School was judged to be good by Ofsted in November 2013.
