E.Leclerc operates numerous stores and services around France, some near and in cities and towns while most of them are located just outside or in the hypermarkets and shopping centres.

[8][9] Over the years, several spaces were founded such as Le Manège à Bijoux in 1986, E.Leclerc Voyages in 1987, L'auto E.Leclerc in 1988 and the Parapharmacy E.Leclerc in 1988 after the end of the pharmacists' monopoly on sales.

In 1973, Édouard Leclerc invented the concept of wine fairs, which he launched in his supermarkets.

During 1998, E.Leclerc and the Système U group joined forces and created a common purchasing center called "Lucie".

[11] The E.Leclerc cooperative is composed of several regional central buying services that operate the group's stores in their respective areas.

In 2023, E.Leclerc expanded into Luxembourg by acquiring the local branch of the Louis Delhaize Group, which operated 2 Cora hypermarkets and 25 Match and Smatch supermarkets.

Stores started to operate under the E.Leclerc brand in the spring of 2024; this was the retailer's first international expansion in 13 years.
