DIA opened its first store in Madrid’s Saconia neighborhood in 1979 with a hard-discount format focused on value and convenience. The company introduced private-label products early in its development and later adopted franchising, which became an important part of its neighborhood-store model.
The modern business emphasizes proximity food retail rather than the large-format hypermarket model. Stores combine fresh and packaged groceries with DIA private-label products, while Club Dia, the mobile app and online ordering add loyalty and digital-shopping functions. Store format, assortment and delivery availability vary by location.
DIA has changed its international footprint over time. Its current core business is focused on Spain and Argentina, so older descriptions that present Portugal, Brazil or China as current major operating markets can be outdated. The group is headquartered in the Madrid area and has been listed on Spanish stock exchanges since 2011.
In Spain, customer service is available by phone at 91 217 04 53, WhatsApp at 686 20 20 90 and email. Online grocery issues use compraonline@diagroup.com, while general account, store and Club Dia matters use the main customer-service route. Official Spanish social channels include Facebook, Instagram and X.
