And in case you were wondering, this is not some sort of regional division. The two companies are legally separate entities that both use the Aldi name.
In Germany, Aldi Nord (HQ: Essen) has slightly more stores at 2,298 in western, northern, and Eastern Germany compared to Aldi Süd’s (HQ: Mülheim) 1,880 stores in western and southern Germany.
According to brilliantmaps.com, the border between their territories in Germany is commonly known as the “Aldi-Äquator” (Aldi equator). East Germany, is almost entirely severed by Aldi Nord, except for one Aldi Süd store in Sonneberg, Thuringia.
And perhaps even more interesting is that this division carries on to the rest of the world, as the map below shows:
