As of May 2006[update], 77 establishments have been opened throughout the Netherlands. Together they have a market share of 3.4% in the Netherlands as of 1 January 2006. Jumbo's marketing claims that the chain has "7 certainties" with which they, among others, claim to have the greatest choice for the lowest prices.
The head office and distribution centre are situated in Veghel, (Noord Brabant), also Jumbo has 3 regional distribution centres: Beilen, Drachten, Den Bosch. In October 2005 a Jumbo was also opened in Drenthe province, namely in Valthermond. With the opening of this store, there is now a Jumbo in every province in the Netherlands. Although Jumbo now has shops in the whole country there are relatively few Jumbos in the Randstad.
On 23 November 2011 it was announced that Jumbo would take over all C1000 stores. Because of this Jumbo became the second largest supermarket chain in the Netherlands, right after Albert Heijn. But this would not mean that the C1000 stores would disappear, many of them were never changed to Jumbo.
