The Postbank is a large Dutch bank, part of the ING Group. It has 7.5 million private account holders and is hence one of the largest providers of financial services in the country. It provides current and savings accounts, loans, mortgages, insurance, investments and pensions. As opposed to other banks, it has no branches but operates completely through land mail, telephone and telebanking, although some operations have traditionally been available through post offices.
It was founded in 1881 by the national government as the Rijkspostspaarbank (National Postal Savings Bank). In 1986 it was privatised, together with the postgiro service, as the Postbank. A merger in 1989 with the NMB Bank led to the creation of NMB Postbank Groep, and a further merger with insurer Nationale-Nederlanden in 1990 created the ING Group. At 16th of May 2007 ING Group announced to merge its ING Bank together with its brand Postbank in The Netherlands to one single brand and new bank in 2009: ING.
