Which city has the headquarter of World Bank?

Answer 1

Washington, D. C.

February 14, 2003—Ever since the World Bank opened for business on June 25, 1946 the address of its headquarters has been 1818 H Street N.W., Washington, D. C. During the first Board of Governors meeting in Savannah, Georgia, in March 1946, the city of Washington was chosen as the future site of the World Bank.

Answer 2

The IMF is small (about 2,300 staff members) and, unlike the World Bank, has no affiliates or subsidiaries. Most of its staff members work at headquarters in Washington, D.C., although three small offices are maintained in Paris, Geneva, and at the United Nations in New York.
The World Bank is a component of the World Bank Group, which is part of the United Nations system.
