And note that relatively few BNP Paribas Fortis banks have the right type of ATM that provide up to 99 :note-5:s in one go: you have to look for
Wincor-Nixdorf machines (on top of them you'll see a sign indicating that "5, 10, 20, 50, 100" are available); most other ATMs are Diebold machines that will only get you :note-10:s, :note-20:s, :note-50:s and sometimes :note-100:s.

The ATM that is the closest to the National Bank is at De Brouckère, Boulevard Anspach 3 / Anspachlaan 3, B-1000 Brussels.
