Show Dutch bank account number This tool can randomly generate Dutch bank account numbers which are Elfproef valid.

Elfproef (Dutch for Eleven test or 11 test) is a test that is used to validate Dutch bank account numbers. It is a rudimentary check to validate the correctness of the bank account number.

The bank account numbers are randomly generated and may not actually exist.
Dutch bank account numbers have maximum 10 digits.

You can select the following Dutch bank account numbers:
  • 10 digits (Elfproef)
  • 9 digits (Elfproef)
  • No
If you select No, the column with Dutch bank account numbers are not displayed.

You can also enter a start value. This value is used as the starting point to calculate the Dutch bank account numbers in a sequential order.

If 9 digit bank account numbers should be generated you must enter a start value with 9 digits. Do not prefix with 0.
