On invoices issued by a Slovak supplier or on commercial letters, the account number is usually structured as shown in the second column. In these cases

  • the separators used between the firs part and the second part of the account number are shown as blanks, hyphens or slashes
  • the Bank code is preceded by a slash.

Check algorithm

A Modulus 11-check algorithm with weights is used to validate the account number structure. The weight table to be used for

  • the first part (prefix) is 10,5,8,4,2,1
  • the second part (basic) is 6,3,7,9,10,5,8,4,2,1

To validate the first and second parts of the account number, the digits are multiplied by their respective weights, added up and divided by 11. The remainder must be zero.
