Finnish Reference Number

    Reference number based on the Finnish standard 
    The Finnish reference number is used in domestic payments. In order to avoid typing errors, the reference number should be short, but no shorter than four (4) digits (three digits and a check digit). The maximum length of a reference number is 19 + 1 digits. The reference number is printed in the field reserved for it in groups of five digits separated by an empty character space. The leading zeros are not printed. The reference number must also be included in the part comprising the invoice, if any. Guidelines to the structure of the creditor reference are annexed to this document.


    An example of the reference number, given in paper format and machine readable format (respectively): 
    12 34561 
    Calculation of check digit

    The calculation of check digit is done using 7-3-1 method:

    1.     The digits in the basic reference data to be verified are multiplied by the weights 7, 3, 1... right to left .
    2.     The multiplied sums are added up
    3.     The sum is subtracted from then nearest figure ending in zero.
    4.     The resulting difference is the check digit, which is entered as the last digit in the reference number.

    Finnish reference in XMLdation service

    Finnish reference check is active for all Finnish pipes, and is executed unless RF Creditor Reference is used.

    Despite FKL stating that length of finnish reference should be 4-20 characters, validator accepts 3-20 characters, as "123" is considered to be valid reference according to certain Finnish banks. 

    Validator accepts both paper and machine readable formats of Finnish Reference.
