3276143 - How To Configure Finland Henkilötunnus National ID in Manage Business Configuration (BCUI)


Due to a legal change in the validation of the Finland Henkilötunnus National ID, a configuration change in Manage Business Configuration (BCUI) is required. The legal change will be effective on 1st January, 2023 onwards.

  • National ID


The sufficient availability of personal identity codes is ensured by introducing new punctuation marks. The current personal identity codes will not be voided, which means that the personal identity codes that have already been granted, would remain unchanged.

The new letters are:

  • For those born in the 2000s: Letters B, C, D, E and F will be introduced alongside the letter A currently in use.
  • For those born in the 20th century: Letters Y, X, W, V and U will be introduced alongside the hyphen currently in use.

The configuration change can be done either through BCUI or CSF SDM. 

Change Through Manage Business Configuration (BCUI):

  1. Navigate to Admin Center and select Manage Business Configuration
  2. Expand the HRIS Element nationalIdCard
  3. Click on nationalIdCard_FIN
  4. In the field Regular Expression replace the existing expression [\d]\{6\}[A-]\{1\}[\d]\{3\}[0-9 A-FHJK-NPR-Y]\{1\} with the new expression

Change in Country-specific Succession Data Model (CSF SDM):

Download the CSF SDM, open the file and go to the following section:

  <country id="FIN">
    <format-group id="national-id">

      <format id="HETU">



        <reg-ex>[\d]\{6\}[A-]\{1\}[\d]\{3\}[0-9 A-FHJK-NPR-Y]\{1\}</reg-ex>



You have to change the reg-ex to the new format as shown below:

Once the change is saved, please upload the modified CSF SDM file. You may need access to Provisioning for uploading CSF SDM. If you do not have access to Provisioning, please consider making the change through BCUI or you may contact your implementation partner. 

The code level validation of the new changes should be effective from 12th December, 2022 in Preview environments and 15th December, 2022 in Production environments. If there are any changes in the schedule, we'll update this article.
