(1) The supplier of the residence is obligated to cooperate when it comes to the registration. To that end, the supplier of the residence or someone commissioned by him or her is required, within the period stated in section 17 (1), to send confirmation of a person having moved in either in writing to the person required to register or also electronically to the registration authority in accordance with subsection (4). He or she may contact the registration authority to find out whether the person required to register has registered. The person required to register is to provide the supplier of the residence with the information necessary to confirm that the former has moved in. The confirmation referred to in sentence 2 may only be issued by the supplier of the residence or someone commissioned by him or her.
(2) If the supplier of the residence or the person commissioned by him or her refuses to provide confirmation, or if the person required to register does not receive confirmation in a timely manner for other reasons, the person required to register is to inform the registration authorities thereof without delay.
(3) The confirmation provided by the supplier of the residence contains the following data:
1. the name and address of the supplier of the residence and, if that person is not the owner, also the name of the owner,
2. the date moved in,
3. the address of the residence and
4. the names of the persons required to register in accordance with section 17 (1).
(4) If the confirmation is provided electronically to the registration authority, the supplier of the residence receives a reference number, which he or she is to notify to the person required to register to use when registering. Section 10 (2) and (3) applies accordingly. If the registration authority makes available other means of authentication as regards the supplier of the residence, it is to be ensured that measures as referred to in Articles 24, 25 and 32 of Regulation (EU) 2016/679 are implemented.
(5) The registration authority may require the owner of the residence and, if the owner is not the supplier of the residence, also the supplier of the residence to provide information concerning persons currently living at his or her residence or who lived there in the past.
(6) It is prohibited to offer or make available to a third party the address of a residence for the purpose of registration in accordance with section 17 (1) if the third party neither moves into the residence nor intends to do so.
