During the RRM Registration  process, which form should be filled out and uploaded when requesting a  digital certificate from the Agency?

Answer: In case where the certificate is requested for a physical person (e.g. for registering the RRM Admin account), the ACER-PO.pdf form must be used.

When a certificate is requested for the purposes of authenticating a machine communication (e.g. when establishing a WebService or SFTP interface with ARIS), the ACER-PSN.pdf form should be used.

Both forms are available here: https://www.acer.europa.eu/remit-documents/remit-reporting-guidance
