Transfer Procedure

NO auth code required for registrar transfer in standard Registrant Model. Transfer completes in seconds. For Registrar Management Model: auth code CAN be requested via Punktum dk self-service portal.

Do NOT make changes at Punktum self-service portal directly if managed by registrar. This creates serious discrepancies (billing contact change transfers domain away from registrar).
