You can return your OBU on the Road User Portal or at a Service Point.
After returning the OBU
Satellic will perform an independent assessment with regard to the repayment of the OBU Deposit, and this decision will be communicated to the e-mail address you provided to Satellic. If Satellic determines that you have the right to a repayment of the OBU Deposit and if a valid bank account (IBAN and BIC) number has been entered at the Service Point or on the Road User Portal, your OBU deposit will be refunded within 30 days following receipt of the returned OBU.
