Buypass ID in Mobile can be renewed upon login during the last 30 days before expiry. When renewed, new certificates are issued automatically.
If the certificates are not renewed before expiry, Buypass may require you to reverify your identity. In such cases, you must order a new Buypass ID in Mobile, which involves a new identity verification process. The service is provided at current prices.
