Your billing address will be the location where your invoices will be sent to. For security reasons, 4sgm.com does not allow customers to make address changes online. You will only be permitted to make changes after you complete the registration form and send a request online to change your billing address.
By law, California residents must provide a copy of reseller's permit and which state it was issued.
