Under the new rule, customers will have to verify either their e-mail address or phone number within 15 days of applying for a domain. Without verification, registrars are instructed to suspend domain registrations. On top of that, registrars will be required to maintain information of clients, including details like credit cards, for two years after users cancel their registrations.
Other information like the IP address used to sign up for a registration needs to be recorded and given to ICANN at its request for up to 180 days. Registrants will also need to update their contact information within seven days of any change under the new rules, though it's unclear how that will be enforced — the old rules only provided for 15 days to update such details and data was often outdated.
