Doesn't work for Ireland either. But even if you have an unlisted number, the number of people who'd have access to where you live is still pretty long. Phone companies, gas, electricity, banks, libraries, airlines (if you've ever flown), and even taxi companies. Just found out if you book a taxi most companies will keep your details on file. Which was kinda freaky coz I rang a taxi from home yesterday, and the little recording voice came on with the usual "Thank you for calling..." then said "Press 1 to book a cab, press 2 for..." So I pressed 1, thinking I'd get put through to an operator. Instead, the same voice said, "Thank you, Tim, a taxi is now on it's way to [my address] now, and should arrive in 10minutes." Even stranger, 15mins later, my mobile phone rang and the little voice said, "You taxi is waiting outside." Freaky. Just plain freaky.
