Search by phone number
It would be neat if you could test for pwned accounts searching by phone number. Some utility companies know my phone number but not my email.
I've been thinking about this too. This goes along with Troy's recent inclusion of spam lists -- people want to know their total information exposure.

Currently not all breached include a phone number, but all contain an e-mail address. Searching for a phone number could give the "illusion" that you're safe, while you may be not.
Let's wait for Troy to learn more.
