Your don't have to be a nefarious crime lord from The Wire to occasionally want a phone number with a limited life span. For example, let's say you've got a week long Craigslist sales listing, and you're willing to have potential buyers (or sellers) call you for that one week only. You need a burner, a temporary phone line alias. The $2 Burner app will produce a number with preferred area codes in mind and even supports SMSm outbound calls, and texting, all without revealing your real digits. Stringer Bell approved.
