In May 2006, Trend Hunter featured Safe Talk temporary phone numbers for dating. Not too long after, Craigsnumber was in the game.
The service must be doing well as Craigslist has upped their investment, adding new features and a new brand. Lifehacker.org reports, "Numbr is Craigsnumber re-branded with a lot of cool new features. Numbr supports 23 US cities, can forward calls to up to 2 phones, blocks telemarketers, and offers a Do Not Disturb option from 9PM to 8AM."
Additionally, the application can also take voicemails and email you your disposable number's call history.
