On occasion, it might be useful to have a disposable phone number. For example, you might want to list something on eBay, or (for the old timers out there) maybe you’re just selling something in the newspaper. So you could publish a temporary phone number that would be forwarded to your regular phone, and people could call you to ask you for more information. Then, when the auction ended or the item sold, you could just cancel that phone number and never think about it again.

Enter iNumber.

As this article points out, this service isn’t really necessary if you have Google Voice, but if you just need a quick disposable number, you might not want to set up an entire Google Voice account. Just go to iNumber and do a one and done.
