There is no fee to port a number with Twilio, and once you port it in it is $1/month to hold onto the number. To port, you log into your Twilio account and visit the phone numbers tab and select "port number", or hit this URL https://www.twilio.com/user/account/phone-numbers/porting

At this point, you fill out a form asking for the billing information and then we follow up with you to get authorization to transfer the number (usually just a signature). It usually takes about 10 business days to complete the port.

(I work at Twilio too)

Thanks for the follow up. What do you accept as billing information for a Google Voice number? That's the part I got stuck on. Is this merely a formality? Is a screen shot of the account page acceptable? As a free service, they have never sent me a "bill".

I'm pretty sure we accept a screen shot of the account page.
