Before you can take a ride with Uber, you'll have to confirm your mobile number. If you change the phone number on your account, you’ll have to verify again to keep riding.
To confirm your mobile number, just text the word "go" to 827-222.
If you don’t get a reply saying that your number was confirmed or the response is "Message blocking is active,” your mobile service provider may be blocking you from texting our number. Give your provider a call to see if they will let you text 827-222.
Google Voice users may have to login to http://google.com/voice in order to text the word "go" to 827-222.
