Account Security
To prevent identity theft, we require identification when you start service. You may provide your Social Security Number (SSN), or, if you prefer not to submit your SSN online, you must instead provide two valid forms of identification (such as a driver’s license, military ID, or passport) via mail. Failure to provide or validate these within 15 days will result in service disconnection.
