To Start Service:  

Starting service at a new location

• Address where electric service will be established (i.e., service address)
• Billing address if different from the service address
• Service start date (i.e., Move-in date--example format:  03/03/16)
• Social Security Number (SSN)
• Second form of identification (e.g., driver's license number)

UI is committed to help prevent identity theft. When you start service with UI, we require at least two forms of identification (Social Security Number, driver’s license, military ID, or passport) so that we may verify your identity. If you do not wish to provide your Social Security Number via our on-line form, UI will send you a letter requesting two (2) forms of valid ID. If UI does not receive two forms of valid identification or is unable to validate your identification within 15 days, your service will be disconnected.
