If you’re joining the iPhone Upgrade Program for the first time, you’ll be asked to provide your date of birth, Social Security number, and annual income for a credit check. You’ll also need a valid U.S. credit or debit card. Prepaid cards are not accepted at this time.

Citizens One reserves the right to perform a credit inquiry as needed to determine loan eligibility. Depending on your account performance and transactional history in the iPhone Upgrade Program, Citizens One may approve your new loan application without your credit being impacted.
