Shift will begin the registration process once the 7 day return period has passed. It typically takes 30-60 days to receive the registration to the address specified in your registration documents, but at times it can take up to 90 days.
At times, external factors may delay the registration such as DMV processing times, and internal processing requirements. That being said, Shift will do whatever it can to ensure the registration process is smooth and as quick as possible.
