FCC guidelines state that the porting process should be completed within 2 hours of scheduling. However, some wireless carriers still process a percentage of requests manually. Because of this, some carriers warn that the process may take up to 4 days to complete. We have more experience handling number portability requests for every major U.S. carrier than any retailer or web site, and we make every effort to schedule your number transfer with your shipment so that it will occur within 24 hours after you receive your phone.
