Congrats on the recent upgrade! Being able to resell your old device is always a good thing, and I'd be happy to help you out with this information. To begin, was the iPhone you purchased done through Verizon, or was it purchased at another reseller (Best Buy, Authorized Retailer, Amazon, etc.)? The reason I ask is due to the original seller of the device controls the locking capability, so if it wasn't purchased through us, you'd need to reach out to the original seller. For more details regarding our unlocking policy, check out this link: http://spr.ly/6609Giywl.
I can understand your concerns regarding your device being unlocked. Devices that you purchase from Verizon are locked for 60 days after purchase. You can view these details here https://www.verizon.com/about/privacy/consumer-safety/device-unlocking-policy. Why are you looking to have the device unlocked? - AlbertoR_VZW
