Verizon received mine on Oct 4th and still haven't processed it yet. Most people here are reporting that it takes approximately 1-2 weeks from when Verizon receives it, not sure why mine is taking much longer though. So, I contacted Verizon's trade-in team to find out what's going on as nothing has been updated on
https://www.verizonwireless.com/device-status/ and I was told that it takes 3-6 weeks for that site to update once they receive the device(s). Good luck and for those who took less time, you're lucky!
