This is a VERIZON customer service number... with that said, do not trust your caller ID. Criminals have the capability to "spoof" numbers on caller ID. With the right hardware, they can make any number show up in your caller ID...
I received a call from this number after being accidentally disconnected from Verizon customer service. The person calling was the same person at Verizon that accidentally hung up on me. No phishing involved. 100% legitimate.
We had people hijack our phones for the 4th time, then I got a phone call from this number, we were already on the line with Verizon at the time so why would they be calling us when we were already talking to them about the hacking?????
This is a number that calls to try to get your information and then take over your account. In most cases your wireless carrier. When you call it back its always busy, when they call you they do not leave a message, and they have no answering machine.
