Who I have the same questioned this topic

I am running Verizon Message+, v.6.4.39 on a recently purchased Moto Z Droid, and using the Verizon network.  Today, I sent a group message.  I got replies from these people that my number showed up as a completely odd number (incorrect area code and phone number).  Additionally, all other contacts in the message to the recipients only showed up as numbers, not as the contact names.  The people that had the problem are on the Verizon network, using an iPhone, and NOT using Message+.  To me, this still does not explain why my number would show up to them as completely incorrect.  Can Verizon please advise the status of this issue?
