Transferring a line from one Verizon account to another: "Account device cap exceeds" error

YourUsername1

1. A line transfer request was initiated from the "sending" account
2. The "receiving" account owner received the email, clicked on the link, followed the instructions
3. During the Review and Accept Service Transfer screen the error at the top says, "Account device cap exceeds". The Next button is greyed-out, there's no way to proceed. Plus, there's no help or even a normal English error message.

This failed the first time a month ago. I called Verizon customer service and was told to try again later, they were having system problems. So we let the first transfer request expire and just initiatived a new one which failed in the same way (I'm not calling again).

So then I tried to add another line through my Verizon account (bring your own device, etc) and got pretty far. But now on the Enter Current Carrier Account Information screen under the "Phone number you're bringing" box is an error message that says, "Sorry! That number can't be transferred. Please call us or reach out to the nearest Verizon store". No thanks.

Transferring a mobile line between two VERIZON accounts should be easy, right? If we're not doing something right, at least give us the information to fix it. Somewhere in the Verizon system is the reason each of these methods doesn't work and the people who programmed these functions decided it's best to not share that with customers? Instead, make them call customer service (and wait for help) or visit a Verizon store (and wait there for help).

Verizon has worked so hard over the past 10 years to bring us faster data speeds and faster devices yet it's acceptable to make people wait for customer service for something this simple?

Better yet, do you have an idea to solve this transfer request without having to wait for customer service?

UPDATED: The problem was found to be the destination account for the transfer. The plan type was only for a single line. I had to call Verizon support to get the destination account changed to a multi-line account, then the transfer was completed.

We tried at least 5 times to do this transfer online, called Verizon support about 5-6 times (on both sides) over the past 4 months and only the most-recent phone support person was able to figure out the problem.

Verizon, please update the error message when attempting to transfer an account from "Account Device Cap Exceeds" to "Destination account does not have enough available lines for the transfer. Update the destination account plan and re-try the transfer request. See verizon.com/XYZ or call 1-8[phone number removed per the Verizon Terms of Service] for instructions". A message like this would've saved me hours on the phone with Verizon support. Please make this change, thanks.
