The caller ID on this and all other Verizon phones (Android and other types) occasionally displays a "1" before the phone number. This causes the tenth digit to not appear in the caller ID. How can the "1" be prevented from appearing?

Question

Verizon's caller ID delivery system occasionally inserts a 1 before the phone number of the incoming call.  The caller ID feature appears to be poorly planned and executed by Verizon.  The caller ID feature should display more numerals so the call can be returned.  Can the iPhone 6 and all other phone-types on Verizon be configured to omit the 1?  This looks like it could be issued as firmware update.

Answer 1

Update - I called the number I was given for "ordering", and got the same phone tree I had the first time I called the number on Verizon's web site. At no point was there an option of "ordering". So I navigated back to FIOS tech support. The guy there said he called "ordering" and confirmed that the right name was in the Verizon directory. I asked him to push the directory entry, and he said he did that. I haven't had a chance to call people and see what shows up on their Caller ID.
I told the support person about the bill collectors calling for {edited for privacy}. He was full of nonsense. He said maybe {edited for privacy}gave out the wrong number. I pointed out it would be pretty hard for {edited for privacy} to put their name in Verizon's Caller ID directory, and maybe {edited for privacy} had my phone number before me. He looked that up and confirmed that my number previously belonged to {edited for privacy}.
I asked the support person if they provide their Caller ID directory to bill collectors, and if I was getting these calls because they have been selling a database that says {edited for privacy} still has my number, which has been my number for nearly two years. The customer support representative WOULD NOT ANSWER THIS QUESTION. All he would say was there is no way for Verizon to control who calls my number. That's not what I asked him.
I am very unhappy with Verizon, and I suspect until I called yesterday, they had my number associated with {edited for privacy} and they have been providing this erroneous information to bill collectors. I understand that each phone provider maintains their own Caller ID database, but I don't think it is credible that some other phone company's caller ID database would be two years out of date without some screw up by Verizon.
No Kudos. I see Google Voice in my future.
