In my new phones caller ID I just see "California" and the number or "Unknown" this has always worked on my older phones. Is there something
I can do?
Caller ID should work as it always has. Check the manual gor your new phone to see if there are any settings options. It is not unusual to get, "out of area", "private Caller", "unavailable", or in some out of state calls the State name.
Let me reiterate that these aren't blocked calls, cell phone calls or out of area calls -- I actually get the name of the state, e.g., "Michigan," and a telephone number. I simply don't get the name of the caller. These are callers whose names DID appear before I switched to Verizon. Is the implication that out of state caller ID only works if the caller is a Verizon customer? That's less than useful, to say the least. I've talked to tech support a number of times, and while the reps are very professional and try to help, it's clear that they have no idea what to do about this.
For some people, Caller ID is just a handy extra feature. For us it's a deal breaker. We have both relatives and clients from other states and we need to know who is calling.
Well, that's good to know. I wonder why, in four calls to tech support and as many to sales, nobody could tell me that?
I understand that changing my service may not change anything. All I can tell you is that I never had this problem with Comcast. If that hadn't been the case I wouldn't be so upset about it. Maybe in the past, everybody who called me had Comcast service, who knows?
Granted, I had other issues with Comcast, which is why I switched. On the whole, our cable performance is better with Verizon, the phone service is clearer, and I have no complaints with the internet connection.
Anyway, thanks so much for your thorough replies!

Major landline carriers, cellular carriers, and interexchange (e.g. long distance carriers) conform to full FCC mandated (Feature Group-D) protocol requirements. That is, they send (or receive/display) Calling Number and Calling Name (aka Caller ID) information. Some COCOT phone companies and long distanceresellers may not fully conform.
Many large businesses that have their own/private systems and some VoIP providers use as 23B+D interface (to the Public Switched Telephone Network) which essentially allows them to decide (or modify) what is sent as Calling Number and Calling Name information. Many of these companies rely on this ability to intentionally mask what is sent as a Caller ID --maybe not ethical, but not illegal. Most marketing 'annoyance' calls are intentionally originated in this manner to mask their identity.
Verizon, and a few other cellular companies use the name of the state the call originated in as the Calling Name (but do transmit the Calling Number). Some cellular companies allow the subscriber to determine if their name is sent as the Calling Name.
That said, the signaling system (SS7) used is separate and distinct from the 'voice' system. While the voice Quality of Service protocols are intended to guarantee that (digital) voice packets do not get lost --though not necessarily so for VoIP--, the SS7 protocols do not guarantee that (digital) signaling packets do not get lost. Hence, a lost SS7 packet may result in an occasional 'missing' Caller ID message.
