Yes there is, although it does have a third category for, basically, 
number from abroad, whose status is unknown.  It has been introduced fro 
all VoIP in the USA.

Providers have to sign information that indicates whether caller ID is 
the true caller ID, or another caller ID from someone they have 
positively identified.  (A and B attestations; C is the third case 
above.)  I haven't gone into the details of how the true identity is 
tracked, but, if it isn't included in the VoIP headers, I assume that 
the provider must log it and provide it to the authorities.

Search STIR/SHAKEN for more information.

Unfortunately this has been cross-posted to world as well as UK groups, 
and I suspect you are in the UK.  Also the real problem is associated 
with VoIP, and it hasn't been posted to a VoIP group.

I believe that the UK didn't want to use the extension to the 
traditional PSTN, and is awaiting analogue switch off, before fully 
implementing the same, or similar.

I believe many US legacy network users see a "V" in the caller ID, if it 
is a true caller ID of the caller.

I believe there are mechanisms for passing on authentication when an 
call is forwarded, but it's something I've researched in depth, only 
noting that complying has tripped up many US VoIP using organisations, 
who used to like forwarding original caller ID to outworkers.
