The only companies required to report NRUFs are the companies whose name
appears as the code holder or block holder on the NANPA / Pooling report
and in the LERG. The purpose of the NRUF report is to forecast the
future need for 10K and 1K NXX blocks down to the rate center level.
Utilization which is reported on the U1 page is broken down into 5
different categories. (Assigned, Intermediate, Reserved, Aging, and
Admin). The number of TNs ported from each block is NOT reported on.
Since only the carrier of record on the NAS / PAS reports has to file
NRUFs, they are also the only companies that report on Intermediate
numbers. Intermediate numbers only indicate the number of TNs "leased"
from each block that are being resold through other wholesale carriers.
What's reported on NPAC by SPID will never match up with the NRUF
because the SPID is not tracked on the NRUF. Only the name of the
carrier each block was originally signed to.

“Resold” services should also be treated like ported numbers,
meaning the carrier transferring the service to another carrier or
non-carrier entity should classify the numbers as “Assigned” and
the numbers should not be counted by the receiving carrier. These
numbers should not be considered intermediate numbers because the
intermediate classification only applies to blocks of numbers obtained
from or given to another carrier or non-carrier entity for future
assignment. Numbers transferred with resold services already have
established customer assignments and therefore cannot be used for
future assignment.
So it seems like if I transfer a block to someone else (anyone but an
end-user) for them to maintain in inventory or we receive a block of
number from someone else, then that's an intermediate number. If it's
on a ones-and-twos basis, fulfilled per end-user request, then it's an
assigned number. That seems difficult to maintain an accurate count
of. If I request numbers from VoIP.MS, Bandwidth, Peerless, etc., it's
an assigned number.

What are some examples of when someone would report intermediate
numbers? The documentation gives a technical answer, but not a
real-world example.

I'm just learning about NRUF 502.
As I read the documentation (and some Googling):
Every phone number in the blocks I have are either Assigned,
Intermediate, Reserved, Aging, or Administrative.
Ported out numbers count as assigned.
Returned ported numbers are available.
I do this for blocks that I got from NANPA.
I do not do it for ported numbers.
I'm supposed to be able to tell in Neustar SOA what numbers have
disconnected. I've reached out to them to figure out how to do that. I
couldn't find documentation that was direct enough for me to know it
was the right thing.
