I (telcodata) do have an archive of the NANPA data files and the CNAC
taken 3 times a week since 2020-10-28. Not sure if they'll work for you.

What are some recommended sources of number data, as it has changed
over time? I only need from 2019 onwards, anything before that is less
useful the older it is.
Firstly the actual number data:
Activate/Deactivate/Reactivate/Reassign NPA, NPA-NXX, Thousand Block, TN
Mobile/Landline
I presume everything but TN can be obtained from NANPA or National
Pooling reports. I think neustar PortPS might have TN porting history,
are there any lower-cost alternatives?
Then the related data I'm looking for:
Latitude & Longitude (Rate Center and Switch, for different reasons)
Address data like City, State, Zip, or City, Census Division,
Province/Territory, Postal Code (not specific TN addresses)
Population
I'm aware of telco-data and localcallingguide, but not if they have
historical data.
