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.
