I use Alcazar Networks LRN product. https://www.alcazarnetworks.com/data_services_lnp_lrn.php $0.00025 per query, or $199/month for up to 50 queries per second (that's like 130 million queries a month!). They return the LRN for a DID, as well as the LEC, and some other stuff. If you include the CallerID of the caller, they will tell you if the call is interstate or intrastate. While intrastate rating of a call does not determine if it is local, it is likely better than nothing. We use it to determine our LCR rate deck rate for a call.

However, they do not offer AFAIK a premium or commercial option to get this data. https://telcodata.us/ has a lot of great LERG-adjacent data, plus a paid option, but I'm not sure if they have the data to determine if a call is local or not. You mention "coordinates/distance" between callers. Are you having the callers use an app with GPS location? Or are you operating on what information is in the LERG, where you know the switch location of an NPANXX, and whether or not the Caller and Callee NPANXX are considered "local?"

Does anyone know of any commercial products that can determine if a call is local?
The product would look at what is defined in the Tariff documents, not just make the decision based on coordinates/distance between callers.
I am aware of iConnectiv's solution.
Thanks
