Get a NANPA database subscription and compare the rate centers.
There is a database available on their website. It isn't accurate for billing purposes, but I've found that it is accurate enough for a conservative lookup and to add a little logic to a provider's list. It has the area-code and prefix matched to a rate-center. If the rate-centers are the same, then the two numbers are probably either local or local-toll. YMMV.

- My only point I guess is that if you are in a position where you are handed a list of number from a network provider which owns them it's tough to know if they handed you some bum numbers on that list.

- This would be true.
- However, we have had many occurrences of the carrier presenting these numbers as �local� to the end user without ever checking with the telco (when indeed they were not local calls). I speak from both sides of the issue (telco/isp) J
- In these cases, it�s pretty clear that the carrier has an issue.
