Searching Providers

[dcman]

So, I have a handful of phone numbers that belonged to providers. I plugged them into the RM search and 2 of them pulled up 2 providers, the balance did not find anyone. Any suggestions how to expand this search to other sites and which sites? Also on RM search there is a field for New Listings but how does one keep track of what "New means". Having these phone numbers is great but how to use them to potentially locate the provider is proving evasive.. thanks for any suggestions.
