I'm writing a program that can find info about a phone number. One problem appears to be that Google's phone number library doesn't provide enough info. For instance, take this number: +1 (613) 745-1576. My iPhone correctly says "Ottawa, Ontario, Canada", while Google's library doesn't return the city? How does my iPhone pick this up but not Google's own library? Is this provided by cell carriers? Is it something with the 745 block? If so, where can I find this info?

I edited a little onto my original reply about the 2nd 3 digits of a North American phone number.
