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?

Where I live carriers allow you to relocate your landline number to a new address when you move out nowadays, so this might be an issue to keep up to date.
