The numbers might be actually invalid, or the area code and prefix may be for an exchange that isn't supported by any of our carriers. In this case, 690 is not a valid area code for either the US or Canada.

I try to upload a high number (5247) of phone numbers in the 450 and 514 areas.
The software only uploads 4557 of them, telling me that 690 are invalid numbers.
However, in my XLS file, those are all ten-digits numbers beginning with the area code.
What are the most common causes of invalid numbers in those cases?
