† Due to the Number Portability Act, users can keep their telephone number when switching providers. They can move to any ZIP Code in the United States with the same NPA/NXX. Over time the connection between ZIP Code and Area Code has become less meaningful. In many cases there is no correlation at all and thus should not be relied upon any longer, in our opinion. We leave the ZIP Codes in the data for reference only, but not all ZIP Codes are represented.
