What this can show
Country and calling-code results link to the full reference pages. Shared codes link to every supported assignment. Exact NANP area codes retain their country context; reviewed regional codes link to the matching row in the country table.
Codes, not subscriber information. A full phone number is not validated here. Prefixes are checked as entered; 00 or 011 is not removed without knowing where a call starts. This reference does not identify subscribers, current owners or carriers, exact locations, or spam reputation.
