QUESTIONS

Which area codes are covered?
The United States, Canada, Puerto Rico, and the US Virgin Islands. An area code outside those comes back as an honest miss, never a guess.
Why the state and not a city?
An area code covers a whole region, and overlay codes share the same ground. The state is the honest grain. Naming one city would be a guess.
Can I do this from code?
Yes. The state ships on every phone parse, so this is one GET /phone/{number} call. Same endpoint on every plan, one pooled request per lookup.
What about carrier or line type?
Those are facts about a full number, not an area code. The carrier lookup at /carrier answers them per number.
