QUESTIONS
- Which area codes are covered?
- In-service codes across the North American Numbering Plan: the US, Canada, territories, Caribbean islands, and service codes such as toll-free. A code not in the list is shown as a miss.
- 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?
- For a full phone number, GET /phone/{number} returns its country, formats, and numbering-plan details. The area-code directory on this site lists the individual codes.
- 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.
