Look up a North American (NANP) area code: country, state/province, principal city and served cities, time zone, current local time, 10-digit-dialing flag, overlay codes, and nearby codes. Returns a canonical areacode.fyi URL and the NANPA source date.

Parse and validate a US/Canada (NANP) phone number. Returns whether the format is valid, the E.164 form, the area code, the likely region and time zone, and the current local time there. Area-code level only — NOT the caller's identity, exact location, or live carrier; caller ID can be spoofed.

Look up the carrier, line type (wireless/landline), and rate center that a US/Canada number's NPA-NXX block was assigned to. Based on public block-allocation data — NOT a live lookup: if the number was ported the current carrier differs, and coverage currently spans major metros (uncovered area codes return covered:false). Not for caller identity, fraud, or FCRA decisions.

List the area codes that serve a US or Canadian city. Optionally pass a state/province to disambiguate cities that share a name.

List every area code in a US state or Canadian province.

Explain whether an area code is associated with scams. An area code is never a scam by itself; this returns that context plus spoofing notes — caller ID can be faked, so judge calls by what they ask for, not the area code.

Return the UNVERIFIED, crowd-sourced community signal for a US/Canada number from areacode.fyi: 'low' (people have looked it up), 'mid'/'high' (it has user reports). Caller ID can be spoofed — this is never proof a specific number is fraudulent.
