Tools (8)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • area_codes_for_cityArea codes for a city

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

  • area_codes_for_stateArea codes for a state/province

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

  • check_number_reputationCheck a number's community + FTC spam signal

    Spam signal for a US/Canada number from areacode.fyi: the UNVERIFIED crowd-sourced community signal ('low' = looked up, 'mid'/'high' = user reports) PLUS public FTC Do Not Call complaint data when present (complaint count, % robocalls, top subject, date range). Caller ID can be spoofed — none of this proves a number is currently fraudulent.

  • explain_area_code_topicExplain a phone / area-code topic

    Source-backed explanation of a phone-numbering topic, suitable for answering end users.

  • is_scam_area_codeIs an area code a scam?

    Explain whether an area code is associated with scams. An area code is never a scam by itself; returns that context + spoofing notes, PLUS an aggregate of public FTC Do Not Call complaints about specific numbers shown with that code (how many flagged numbers, total complaints, top subjects, worst offenders).

  • lookup_area_codeLook up an area code

    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.

  • lookup_carrierLook up a number's carrier (assigned block)

    Look up the carrier, line type (wireless/landline), and rate center that a US/Canada number's NPA-NXX block was assigned to — covering nearly every active area code. Based on public block-allocation data, NOT a live lookup: if the number was ported the current carrier differs. Not for caller identity, fraud, or FCRA decisions.

  • lookup_phone_numberLook up a phone number

    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.
