Got a call from an unknown area code?
Do not assume a familiar-looking number is safe. Scammers can fake any area code, including local and toll-free ones. Warning signs:
- Pressure to act immediately, or threats about arrest, account closure or a package problem.
- Requests for payment by gift card, wire transfer, cryptocurrency or a payment app.
- Requests for passwords, verification codes or remote access to your computer or phone.
- A caller who cannot be verified through the company's official website or published number.
If in doubt, hang up and call the company back on a number from its official website. Report scam calls at reportfraud.ftc.gov, and forward spam texts to 7726. You can also register on the National Do Not Call Registry at donotcall.gov.

Frequently asked questions
What is an area code?
An area code is the first three digits of a 10-digit North American phone number. It identifies a geographic region — or, for toll-free numbers, a non-geographic service. The United States, Canada and much of the Caribbean share the +1 country code under the North American Numbering Plan (NANP).
How do I look up an area code?
Type the 3-digit code, or a full phone number, into the lookup box at the top of this page. You will see the location, main cities, time zone and current local time for that code.
Are toll-free calls really free?
For the caller, yes — the business receiving the call pays for it. Toll-free prefixes are 800, 833, 844, 855, 866, 877 and 888. Note that calling a US toll-free number from outside the US and Canada usually does not work, or may be charged.
Why do some cities have several area codes?
When a city runs out of numbers, a new code is added as an "overlay" covering the same area. Neighbors in the same city can then have different area codes, which is why 10-digit dialing is now standard in most places.
How do I dial a US or Canadian number from abroad?
Dial your country's international prefix, then 1 (the North American country code), then the area code and the 7-digit number — for example, +1 212 555 0132.
