Is 111 a real US area code?
No. 111 is not an active or assignable US area code, and it never has been. It does not map to any city, state, or region, so there is no location to look up.
US area codes are three-digit prefixes governed by the North American Numbering Plan. Under those rules the first digit of an area code must be between 2 and 9 — which is exactly why 111 cannot exist as an area code.
Why 111 can't be an area code
The digits 0 and 1 are reserved at the start of a dialed number: 1 is the long-distance trunk prefix (as in 1-800) and 0 reaches the operator. Because an area code cannot begin with either, no valid area code starts with 1 — ruling out 111 entirely.
111 is also not a valid service code. The three-digit "N11" codes reserved for special services are 211, 311, 411, 511, 611, 711, 811, and 911. None of them is 111, so 111 has no meaning in the US dialing plan at all.
Why you might see a call from 111
If your phone shows an incoming call from "111," it is not coming from a real 111 area code. The most common explanations are:
- Caller-ID spoofing — scammers can display almost any string, including invalid ones, to disguise the real origin.
- A misread or truncated number — a longer or international number can be displayed incompletely by some devices.
- An internal PBX extension — some office phone systems use short codes like 111 for internal calls, which can surface on caller ID.
- An international emergency line — 111 is the emergency number in a few countries (for example New Zealand), unrelated to US dialing.
What to do about a 111 call
Treat an unexpected call showing 111 the same way you would any suspicious call: do not share personal or payment information, and do not call back a number you cannot verify.
If the call was a scam or used a spoofed number, you can report it to the FCC at consumercomplaints.fcc.gov. For general spoofing guidance, see the FCC spoofing page.
