How do you find out where an area code is?
Search the three-digit code above. Every North American area code starts with a digit from 2 to 9, covers a state, province, or metro area, and may share that territory with one or more overlay codes. Toll-free codes (800, 833, 844, 855, 866, 877, 888) are not geographic at all, and a handful of codes people search for were never assigned to anyone.
Step by step
How to use the area code lookup
- 1
Enter the three digits
Type an area code, or search by city or state to find which codes serve it. Codes that are not in service are flagged rather than hidden, because those are the ones that turn up on spoofed caller ID. - 2
Check what kind of code it is
Geographic codes map to a place. Toll-free codes such as 800 and 888 map to no place at all. Codes starting 0 or 1 are not valid area codes and cannot belong to a real subscriber. - 3
Dial it correctly
Ten digits within North America, prefixed with 1 for long distance, or +1 followed by the ten digits from anywhere else in the world.
How it works
What an area code can and cannot tell you
Area codes were designed in 1947 to route calls geographically, and for forty years they did exactly that. Two things broke the assumption that a code tells you where someone is:
- Number portability. People keep their mobile number when they move. A 212 number today may belong to someone who has not lived in Manhattan for fifteen years.
- Overlays. When a code runs out of numbers, a second code is laid over the same territory rather than splitting it. That is why 213 and 323, or 801 and 385, serve identical areas and why ten-digit dialing became mandatory.
What an area code is still good for is time zone, which is why every code page here names one. If you are calling back an unknown number, knowing whether it is 7am or 7pm there is usually the more useful fact.
Frequently asked questions
How do I find out where an area code is?
Type the three digits into the search above. You get the state or province, the main cities, the current time zone, and any overlay codes covering the same territory. Remember that a mobile number keeps its area code when its owner moves; the code shows where the number was issued, not where the person is.
Can I look up who owns a phone number?
Not from the area code. Area codes identify a region, not a person. Public reverse-lookup services are unreliable for mobiles, and carriers do not publish subscriber data. If an unknown number keeps calling, blocking it is more effective than identifying it.
Why does my caller ID show an area code that does not exist?
Because it was spoofed. Several three-digit combinations people search for (444, 846, 677) have never been assigned to any region, so no real subscriber can have one. If your carrier shows it, the calling party manufactured the caller ID.
What is my area code?
It is the first three digits of your own ten-digit number, after the country code. If your number is (415) 555-0123, your area code is 415. Look it up above to confirm the region it belongs to.
