Where the table comes from
North American Numbering Plan assignments (NANPA), compiled for 67Leads; recently added overlays may be missing. An area code shows where a number was first assigned, not where its owner is today: mobile numbers move with people. The business counts are live from the 67Leads warehouse, by the area code of each listing's phone number.

Questions
Type the three digits, or a whole phone number, in the box above. You get the state or province, the main cities it covers, its time zone and any overlay codes.
A second code added to the same area when the first runs out of numbers. Both codes cover the same places, which is why local calls there need all ten digits.
No. 800, 833, 844, 855, 866, 877 and 888 are toll-free codes: the number can ring anywhere in the US or Canada.
Usually. A few areas cross a time zone line, such as 850 in the Florida panhandle or 915 in El Paso; the result names every zone an area spans.
