Area code list questions How many area codes are there in the United States? NANPA's area code database (file dated October 26, 2026) lists 372 geographic area codes in service across the 50 states and the District of Columbia, plus 6 in U.S. territories. It also lists 7 toll-free codes, which are not tied to any place.
Which state has the most area codes? California, with 41 area codes in service. Texas has 29, and Florida and New York have 23 each. 11 states have a single area code each, among them Alaska, Delaware, and Hawaii.
What is the newest area code? Area code 465 in New York, in service since June 18, 2026, is the most recent geographic code in NANPA's list. It is an overlay that shares its territory with 347, 718, 917, and 929.
Can an area code cover more than one time zone? Yes. 22 area codes in the 50 states span two time zones in NANPA's data, for example 208 (Idaho, Mountain and Pacific), 219 (Indiana, Eastern and Central), and 270 (Kentucky, Eastern and Central). Check the local time before you call a number in one of these codes.
Are 800 numbers area codes? Yes, but not geographic ones. 800, 833, 844, 855, 866, 877, and 888 are toll-free codes: the business that owns the number pays for the call, and the number is not tied to a city or state.
