What is +1 256?

+1 256 is a telephone area code in the North American Numbering Plan (NANP) that covers the northern portion of the state of Alabama, including the cities of Huntsville, Decatur, Florence, and Gadsden. The area code was created in 1998 as a split from the original 205 area code that covered the entire state of Alabama. Currently, +1 256 is one of the four area codes in Alabama, along with +1 205, +1 251, and +1 334. The +1 prefix is the country code for the United States, and is used before all NANP area codes.
