What is what area code is 682?

Area code 682 is an overlay area code serving most of the Dallas-Fort Worth metroplex in Texas. This means it was added to an existing area code (primarily 214, 469, 972, and 817 in the DFW area) to handle the increasing number of phone lines needed in the region. Calls within the DFW area might be made between numbers with different area codes (like 682 and 214), but long-distance rates won't apply.
