area codes 703 and 571
the 1995 split was intended to be a long-term solution. however, within four years, 703 was close to exhaustion due to the proliferation of cell phones, fax machines, and pagers, as well as northern virginia's explosive growth. to solve this problem, area code 571 was introduced on march 1, 2000, as an overlay to 703. area code 571 serves most new telephone numbers; while it is primarily associated with mobile telephone lines, it is also used for new landline numbers, including the united states patent and trademark office upon moving to alexandria; the transportation security administration, which was created in 2001 and has its headquarters in arlington; and the fairfax county public schools, which moved its headquarters to the falls church area in 2006.
