Lehigh Valley - Telecommunications

Telecommunications

The Lehigh Valley area was once served only by the 215 area code from 1947 (when the North American Numbering Plan of the Bell System went into effect) until 1994. With the region's growing population, however, Lehigh Valley areas were afforded area code 610 in 1994. Today, the Lehigh Valley is covered by 610. An overlay area code, 484, was added to the 610 service area in 1999. A plan to introduce area code 835 as an additional overlay was rescinded in 2001.
