Area code 708

Area code 708 serves Illinois, including La Grange, Chicago Heights and Blue Island (Central time). It has been in service since November 11, 1989 and shares its area with 464.

Phone companies holding 708 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 70% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
