Area code 610 serves Pennsylvania, including Philadelphia Suburban Zone 30, Allentown and Reading (Eastern time). It has been in service since January 8, 1994 and shares its area with 484 and 835.

Phone companies holding 610 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 55% 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.
