Arlington Heights, IL is currently using two area codes 224 and 847. Arlington Heights, IL utilizes an area
code overlay in which area codes 224 and 847 serve the same geographic area. The area code overlay which is in use in Arlington Heights, IL today was established in 2002 at which time area code 224 was
created as an overlay of area code 847. Area code 847 was originally established in 1996. Ten digit dialing (area code + seven digit number) is necessary in Arlington Heights because two different homes in
the same geographic area can have the same seven digit phone number but each would have a different area code.
