Area codes serving Cicero
Cicero sits in Illinois, part of the Midwest region and the Central Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 464, 708.
The original code is 708 (in service since 1989). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number
When you activate a new line in Cicero, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 708), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
