History of the 630 Area Code
The 630 area code was introduced in 1996 as a result of a geographic split from the older 708 code. This split was necessitated by the growing demand for telephone numbers in Chicago’s suburban areas, driven by population growth and the expansion of telecommunications services. Over the years, the numbering needs of businesses and residents increased further, leading to the addition of overlay codes.
Key milestones include:
- 1996: Geographic split from 708, forming the 630 code to serve suburban regions.
- 2007: Overlay area code 331 was established to address the continued demand for new numbers in the same region.
